Come together and dementia risk. Come together and dementia risk. Come together and estimate estimate estimate which risk factors um are strongly sort which risk factors um are strongly sort which risk factors um are strongly sort of we think we can causally link them to of we think we can causally link them to of we think we can causally link them to dementia risk longterm that are dementia risk longterm that are dementia risk longterm that are potentially modifiable. and they potentially modifiable. and they potentially modifiable. and they estimate that when you sum up all those estimate that when you sum up all those estimate that when you sum up all those different risk factors, um it's a it's different risk factors, um it's a it's different risk factors, um it's a it's sort of a statistical approach that sort of a statistical approach that sort of a statistical approach that says, imagine that this risk factor says, imagine that this risk factor says, imagine that this risk factor didn't exist at all. What proportion of didn't exist at all. What proportion of didn't exist at all. What proportion of dementias would we expect to to never dementias would we expect to to never dementias would we expect to to never happen? Um and when you add all those happen? Um and when you add all those happen? Um and when you add all those up, the number they currently have is up, the number they currently have is up, the number they currently have is 45% of dementias are potentially 45% of dementias are potentially 45% of dementias are potentially preventable. Um and this is published in preventable. Um and this is published in preventable. Um and this is published in the Lancet, you know, the one of the the Lancet, you know, the one of the the Lancet, you know, the one of the premier medical journals uh in the premier medical journals uh in the premier medical journals uh in the world. So at least 45% are thought to be world. So at least 45% are thought to be world. So at least 45% are thought to be preventable. And there are risk factors preventable. And there are risk factors preventable. And there are risk factors that are strongly linked to dementia that are strongly linked to dementia that are strongly linked to dementia risk are also modifiable that they risk are also modifiable that they risk are also modifiable that they weren't yet able to add into their weren't yet able to add into their weren't yet able to add into their models that you know some people think models that you know some people think models that you know some people think it could even be more than that. it could even be more than that. it could even be more than that.

Potentially the >> that's Great question. Potentially the >> that's Great question. Potentially the treatment of heart disease and we've treatment of heart disease and we've treatment of heart disease and we've gotten much better at treating heart gotten much better at treating heart gotten much better at treating heart disease in the last 50 60 years that has disease in the last 50 60 years that has disease in the last 50 60 years that has then changed the the age specific then changed the the age specific then changed the the age specific incidence of dementia in the population. incidence of dementia in the population. incidence of dementia in the population. And what I mean by that is that at any And what I mean by that is that at any And what I mean by that is that at any given age you are now less likely to be given age you are now less likely to be given age you are now less likely to be diagnosed with dementia than you were 20 diagnosed with dementia than you were 20 diagnosed with dementia than you were 20 or 30 years ago. So at 70 years old or or 30 years ago. So at 70 years old or or 30 years ago. So at 70 years old or 80 years old you're less likely to be 80 years old you're less likely to be 80 years old you're less likely to be diagnosed with dementia now than you diagnosed with dementia now than you diagnosed with dementia now than you would have been done uh previously. And would have been done uh previously. And would have been done uh previously. And part of that is thought to to be because part of that is thought to to be because part of that is thought to to be because we've gotten so good at treating we've gotten so good at treating we've gotten so good at treating cardiovascular disease, which is a risk cardiovascular disease, which is a risk cardiovascular disease, which is a risk factor both for vascular dementia, which factor both for vascular dementia, which factor both for vascular dementia, which makes up something like 10 to 20% of makes up something like 10 to 20% of makes up something like 10 to 20% of dementia, and Alzheimer's disease, um, dementia, and Alzheimer's disease, um, dementia, and Alzheimer's disease, um, which has a a vascular, you know, which has a a vascular, you know, which has a a vascular, you know, disease component. Um, so, and that's, disease component. Um, so, and that's, disease component. Um, so, and that's, you know, Alzheimer's disease is maybe you know, Alzheimer's disease is maybe you know, Alzheimer's disease is maybe 60 to 80% of dementia. So, at least 70 60 to 80% of dementia. So, at least 70 60 to 80% of dementia. So, at least 70 to 90% of dementia do have to 90% of dementia do have to 90% of dementia do have cardiovascular risk factors as a risk. cardiovascular risk factors as a risk. cardiovascular risk factors as a risk. And that's something that we've actually And that's something that we've actually And that's something that we've actually gotten better at treating. Um, but even gotten better at treating. Um, but even gotten better at treating. Um, but even if you go back to the the 50s and 60s, if you go back to the the 50s and 60s, if you go back to the the 50s and 60s, the Seattle longitudinal study, it was the Seattle longitudinal study, it was the Seattle longitudinal study, it was one of the first studies where rather one of the first studies where rather one of the first studies where rather than taking a whole population and than taking a whole population and than taking a whole population and looking at their cognitive function and looking at their cognitive function and looking at their cognitive function and seeing, well, you know, the average seeing, well, you know, the average seeing, well, you know, the average 70-year-old has lower cognitive function 70-year-old has lower cognitive function 70-year-old has lower cognitive function than the average 50-year-old, and we're than the average 50-year-old, and we're than the average 50-year-old, and we're talking broad cognitive function, if you talking broad cognitive function, if you talking broad cognitive function, if you test multiple different um multiple test multiple different um multiple test multiple different um multiple different functions, you sort of add different functions, you sort of add different functions, you sort of add them up. This was one of the first them up. This was one of the first them up. This was one of the first studies where rather than just taking a studies where rather than just taking a studies where rather than just taking a big population and looking at cognitive big population and looking at cognitive big population and looking at cognitive function across that group, they looked function across that group, they looked function across that group, they looked at the same people over a long period of at the same people over a long period of at the same people over a long period of time. And so he brought people back time. And so he brought people back time. And so he brought people back every seven years and rememeasured their every seven years and rememeasured their every seven years and rememeasured their cognitive function. Um, and what he cognitive function. Um, and what he cognitive function. Um, and what he found first one one of the papers they found first one one of the papers they found first one one of the papers they published was that cardiovascular risk published was that cardiovascular risk published was that cardiovascular risk factors were strong predictors of change factors were strong predictors of change factors were strong predictors of change over time. So we knew that back in the over time. So we knew that back in the over time. So we knew that back in the you know 60s and 70s when he first you know 60s and 70s when he first you know 60s and 70s when he first published those data. And then the other published those data. And then the other published those data. And then the other thing they found was that the average thing they found was that the average thing they found was that the average effect so more than 50% of people effect so more than 50% of people effect so more than 50% of people maintained cognitive function from their maintained cognitive function from their maintained cognitive function from their 50s into their 60s7s and 80s. Nowadays 50s into their 60s7s and 80s. Nowadays 50s into their 60s7s and 80s. Nowadays we call people who do that super aes we call people who do that super aes we call people who do that super aes right because we think it's so unusual right because we think it's so unusual right because we think it's so unusual but actually we knew even back then that but actually we knew even back then that but actually we knew even back then that the the majority of people sort of 50 the the majority of people sort of 50 the the majority of people sort of 50 60% maintained cognitive function into 60% maintained cognitive function into 60% maintained cognitive function into those later decades those later decades those later decades >> and those data were actually used to >> and those data were actually used to >> and those data were actually used to raise the retirement age in the US in raise the retirement age in the US in raise the retirement age in the US in the 1980s. M the 1980s. M the 1980s. M >> um so we've had some inklings of this uh >> um so we've had some inklings of this uh >> um so we've had some inklings of this uh for a long time. It's just that getting for a long time. It's just that getting for a long time. It's just that getting a big enough set of data, finding a a big enough set of data, finding a a big enough set of data, finding a systematized way to you know really sort systematized way to you know really sort systematized way to you know really sort of put it together in and then frame it of put it together in and then frame it of put it together in and then frame it as prevention rather than these are just as prevention rather than these are just as prevention rather than these are just risk factors, right? that and knowing risk factors, right? that and knowing risk factors, right? that and knowing that we if we treat heart disease for that we if we treat heart disease for that we if we treat heart disease for example and as a result age specific example and as a result age specific example and as a result age specific instance of of dementia comes down which instance of of dementia comes down which instance of of dementia comes down which is what is sort of like part of the is what is sort of like part of the is what is sort of like part of the hypothesis of that hypothesis of that hypothesis of that >> then for the first time we can say oh >> then for the first time we can say oh >> then for the first time we can say oh yeah if we do something at the yeah if we do something at the yeah if we do something at the population level we can see changes in population level we can see changes in population level we can see changes in dementia risk therefore we can now start dementia risk therefore we can now start dementia risk therefore we can now start to talk about prevention to talk about prevention to talk about prevention >> the statistics uh bear out a a rapid >> the statistics uh bear out a a rapid >> the statistics uh bear out a a rapid rise in Alzheimer's and dementia I rise in Alzheimer's and dementia I rise in Alzheimer's and dementia I looked into this from What I gather uh looked into this from What I gather uh looked into this from What I gather uh the it's due to double in the US by60 the it's due to double in the US by60 the it's due to double in the US by60 going from 7 to 14 million. There are going from 7 to 14 million. There are going from 7 to 14 million. There are currently somewhere between 6.7 and 7.1 currently somewhere between 6.7 and 7.1 currently somewhere between 6.7 and 7.1 million people in the United States with million people in the United States with million people in the United States with Alzheimer's. This is predicted to be 139 Alzheimer's. This is predicted to be 139 Alzheimer's. This is predicted to be 139 million worldwide by 2050. There are 10 million worldwide by 2050. There are 10 million worldwide by 2050. There are 10 million new cases annually. My million new cases annually. My million new cases annually. My perception is that you know maybe it's perception is that you know maybe it's perception is that you know maybe it's just my age or because of what's just my age or because of what's just my age or because of what's happening with my mother that you know happening with my mother that you know happening with my mother that you know this is rampant and happening this is rampant and happening this is rampant and happening everywhere. So what is uh driving this everywhere. So what is uh driving this everywhere. So what is uh driving this and what should we understand like what and what should we understand like what and what should we understand like what you know what's what's vital to extract you know what's what's vital to extract you know what's what's vital to extract from those statistics about this from those statistics about this from those statistics about this condition. condition. condition. >> The statistics that you give and the >> The statistics that you give and the >> The statistics that you give and the ones that I gave are both true at the ones that I gave are both true at the ones that I gave are both true at the same time. meaning there's a high same time. meaning there's a high same time. meaning there's a high there's a high degree of agency in terms there's a high degree of agency in terms there's a high degree of agency in terms of prevention and yet we're also seeing of prevention and yet we're also seeing of prevention and yet we're also seeing this you know rapid rise well at the this you know rapid rise well at the this you know rapid rise well at the same time same time same time >> and the age specific incidence has >> and the age specific incidence has >> and the age specific incidence has declined over the last hundred years declined over the last hundred years declined over the last hundred years right so you're less likely to be right so you're less likely to be right so you're less likely to be diagnosed with dementia at 75 years old diagnosed with dementia at 75 years old diagnosed with dementia at 75 years old now than you ever have been but you're now than you ever have been but you're now than you ever have been but you're also more likely to have to ever be also more likely to have to ever be also more likely to have to ever be diagnosed with dementia because we're diagnosed with dementia because we're diagnosed with dementia because we're going to live much longer living longer going to live much longer living longer going to live much longer living longer >> yeah both of those things are true at >> yeah both of those things are true at >> yeah both of those things are true at the same time people are projecting that the same time people are projecting that the same time people are projecting that the burden of denure the burden of denure the burden of denure may double or triple in the next few may double or triple in the next few may double or triple in the next few decades. Um, and that's largely due to decades. Um, and that's largely due to decades. Um, and that's largely due to an aging population. But some people an aging population. But some people an aging population. But some people such as those who have analyzed the data such as those who have analyzed the data such as those who have analyzed the data and shown that age specific instance has and shown that age specific instance has and shown that age specific instance has decreased have suggested that maybe that decreased have suggested that maybe that decreased have suggested that maybe that that sort of projection is a bit of an that sort of projection is a bit of an that sort of projection is a bit of an overestimate and the the increase in overestimate and the the increase in overestimate and the the increase in burden may not be that large. However, burden may not be that large. However, burden may not be that large. However, things that seem to be contributing to things that seem to be contributing to things that seem to be contributing to it in particular are the ongoing it in particular are the ongoing it in particular are the ongoing worsening metabolic and cardiovascular worsening metabolic and cardiovascular worsening metabolic and cardiovascular health of of the population. So, we're health of of the population. So, we're health of of the population. So, we're still seeing even though many things still seeing even though many things still seeing even though many things have improved um smoking, heart disease have improved um smoking, heart disease have improved um smoking, heart disease treatment, access to education, access treatment, access to education, access treatment, access to education, access to complex cognitively stimulating jobs, to complex cognitively stimulating jobs, to complex cognitively stimulating jobs, particularly for women, which has which particularly for women, which has which particularly for women, which has which has sort of massively improved over the has sort of massively improved over the has sort of massively improved over the last 100 or 50 years or so. that is last 100 or 50 years or so. that is last 100 or 50 years or so. that is contributing to some of that decline in contributing to some of that decline in contributing to some of that decline in age specific incidents. At the same age specific incidents. At the same age specific incidents. At the same time, we're seeing worsening in obesity time, we're seeing worsening in obesity time, we're seeing worsening in obesity rates and type two diabetes rates and we rates and type two diabetes rates and we rates and type two diabetes rates and we know that those are significant, you know that those are significant, you know that those are significant, you know, high blood pressure is one of the know, high blood pressure is one of the know, high blood pressure is one of the most important predictors of of dementia most important predictors of of dementia most important predictors of of dementia risk. So, if we don't manage to change risk. So, if we don't manage to change risk. So, if we don't manage to change that trajectory, that's one of that's that trajectory, that's one of that's that trajectory, that's one of that's one of those are one of the things that one of those are one of the things that one of those are one of the things that are expected to to continue to drive up are expected to to continue to drive up are expected to to continue to drive up the burden of dementia. However, we say the burden of dementia. However, we say the burden of dementia. However, we say that in the age of the GLP-1 receptor that in the age of the GLP-1 receptor that in the age of the GLP-1 receptor agonist and the the other the other agonist and the the other the other agonist and the the other the other therapies in that in that class which therapies in that in that class which therapies in that in that class which have huge effects on cardiovascular have huge effects on cardiovascular have huge effects on cardiovascular disease risk, blood pressure, uh blood disease risk, blood pressure, uh blood disease risk, blood pressure, uh blood sugar. So, it's possible that actually sugar. So, it's possible that actually sugar. So, it's possible that actually we're we're also changing that we're we're also changing that we're we're also changing that trajectory due to the nature of those trajectory due to the nature of those trajectory due to the nature of those medications which if started early medications which if started early medications which if started early enough you would expect to decrease enough you would expect to decrease enough you would expect to decrease dementia risk because of the effect they dementia risk because of the effect they dementia risk because of the effect they have on metabolic health. given the high have on metabolic health. given the high have on metabolic health. given the high degree of agency that we have to stave degree of agency that we have to stave degree of agency that we have to stave this off.

So it's things like um education um and we know things like um education um and we know things like um education um and we know that cognitive stimulus is is really that cognitive stimulus is is really that cognitive stimulus is is really important. It's um maintaining important. It's um maintaining important. It's um maintaining uh sensory input. So hearing loss and uh sensory input. So hearing loss and uh sensory input. So hearing loss and and vision loss are significant risk and vision loss are significant risk and vision loss are significant risk factors for dementia. It's all the factors for dementia. It's all the factors for dementia. It's all the cardiovascular stuff that we talked cardiovascular stuff that we talked cardiovascular stuff that we talked about.

The way I think about it is >> Exactly. The way I think about it is >> Exactly. The way I think about it is very similar to um a stimulus recovery very similar to um a stimulus recovery very similar to um a stimulus recovery adaptation model that you might see in adaptation model that you might see in adaptation model that you might see in physical exercise. So um if you're physical exercise. So um if you're physical exercise. So um if you're trying to improve physical performance, trying to improve physical performance, trying to improve physical performance, we know that the primary driver of we know that the primary driver of we know that the primary driver of improved cardiovascular fitness or improved cardiovascular fitness or improved cardiovascular fitness or improved muscle size or strength is the improved muscle size or strength is the improved muscle size or strength is the stimulus that you apply to it. Right? stimulus that you apply to it. Right? stimulus that you apply to it. Right? So, the training that you do for your So, the training that you do for your So, the training that you do for your marathon or the lifting you do in the marathon or the lifting you do in the marathon or the lifting you do in the the in the gym if you're trying to build the in the gym if you're trying to build the in the gym if you're trying to build uh muscle strength, you can improve uh muscle strength, you can improve uh muscle strength, you can improve how you adapt to those stimuli by how you adapt to those stimuli by how you adapt to those stimuli by attending to your nutrition and attending to your nutrition and attending to your nutrition and attending to your recovery. But the attending to your recovery. But the attending to your recovery. But the stimulus is the most important thing, stimulus is the most important thing, stimulus is the most important thing, right? I like to lift weights and right? I like to lift weights and right? I like to lift weights and unfortunately like no matter how many unfortunately like no matter how many unfortunately like no matter how many naps and protein shakes I have, I can't naps and protein shakes I have, I can't naps and protein shakes I have, I can't I won't get bigger biceps unless I, you I won't get bigger biceps unless I, you I won't get bigger biceps unless I, you know, do some bicep curls. Mhm. know, do some bicep curls. Mhm. know, do some bicep curls. Mhm. >> And the brain I think is essentially the >> And the brain I think is essentially the >> And the brain I think is essentially the same. So the thesis in the book is that same. So the thesis in the book is that same. So the thesis in the book is that how we use our brains is the primary how we use our brains is the primary how we use our brains is the primary determinant of how they will function. determinant of how they will function. determinant of how they will function. Um and that means that we need stimulus. Um and that means that we need stimulus. Um and that means that we need stimulus. Um and I know that this is slightly Um and I know that this is slightly Um and I know that this is slightly controversial in the current world where controversial in the current world where controversial in the current world where we're I I believe that we're we're we're I I believe that we're we're we're I I believe that we're we're chronically overstimulated while being chronically overstimulated while being chronically overstimulated while being under stimulated at the same time. We're under stimulated at the same time. We're under stimulated at the same time. We're sort of constantly bombarded with sort of constantly bombarded with sort of constantly bombarded with multitasking and multimedia and social multitasking and multimedia and social multitasking and multimedia and social media and these things that don't truly media and these things that don't truly media and these things that don't truly drive improvements in brain function and drive improvements in brain function and drive improvements in brain function and feeling overwhelmed because of it whilst feeling overwhelmed because of it whilst feeling overwhelmed because of it whilst not being able to attend to the real not being able to attend to the real not being able to attend to the real focused deep um learning and skill focused deep um learning and skill focused deep um learning and skill development which is what really drives development which is what really drives development which is what really drives brain function. And so the stimuli that brain function. And so the stimuli that brain function. And so the stimuli that we can think about that sort of drive we can think about that sort of drive we can think about that sort of drive this whole system uh include um this whole system uh include um this whole system uh include um education and learning any kind of skill education and learning any kind of skill education and learning any kind of skill development be that music, languages, development be that music, languages, development be that music, languages, complex motor skills and then also complex motor skills and then also complex motor skills and then also social like social interactions which we social like social interactions which we social like social interactions which we know is a a primary driver of both human know is a a primary driver of both human know is a a primary driver of both human brain evolution and then human brain brain evolution and then human brain brain evolution and then human brain development and maintenance. So we need development and maintenance. So we need development and maintenance. So we need to think about like how we're using our to think about like how we're using our to think about like how we're using our brains. But then once you've stimulated brains. But then once you've stimulated brains. But then once you've stimulated a region of the brain by engaging it in a region of the brain by engaging it in a region of the brain by engaging it in some task, you need a supply of the some task, you need a supply of the some task, you need a supply of the things that allow that to happen. So now things that allow that to happen. So now things that allow that to happen. So now we're kind of getting into what I call we're kind of getting into what I call we're kind of getting into what I call the 3S model. The first S is stimulus. the 3S model. The first S is stimulus. the 3S model. The first S is stimulus. The second S is supply. And so right, if The second S is supply. And so right, if The second S is supply. And so right, if you activate a part of the brain, the you activate a part of the brain, the you activate a part of the brain, the local cells, the neurons, the astrotes, local cells, the neurons, the astrotes, local cells, the neurons, the astrotes, they stimulate the blood vessels to they stimulate the blood vessels to they stimulate the blood vessels to dilate, to widen, to bring in more blood dilate, to widen, to bring in more blood dilate, to widen, to bring in more blood flow. Uh so that's where we need good flow. Uh so that's where we need good flow. Uh so that's where we need good cardiovascular health, right? You you cardiovascular health, right? You you cardiovascular health, right? You you need that to be able to respond to uh need that to be able to respond to uh need that to be able to respond to uh changes in activity in the brain. Um and changes in activity in the brain. Um and changes in activity in the brain. Um and then you also need a supply of energy. then you also need a supply of energy. then you also need a supply of energy. So that's where we need good uh energy So that's where we need good uh energy So that's where we need good uh energy regulation. Um good metabolic health regulation. Um good metabolic health regulation. Um good metabolic health because glucco glucose is going to be because glucco glucose is going to be because glucco glucose is going to be our primary uh source of energy. But our primary uh source of energy. But our primary uh source of energy. But ketones, lactate, right? Those those ketones, lactate, right? Those those ketones, lactate, right? Those those those can play a role too. Um and then those can play a role too. Um and then those can play a role too. Um and then we need a supply of nutrients to kind of we need a supply of nutrients to kind of we need a supply of nutrients to kind of run that system. So things that become run that system. So things that become run that system. So things that become critical particularly in terms of critical particularly in terms of critical particularly in terms of dementia risk are B vitamins associated dementia risk are B vitamins associated dementia risk are B vitamins associated with methylation, omega-3 fatty acids, with methylation, omega-3 fatty acids, with methylation, omega-3 fatty acids, vitamin D, iron um and then some others vitamin D, iron um and then some others vitamin D, iron um and then some others like magnesium, zinc, uh antioxidant like magnesium, zinc, uh antioxidant like magnesium, zinc, uh antioxidant vitamins like vitamin C, vitamin E, and vitamins like vitamin C, vitamin E, and vitamins like vitamin C, vitamin E, and then the antioxidant polyphenols um that then the antioxidant polyphenols um that then the antioxidant polyphenols um that you can get from colorful foods do a you can get from colorful foods do a you can get from colorful foods do a bunch of cool stuff for the brain. There bunch of cool stuff for the brain. There bunch of cool stuff for the brain. There may be some other precursors like may be some other precursors like may be some other precursors like choline or ethanolamine that you can get choline or ethanolamine that you can get choline or ethanolamine that you can get from eggs or whole grains. like those from eggs or whole grains. like those from eggs or whole grains. like those kind of provide a structural component kind of provide a structural component kind of provide a structural component and we can get into all of these and we can get into all of these and we can get into all of these different uh sections. But so we've different uh sections. But so we've different uh sections. But so we've stimulated the brain, we've brought in a stimulated the brain, we've brought in a stimulated the brain, we've brought in a supply of things that we need to kind of supply of things that we need to kind of supply of things that we need to kind of allow it to do its job. And then just allow it to do its job. And then just allow it to do its job. And then just like with um our physical performance, like with um our physical performance, like with um our physical performance, you don't get stronger when you're you don't get stronger when you're you don't get stronger when you're training, you get stronger when you rest training, you get stronger when you rest training, you get stronger when you rest and recover afterwards. So this is my and recover afterwards. So this is my and recover afterwards. So this is my third S, which is support. So sleep is a third S, which is support. So sleep is a third S, which is support. So sleep is a critical part of that. That's when all critical part of that. That's when all critical part of that. That's when all the signapses that you've generated uh the signapses that you've generated uh the signapses that you've generated uh during the day by through your skill during the day by through your skill during the day by through your skill learning are uh cemented and refined to learning are uh cemented and refined to learning are uh cemented and refined to kind of you know build part of or like kind of you know build part of or like kind of you know build part of or like build new aspects of uh structure and build new aspects of uh structure and build new aspects of uh structure and function in the brain. And we can see function in the brain. And we can see function in the brain. And we can see that with skill learning we can see the that with skill learning we can see the that with skill learning we can see the brain change on MRI scans as these sort brain change on MRI scans as these sort brain change on MRI scans as these sort of um processes are driven even in older of um processes are driven even in older of um processes are driven even in older adults in their 60s and 70s. Then we can adults in their 60s and 70s. Then we can adults in their 60s and 70s. Then we can support those processes with um what we support those processes with um what we support those processes with um what we call trophic factors. So things that call trophic factors. So things that call trophic factors. So things that like support the growth of sinapses um like support the growth of sinapses um like support the growth of sinapses um and function of neurons in the brain. So and function of neurons in the brain. So and function of neurons in the brain. So uh one that's produced during exercise uh one that's produced during exercise uh one that's produced during exercise is brain derived neurotrophic factor. Um is brain derived neurotrophic factor. Um is brain derived neurotrophic factor. Um hormones play a role here too. I mean hormones play a role here too. I mean hormones play a role here too. I mean you had an excellent episode with Lisa you had an excellent episode with Lisa you had an excellent episode with Lisa Moscone. That's really her area of Moscone. That's really her area of Moscone. That's really her area of expertise, but hormones sort of support expertise, but hormones sort of support expertise, but hormones sort of support brain function as well. Um and then we brain function as well. Um and then we brain function as well. Um and then we want to avoid things that kind of want to avoid things that kind of want to avoid things that kind of inhibit that adaptation process. So this inhibit that adaptation process. So this inhibit that adaptation process. So this is where things like alcohol, smoking, is where things like alcohol, smoking, is where things like alcohol, smoking, chronic stress, air pollution come into chronic stress, air pollution come into chronic stress, air pollution come into play. Um, and so all of these things play. Um, and so all of these things play. Um, and so all of these things interact. And the reason why I talk interact. And the reason why I talk interact. And the reason why I talk about it in this way is because it's not about it in this way is because it's not about it in this way is because it's not this massive list of 20 things you need this massive list of 20 things you need this massive list of 20 things you need to attend to. Um, because uh, stimulus to attend to. Um, because uh, stimulus to attend to. Um, because uh, stimulus drives the the processes of of drives the the processes of of drives the the processes of of adaptation and stimulus drives the adaptation and stimulus drives the adaptation and stimulus drives the processes of supply and supply drives processes of supply and supply drives processes of supply and supply drives support. They interact. support. They interact. support. They interact. >> And what you see quite clearly is that >> And what you see quite clearly is that >> And what you see quite clearly is that when you change one thing, you change when you change one thing, you change when you change one thing, you change lots of lots of things at the same time. lots of lots of things at the same time. lots of lots of things at the same time. So you can so if you start by stopping So you can so if you start by stopping So you can so if you start by stopping smoking right you've you've removed one smoking right you've you've removed one smoking right you've you've removed one risk factor but you will also see risk factor but you will also see risk factor but you will also see improvements in inflammation and improvements in inflammation and improvements in inflammation and improvements in blood pressure and improvements in blood pressure and improvements in blood pressure and you're more likely to um make other you're more likely to um make other you're more likely to um make other healthy diet like diet choices for healthy diet like diet choices for healthy diet like diet choices for example we know that that that happens example we know that that that happens example we know that that that happens or if you start to sleep better again or if you start to sleep better again or if you start to sleep better again blood pressure improves and the next day blood pressure improves and the next day blood pressure improves and the next day you feel more social and you're more you feel more social and you're more you feel more social and you're more likely to engage in cognitively likely to engage in cognitively likely to engage in cognitively stimulating tasks so I think about it stimulating tasks so I think about it stimulating tasks so I think about it this way so that there's an in for this way so that there's an in for this way so that there's an in for everybody and that in could just be one everybody and that in could just be one everybody and that in could just be one thing and then the whole sort of network thing and then the whole sort of network thing and then the whole sort of network starts to shift in your favor. starts to shift in your favor. starts to shift in your favor. >> Mhm. There's so much in there. Don't >> Mhm. There's so much in there. Don't >> Mhm. There's so much in there. Don't worry, we're going to tease out all of worry, we're going to tease out all of worry, we're going to tease out all of these things individually. Uh but I these things individually.

So, so this is actually another part of the question that you asked part of the question that you asked part of the question that you asked earlier, which is, you know, why haven't earlier, which is, you know, why haven't earlier, which is, you know, why haven't we started to think about dementia we started to think about dementia we started to think about dementia prevention in this way until very prevention in this way until very prevention in this way until very recently and I think part of it is recently and I think part of it is recently and I think part of it is because we we've been chasing down one because we we've been chasing down one because we we've been chasing down one reductionist pathway, which is the reductionist pathway, which is the reductionist pathway, which is the amaloid cascade. Um, and then that's amaloid cascade. Um, and then that's amaloid cascade. Um, and then that's kind of I think it's distracted us a kind of I think it's distracted us a kind of I think it's distracted us a bit. Not that that's not important, bit. Not that that's not important, bit. Not that that's not important, right? that should remain a part of the right? that should remain a part of the right? that should remain a part of the our whole picture, but it's kind of it our whole picture, but it's kind of it our whole picture, but it's kind of it it drew resources and attention away it drew resources and attention away it drew resources and attention away from these other things that that that from these other things that that that from these other things that that that we can talk that we can talk about.

The answer is that it's going to differ from answer is that it's going to differ from answer is that it's going to differ from person to person, of course. Um, and I person to person, of course. Um, and I person to person, of course. Um, and I think that these things shift across the think that these things shift across the think that these things shift across the life course. So, um, in younger life course. So, um, in younger life course. So, um, in younger individuals, maybe in their 30s and 40s, individuals, maybe in their 30s and 40s, individuals, maybe in their 30s and 40s, I think in general, um, they're pro, you I think in general, um, they're pro, you I think in general, um, they're pro, you know, they're probably receiving a good know, they're probably receiving a good know, they're probably receiving a good amount of of stim of of stimulation, you amount of of stim of of stimulation, you amount of of stim of of stimulation, you know, unless they're just like at home know, unless they're just like at home know, unless they're just like at home scrolling on Instagram all day, which is scrolling on Instagram all day, which is scrolling on Instagram all day, which is going to be some portion of the going to be some portion of the going to be some portion of the population. population. population. >> But if you think about um knowledge >> But if you think about um knowledge >> But if you think about um knowledge workers in their 30s and 40s, they're workers in their 30s and 40s, they're workers in their 30s and 40s, they're probably going to be doing some kind of probably going to be doing some kind of probably going to be doing some kind of complex cognitive stimulating work.

Um, and I think that's one of retired. Um, and I think that's one of retired. Um, and I think that's one of the reasons why um, cognitive decline the reasons why um, cognitive decline the reasons why um, cognitive decline tends to accelerate a retirement is tends to accelerate a retirement is tends to accelerate a retirement is because we lose those those stimuli.

Like an important place to start is that these technologies aren't is that these technologies aren't is that these technologies aren't inherently bad. It all comes down to how inherently bad. It all comes down to how inherently bad. It all comes down to how we engage with them, right? So if so we engage with them, right? So if so we engage with them, right? So if so there's even some evidence suggests that there's even some evidence suggests that there's even some evidence suggests that something like 5 minutes of scrolling on something like 5 minutes of scrolling on something like 5 minutes of scrolling on Instagram as long as it's not making you Instagram as long as it's not making you Instagram as long as it's not making you mad because of you know of some uh mad because of you know of some uh mad because of you know of some uh emotional political information or um as emotional political information or um as emotional political information or um as long as it's not only exposing you to long as it's not only exposing you to long as it's not only exposing you to people who are richer, better looking, people who are richer, better looking, people who are richer, better looking, more successful than you are which sort more successful than you are which sort more successful than you are which sort of like make makes you inherently feel of like make makes you inherently feel of like make makes you inherently feel worse about yourself that has sort of worse about yourself that has sort of worse about yourself that has sort of like triggered triggers effects in our like triggered triggers effects in our like triggered triggers effects in our physiology that can negatively affect physiology that can negatively affect physiology that can negatively affect our health. If it's just like you spend our health. If it's just like you spend our health. If it's just like you spend five minutes looking at dogs doing funny five minutes looking at dogs doing funny five minutes looking at dogs doing funny things, which is a lot of my Instagram things, which is a lot of my Instagram things, which is a lot of my Instagram feed, right? That can actually be a real feed, right? That can actually be a real feed, right? That can actually be a real mental break that would allow you to go mental break that would allow you to go mental break that would allow you to go back and and do hard work. But the back and and do hard work. But the back and and do hard work. But the problem is that's not what that's not problem is that's not what that's not problem is that's not what that's not how we're using it. Um we're constantly how we're using it. Um we're constantly how we're using it. Um we're constantly we're using it for extended periods of we're using it for extended periods of we're using it for extended periods of time plus using it while we do something time plus using it while we do something time plus using it while we do something else, right? So you're scrolling on else, right? So you're scrolling on else, right? So you're scrolling on Instagram while you've got Netflix on or Instagram while you've got Netflix on or Instagram while you've got Netflix on or while you're doing emails or while while you're doing emails or while while you're doing emails or while you're in a in a Zoom meeting. And what you're in a in a Zoom meeting. And what you're in a in a Zoom meeting. And what you see, there's some really interesting you see, there's some really interesting you see, there's some really interesting studies where they look at how much studies where they look at how much studies where they look at how much people multitask across different people multitask across different people multitask across different multimedia in that way. And what you see multimedia in that way. And what you see multimedia in that way. And what you see is that just as you'd expect, um, if if is that just as you'd expect, um, if if is that just as you'd expect, um, if if the stimulus is the primary driver of the stimulus is the primary driver of the stimulus is the primary driver of how our brains function, our brains do how our brains function, our brains do how our brains function, our brains do actually adapt to that. So people who do actually adapt to that. So people who do actually adapt to that. So people who do that kind of thing are better at that kind of thing are better at that kind of thing are better at multitasking. And the way you would test multitasking. And the way you would test multitasking. And the way you would test that in in a study is you have one that in in a study is you have one that in in a study is you have one cognitive task and then you have them do cognitive task and then you have them do cognitive task and then you have them do have to do another like another have to do another like another have to do another like another cognitive task at the same time. And cognitive task at the same time. And cognitive task at the same time. And everybody who multitasks does worse on everybody who multitasks does worse on everybody who multitasks does worse on both tasks, right? Because the human both tasks, right? Because the human both tasks, right? Because the human brain actually isn't it cannot multitask brain actually isn't it cannot multitask brain actually isn't it cannot multitask properly. It can't give full focused properly. It can't give full focused properly. It can't give full focused attention to two different things at the attention to two different things at the attention to two different things at the same time. same time. same time. >> But people who do a lot of like >> But people who do a lot of like >> But people who do a lot of like Instagram plus Netflix plus Zoom Instagram plus Netflix plus Zoom Instagram plus Netflix plus Zoom meetings etc. um they are better. They meetings etc. um they are better. They meetings etc. um they are better. They they have less of a multitasking cost they have less of a multitasking cost they have less of a multitasking cost when they multitask. The problem is that when they multitask. The problem is that when they multitask. The problem is that other studies show they're also more other studies show they're also more other studies show they're also more distractable because their brains have distractable because their brains have distractable because their brains have learned to stop filtering out learned to stop filtering out learned to stop filtering out information from the periphery because information from the periphery because information from the periphery because they're trying to attend to multiple they're trying to attend to multiple they're trying to attend to multiple things at the same time. So, and then things at the same time. So, and then things at the same time. So, and then the result is that we're we're the result is that we're we're the result is that we're we're distracted, right? And distracted, right? And distracted, right? And >> it it impairs the ability to actually do >> it it impairs the ability to actually do >> it it impairs the ability to actually do the deep work. Exactly. Because you're the deep work. Exactly. Because you're the deep work. Exactly. Because you're not acclimated to it. not acclimated to it. not acclimated to it. >> Yeah. But this is again it's just the >> Yeah. But this is again it's just the >> Yeah. But this is again it's just the brain responding uh to the stimulus, brain responding uh to the stimulus, brain responding uh to the stimulus, right? you're training it to do this and right? you're training it to do this and right? you're training it to do this and it gets better at this, but there's a it gets better at this, but there's a it gets better at this, but there's a trade-off, right? Just if you want to be trade-off, right? Just if you want to be trade-off, right? Just if you want to be an elite level marathon runner, you're an elite level marathon runner, you're an elite level marathon runner, you're not going to be a super heavyweight not going to be a super heavyweight not going to be a super heavyweight powerlifter at the same time, right? And powerlifter at the same time, right? And powerlifter at the same time, right? And this is the brain, like you're training this is the brain, like you're training this is the brain, like you're training it to multitask. So therefore, it's less it to multitask. So therefore, it's less it to multitask. So therefore, it's less good at deep focused um like attention good at deep focused um like attention good at deep focused um like attention driving work. driving work. driving work. >> So then it comes down to how are we >> So then it comes down to how are we >> So then it comes down to how are we using these tools? How are we using using these tools? How are we using using these tools? How are we using technology? And right the other example technology? And right the other example technology? And right the other example that would would is going to come up that would would is going to come up that would would is going to come up just like you kind of mentioned is is AI just like you kind of mentioned is is AI just like you kind of mentioned is is AI right right right >> anything we say about AI is probably >> anything we say about AI is probably >> anything we say about AI is probably going to be completely obsolete in in in going to be completely obsolete in in in going to be completely obsolete in in in two in two months time um but I think two in two months time um but I think two in two months time um but I think again we can there's like a framework again we can there's like a framework again we can there's like a framework that we can that we can use um and this that we can that we can use um and this that we can that we can use um and this was some of this stuff is proposed more was some of this stuff is proposed more was some of this stuff is proposed more than a decade ago by um a colleague of than a decade ago by um a colleague of than a decade ago by um a colleague of mine called Ken Ford who's an expert in mine called Ken Ford who's an expert in mine called Ken Ford who's an expert in AI and like back when AI wasn't even a AI and like back when AI wasn't even a AI and like back when AI wasn't even a thing he talks about this idea of thing he talks about this idea of thing he talks about this idea of cognitive prosthetics cognitive prosthetics cognitive prosthetics versus cognitive orthotics. An orthotic versus cognitive orthotics. An orthotic versus cognitive orthotics. An orthotic is something that you use to enhance or is something that you use to enhance or is something that you use to enhance or support your current levels of ability. support your current levels of ability. support your current levels of ability. Right? So when I think about orthotics, Right? So when I think about orthotics, Right? So when I think about orthotics, I think about um shoes for individuals I think about um shoes for individuals I think about um shoes for individuals with cerebal palsy, right? If because with cerebal palsy, right? If because with cerebal palsy, right? If because of, you know, issues with motor control, of, you know, issues with motor control, of, you know, issues with motor control, they're unable to walk, but you give they're unable to walk, but you give they're unable to walk, but you give them the right orthotic, they can walk. them the right orthotic, they can walk. them the right orthotic, they can walk. You've enhanced their capacity. Um You've enhanced their capacity. Um You've enhanced their capacity. Um whereas you use a pro a prosthetic to whereas you use a pro a prosthetic to whereas you use a pro a prosthetic to replace something that you don't have. replace something that you don't have. replace something that you don't have. You have a prosthetic leg because you're You have a prosthetic leg because you're You have a prosthetic leg because you're missing part or whole of your leg. We missing part or whole of your leg. We missing part or whole of your leg. We are at risk of using AI as a prosthetic are at risk of using AI as a prosthetic are at risk of using AI as a prosthetic instead of our brain as if we didn't instead of our brain as if we didn't instead of our brain as if we didn't have one. And we know that when we don't have one. And we know that when we don't have one. And we know that when we don't continue to engage those skills or continue to engage those skills or continue to engage those skills or things that you know we're using AI to things that you know we're using AI to things that you know we're using AI to do for us, we will lose those functions do for us, we will lose those functions do for us, we will lose those functions or we'll never develop them in the first or we'll never develop them in the first or we'll never develop them in the first place. Um but we could use these tools place. Um but we could use these tools place. Um but we could use these tools as a as an orthotic. We could say um we as a as an orthotic. We could say um we as a as an orthotic. We could say um we do the work ourselves, right? And there do the work ourselves, right? And there do the work ourselves, right? And there are some initial studies on this with uh are some initial studies on this with uh are some initial studies on this with uh students writing essays. This is one students writing essays. This is one students writing essays. This is one study that sort of like blew up the study that sort of like blew up the study that sort of like blew up the internet uh was an essay writing study internet uh was an essay writing study internet uh was an essay writing study at MIT. at MIT. at MIT. >> So the the students who ended up doing >> So the the students who ended up doing >> So the the students who ended up doing the best with the with were were the the best with the with were were the the best with the with were were the students who wrote the essay first students who wrote the essay first students who wrote the essay first themselves and then afterwards they got themselves and then afterwards they got themselves and then afterwards they got access to an AI tool. Um, and then it's access to an AI tool. Um, and then it's access to an AI tool. Um, and then it's then you're saying, you know, how can I then you're saying, you know, how can I then you're saying, you know, how can I improve this? What can I do better? What improve this? What can I do better? What improve this? What can I do better? What what have I never thought about? What what have I never thought about? What what have I never thought about? What have I missed? And then you take that have I missed? And then you take that have I missed? And then you take that information and you integrate it back in information and you integrate it back in information and you integrate it back in yourself, right? So, all of that yourself, right? So, all of that yourself, right? So, all of that requires you to do the work. It requires requires you to do the work. It requires requires you to do the work. It requires you to be engaged.

Uh and I think we just sort of were. Uh and I think we just sort of were. Uh and I think we just sort of assume well we're just you know we just assume well we're just you know we just assume well we're just you know we just you know it just becomes harder and you know it just becomes harder and you know it just becomes harder and harder to learn new things but harder to learn new things but harder to learn new things but essentially what you're saying is uh not essentially what you're saying is uh not essentially what you're saying is uh not only can we do that it's urgent that we only can we do that it's urgent that we only can we do that it's urgent that we are always kind of engaged in that are always kind of engaged in that are always kind of engaged in that process. process. process. >> Absolutely.

And essentially become useless, right? And essentially become useless, right? And we're unable to learn new things. We we're unable to learn new things. We we're unable to learn new things. We need to be put out to pasture, right? need to be put out to pasture, right? need to be put out to pasture, right? That was that was how retirement was That was that was how retirement was That was that was how retirement was framed when it was first popularized framed when it was first popularized framed when it was first popularized back in the beginning of the 20th back in the beginning of the 20th back in the beginning of the 20th century was by the time you're 60, century was by the time you're 60, century was by the time you're 60, you're essentially you have no use to you're essentially you have no use to you're essentially you have no use to society, so we just have to like find a society, so we just have to like find a society, so we just have to like find a corner to stick you in. And we've corner to stick you in. And we've corner to stick you in. And we've embodied that as a society. And embodied that as a society. And embodied that as a society. And therefore, this is something that we therefore, this is something that we therefore, this is something that we expect, right? There's this idea of expect, right? There's this idea of expect, right? There's this idea of stereotype embodiment theory, which is stereotype embodiment theory, which is stereotype embodiment theory, which is that if we expect aging to be associated that if we expect aging to be associated that if we expect aging to be associated with a significant loss of physical and with a significant loss of physical and with a significant loss of physical and cognitive function, we will know we we cognitive function, we will know we we cognitive function, we will know we we stop engaging with the things that stop engaging with the things that stop engaging with the things that maintain physical and cognitive maintain physical and cognitive maintain physical and cognitive function.

And it becomes a vicious cycle. Exactly. So what you see is that even in Exactly. So what you see is that even in Exactly. So what you see is that even in people in their 60s, 70s, 80s, when you people in their 60s, 70s, 80s, when you people in their 60s, 70s, 80s, when you do a randomized control trial of do a randomized control trial of do a randomized control trial of language learning or music learning or language learning or music learning or language learning or music learning or physical activity, you can see physical activity, you can see physical activity, you can see structural changes in the brain. You can structural changes in the brain. You can structural changes in the brain. You can you can measure improvements in you can measure improvements in you can measure improvements in cognitive function. The brain is still cognitive function. The brain is still cognitive function. The brain is still plastic at those ages. It's true that plastic at those ages. It's true that plastic at those ages. It's true that learning is is potentially slightly learning is is potentially slightly learning is is potentially slightly harder and takes a little longer than harder and takes a little longer than harder and takes a little longer than when you're very young, but that's not when you're very young, but that's not when you're very young, but that's not because the adult brain isn't capable of because the adult brain isn't capable of because the adult brain isn't capable of change. It's because you have shaped change. It's because you have shaped change. It's because you have shaped your brain to uh allow you to best your brain to uh allow you to best your brain to uh allow you to best function in the environment that you've function in the environment that you've function in the environment that you've put it in. Right? So, you don't want it put it in. Right? So, you don't want it put it in. Right? So, you don't want it to be like really really malleable to be like really really malleable to be like really really malleable because it's already become the person because it's already become the person because it's already become the person that you are, right? And that's what that you are, right? And that's what that you are, right? And that's what that's what you want. So, it's capable that's what you want. So, it's capable that's what you want. So, it's capable of change. You just have to engage in of change. You just have to engage in of change. You just have to engage in the processes that drive change. Show the processes that drive change. Show the processes that drive change. Show your brain that it matters. And the way your brain that it matters. And the way your brain that it matters. And the way the way to do that is by truly focusing the way to do that is by truly focusing the way to do that is by truly focusing on something. Um and then that that on something. Um and then that that on something. Um and then that that change will happen. We can measure change will happen. We can measure change will happen. We can measure changes in both the structure and the changes in both the structure and the changes in both the structure and the function of the brain um in regions that function of the brain um in regions that function of the brain um in regions that are susceptible to the processes of are susceptible to the processes of are susceptible to the processes of aging that um become dysfunctional or aging that um become dysfunctional or aging that um become dysfunctional or lose volume in the processes of of uh lose volume in the processes of of uh lose volume in the processes of of uh dementia. So we can see even late in dementia. So we can see even late in dementia. So we can see even late in life we can change that trajectory if we life we can change that trajectory if we life we can change that trajectory if we engage in these different you know true engage in these different you know true engage in these different you know true sort of cognitive stimuli. sort of cognitive stimuli. sort of cognitive stimuli. >> Yeah.

I didn't get that right. I need second. I didn't get that right. I need second. I didn't get that right. I need to create new connections. I need to to create new connections. I need to to create new connections. I need to shape something differently in order to shape something differently in order to shape something differently in order to improve my prediction in in the future." improve my prediction in in the future." improve my prediction in in the future." And we see this from um learning And we see this from um learning And we see this from um learning research as well, like what helps uh research as well, like what helps uh research as well, like what helps uh people learn faster. And one of one of people learn faster. And one of one of people learn faster. And one of one of the most important things is making the most important things is making the most important things is making mistakes, is making errors because it mistakes, is making errors because it mistakes, is making errors because it drives those processes. That's why you drives those processes. That's why you drives those processes. That's why you know a lot of neuroplasticity is driven know a lot of neuroplasticity is driven know a lot of neuroplasticity is driven by neurotransmitters like uh by neurotransmitters like uh by neurotransmitters like uh noradrenaline um and dopamine you and noradrenaline um and dopamine you and noradrenaline um and dopamine you and these are catacolamines. These are these are catacolamines. These are these are catacolamines. These are stress hormones right so it feels stress hormones right so it feels stress hormones right so it feels slightly uncomfortable um and that's slightly uncomfortable um and that's slightly uncomfortable um and that's part of the point um this is your brain part of the point um this is your brain part of the point um this is your brain attending to something important and attending to something important and attending to something important and diverting resources to change and diverting resources to change and diverting resources to change and response. So what that means for us is response. So what that means for us is response. So what that means for us is that we have to do things that put us in that we have to do things that put us in that we have to do things that put us in a in a position to make mistakes or to a in a position to make mistakes or to a in a position to make mistakes or to fail occasionally, right? You don't you fail occasionally, right? You don't you fail occasionally, right? You don't you don't want to fail all the time because don't want to fail all the time because don't want to fail all the time because it becomes very demotivating. But it becomes very demotivating. But it becomes very demotivating. But somewhere where you can see progression, somewhere where you can see progression, somewhere where you can see progression, but occasionally you're sort of like but occasionally you're sort of like but occasionally you're sort of like pushing at the edges of your current pushing at the edges of your current pushing at the edges of your current capability because that's what drives capability because that's what drives capability because that's what drives neuroplasticity. But adults hate that, neuroplasticity. But adults hate that, neuroplasticity. But adults hate that, right? anytime you think about doing right? anytime you think about doing right? anytime you think about doing something like you go to a jiu-jitsu's something like you go to a jiu-jitsu's something like you go to a jiu-jitsu's class and you're like the bottom rung of class and you're like the bottom rung of class and you're like the bottom rung of the ladder and like people are gonna the ladder and like people are gonna the ladder and like people are gonna kick your ass and throw you over their kick your ass and throw you over their kick your ass and throw you over their shoulders and like you're worried about shoulders and like you're worried about shoulders and like you're worried about injury and all these other things or injury and all these other things or injury and all these other things or you're worried about looking stupid. Um you're worried about looking stupid. Um you're worried about looking stupid. Um but it's putting ourselves in those but it's putting ourselves in those but it's putting ourselves in those situations where we have the capacity to situations where we have the capacity to situations where we have the capacity to try fail learn go back again that's try fail learn go back again that's try fail learn go back again that's what's really driving um those changes what's really driving um those changes what's really driving um those changes in the brain. So we need to kind of lean in the brain. So we need to kind of lean in the brain. So we need to kind of lean into that discomfort. into that discomfort. into that discomfort. >> Yeah.

Uh how >> let's talk about exercise. Uh how >> let's talk about exercise. Uh how important is movement to brain health? important is movement to brain health? important is movement to brain health? Why is it so important? And how should Why is it so important? And how should Why is it so important? And how should we think about this? we think about this? we think about this? It's incredibly important and It's incredibly important and It's incredibly important and the the the sort of the most fundamental reason for sort of the most fundamental reason for sort of the most fundamental reason for that I think is that that I think is that that I think is that historically as a species we've moved a historically as a species we've moved a historically as a species we've moved a lot. Um and it's kind of like there's a lot. Um and it's kind of like there's a lot. Um and it's kind of like there's a there's a quote from an eigo san who there's a quote from an eigo san who there's a quote from an eigo san who says that right it's movement is says that right it's movement is says that right it's movement is evolutionary baked into our genes. It's evolutionary baked into our genes. It's evolutionary baked into our genes. It's like a requirement of our biology. If like a requirement of our biology. If like a requirement of our biology. If you want your brain and your body to you want your brain and your body to you want your brain and your body to function well, it needs to move function well, it needs to move function well, it needs to move frequently. If you think about sort of frequently. If you think about sort of frequently. If you think about sort of even just our recent ancestors were even just our recent ancestors were even just our recent ancestors were maybe walking 15 to 20,000 steps a day, maybe walking 15 to 20,000 steps a day, maybe walking 15 to 20,000 steps a day, they were moving 6 to 8 hours a day. Um, they were moving 6 to 8 hours a day. Um, they were moving 6 to 8 hours a day. Um, and it's essentially required just to and it's essentially required just to and it's essentially required just to keep maintenance and other cellular keep maintenance and other cellular keep maintenance and other cellular processes going in the body. And that processes going in the body. And that processes going in the body. And that includes in the brain. Um and so because includes in the brain. Um and so because includes in the brain. Um and so because we no longer have that, you know, just we no longer have that, you know, just we no longer have that, you know, just like we've um sort of engineered the like we've um sort of engineered the like we've um sort of engineered the food environment in a way that means we food environment in a way that means we food environment in a way that means we have to invent diets, we've engineered have to invent diets, we've engineered have to invent diets, we've engineered the phys the built environment such such the phys the built environment such such the phys the built environment such such that we now have to invent exercise. And that we now have to invent exercise. And that we now have to invent exercise. And now I think we're getting to the point now I think we're getting to the point now I think we're getting to the point where we've engineered the cognitive where we've engineered the cognitive where we've engineered the cognitive environment such that we now have to environment such that we now have to environment such that we now have to invent new stimuli, right? That's kind invent new stimuli, right? That's kind invent new stimuli, right? That's kind of like the next frontier. But we know of like the next frontier. But we know of like the next frontier. But we know uh that different types of movement uh that different types of movement uh that different types of movement actually have different effects on the actually have different effects on the actually have different effects on the brain. So even just breaking up periods brain. So even just breaking up periods brain. So even just breaking up periods of being sedentary um what we might call of being sedentary um what we might call of being sedentary um what we might call exercise snacks um can immediately and exercise snacks um can immediately and exercise snacks um can immediately and boo uh boost mood. It uh changes blood boo uh boost mood. It uh changes blood boo uh boost mood. It uh changes blood flow to the brain can immediately change flow to the brain can immediately change flow to the brain can immediately change cognitive function. Um so just starting cognitive function. Um so just starting cognitive function. Um so just starting with regular low-level periods of with regular low-level periods of with regular low-level periods of movement during the day we already we movement during the day we already we movement during the day we already we already see an impact and we know that already see an impact and we know that already see an impact and we know that the sort of like number of steps that the sort of like number of steps that the sort of like number of steps that you have in a day and it could be right you have in a day and it could be right you have in a day and it could be right if you if you don't if you don't walk if you if you don't if you don't walk if you if you don't if you don't walk and some people some people can't walk and some people some people can't walk and some people some people can't walk it could be like propelling a wheelchair it could be like propelling a wheelchair it could be like propelling a wheelchair around or like however you get about the around or like however you get about the around or like however you get about the world right as as that increases up to world right as as that increases up to world right as as that increases up to sort of the equivalent of 8 to 12,000 sort of the equivalent of 8 to 12,000 sort of the equivalent of 8 to 12,000 steps a day you see a linear reduction steps a day you see a linear reduction steps a day you see a linear reduction in risk of dementia and a linear in risk of dementia and a linear in risk of dementia and a linear increase in cog in cognitive function. increase in cog in cognitive function. increase in cog in cognitive function. From there, we know that sort of aerobic From there, we know that sort of aerobic From there, we know that sort of aerobic type movement. So, now if we're getting type movement. So, now if we're getting type movement. So, now if we're getting into brisk walking, jogging, cycling, into brisk walking, jogging, cycling, into brisk walking, jogging, cycling, this seems to be particularly good for this seems to be particularly good for this seems to be particularly good for memory function um and the structure uh memory function um and the structure uh memory function um and the structure uh and of the gray matter. So, like if you and of the gray matter. So, like if you and of the gray matter. So, like if you think about the brain, it's this big think about the brain, it's this big think about the brain, it's this big wrinkly sort of fatty ball and the the wrinkly sort of fatty ball and the the wrinkly sort of fatty ball and the the the outer part is the is the cortex is the outer part is the is the cortex is the outer part is the is the cortex is the gray matter and then there's more the gray matter and then there's more the gray matter and then there's more gray matter inside. Um, part of that is gray matter inside. Um, part of that is gray matter inside. Um, part of that is the hippocampus, which we know is really the hippocampus, which we know is really the hippocampus, which we know is really important for memory and is particularly important for memory and is particularly important for memory and is particularly susceptible in the later stages of of susceptible in the later stages of of susceptible in the later stages of of Alzheimer's disease. And so, uh, we know Alzheimer's disease. And so, uh, we know Alzheimer's disease. And so, uh, we know that people who regularly do something that people who regularly do something that people who regularly do something like brisk walking, they can like brisk walking, they can like brisk walking, they can significantly improve the structure and significantly improve the structure and significantly improve the structure and function of of the hippocampus. function of of the hippocampus. function of of the hippocampus. >> There was a more recent study, uh, that >> There was a more recent study, uh, that >> There was a more recent study, uh, that that kind of told us that intensity is that kind of told us that intensity is that kind of told us that intensity is also important. So, some of the things also important. So, some of the things also important. So, some of the things that get released during exercise, I that get released during exercise, I that get released during exercise, I mentioned brain derived neurotrophic mentioned brain derived neurotrophic mentioned brain derived neurotrophic factor earlier. there are, you know, factor earlier. there are, you know, factor earlier. there are, you know, dozens of of miaakines or exacins that dozens of of miaakines or exacins that dozens of of miaakines or exacins that get released, many of which can impact get released, many of which can impact get released, many of which can impact the brain, but they're released in an the brain, but they're released in an the brain, but they're released in an intensity dependent manner. So, there intensity dependent manner. So, there intensity dependent manner. So, there was another recent study uh in was another recent study uh in was another recent study uh in individuals in their 60s and 70s. They individuals in their 60s and 70s. They individuals in their 60s and 70s. They randomized them into three groups. They randomized them into three groups. They randomized them into three groups. They had like a control group, they had a a had like a control group, they had a a had like a control group, they had a a sort of like a zone 2, low zone 3-ish sort of like a zone 2, low zone 3-ish sort of like a zone 2, low zone 3-ish sort of jogging kind of group, and then sort of jogging kind of group, and then sort of jogging kind of group, and then they had a high intensity interval they had a high intensity interval they had a high intensity interval training group. And for 6 months, three training group. And for 6 months, three training group. And for 6 months, three times a week, they did 40 to 45 minutes times a week, they did 40 to 45 minutes times a week, they did 40 to 45 minutes of their chosen exercise. Um the the HIT of their chosen exercise. Um the the HIT of their chosen exercise. Um the the HIT group did the Norwegian 4x4 protocol. Um group did the Norwegian 4x4 protocol. Um group did the Norwegian 4x4 protocol. Um so for those who aren't familiar, it's 4 so for those who aren't familiar, it's 4 so for those who aren't familiar, it's 4 minutes of running at 85 to 95% of minutes of running at 85 to 95% of minutes of running at 85 to 95% of maximum heart rate. In this study, they maximum heart rate. In this study, they maximum heart rate. In this study, they had a 3minut rest in between. Some had a 3minut rest in between. Some had a 3minut rest in between. Some studies have four minutes, some studies studies have four minutes, some studies studies have four minutes, some studies have 5 minutes. I don't think it matters have 5 minutes. I don't think it matters have 5 minutes. I don't think it matters that much. Um and then they do that four that much. Um and then they do that four that much. Um and then they do that four times over. And they did that three times over. And they did that three times over. And they did that three times a week for six months. times a week for six months. times a week for six months. >> Mhm. And interestingly, what they found >> Mhm. And interestingly, what they found >> Mhm. And interestingly, what they found was that both the sort of the jogging was that both the sort of the jogging was that both the sort of the jogging group and the HIT group improved group and the HIT group improved group and the HIT group improved cardiovascular fitness by the same cardiovascular fitness by the same cardiovascular fitness by the same amount. Um, but the HIT group had much amount. Um, but the HIT group had much amount. Um, but the HIT group had much greater improvements in the structure greater improvements in the structure greater improvements in the structure and function of the hippocampus. Um, and and function of the hippocampus. Um, and and function of the hippocampus. Um, and so they they did much better on a so they they did much better on a so they they did much better on a learning task and that benefit was learning task and that benefit was learning task and that benefit was retained for 5 years. They went back retained for 5 years. They went back retained for 5 years. They went back five years later and they still had u five years later and they still had u five years later and they still had u maintained improvement even though maintained improvement even though maintained improvement even though they'd gone back to their previous they'd gone back to their previous they'd gone back to their previous levels of exercise. they hadn't said, levels of exercise. they hadn't said, levels of exercise. they hadn't said, "Oh, I love sprint training, so I'm just "Oh, I love sprint training, so I'm just "Oh, I love sprint training, so I'm just going to do more of it." Um, they'd gone going to do more of it." Um, they'd gone going to do more of it." Um, they'd gone back to being relatively sedentary. And back to being relatively sedentary. And back to being relatively sedentary. And they still had benefits 5 years later. they still had benefits 5 years later. they still had benefits 5 years later. So, that's kind of on that spectrum of So, that's kind of on that spectrum of So, that's kind of on that spectrum of aerobic exercise up to sort of sprint aerobic exercise up to sort of sprint aerobic exercise up to sort of sprint training. Um, you see, um, across the training. Um, you see, um, across the training. Um, you see, um, across the entire spectrum, you see benefits. Um, entire spectrum, you see benefits. Um, entire spectrum, you see benefits. Um, but that type of exercise seems to but that type of exercise seems to but that type of exercise seems to particularly benefit the gray matter and particularly benefit the gray matter and particularly benefit the gray matter and and memory function uh largely by and memory function uh largely by and memory function uh largely by improving the uh the hippocampus or improving the uh the hippocampus or improving the uh the hippocampus or supporting the hippocampus. Then we supporting the hippocampus. Then we supporting the hippocampus. Then we might think about resistance training. might think about resistance training. might think about resistance training. Um, and what we see with resistance Um, and what we see with resistance Um, and what we see with resistance training is that it seems to training is that it seems to training is that it seems to particularly benefit the structure and particularly benefit the structure and particularly benefit the structure and function of the white matter. So the function of the white matter. So the function of the white matter. So the white matter sits underneath the gray white matter sits underneath the gray white matter sits underneath the gray matter. Um, and it's where all the matter. Um, and it's where all the matter. Um, and it's where all the myelin is, like all the sort of fat in myelin is, like all the sort of fat in myelin is, like all the sort of fat in the brain. And it's responsible for like the brain. And it's responsible for like the brain. And it's responsible for like the really fast connections. It's really the really fast connections. It's really the really fast connections. It's really important for, you know, com our complex important for, you know, com our complex important for, you know, com our complex cognitive functions like decision-m, cognitive functions like decision-m, cognitive functions like decision-m, executive function, that kind of stuff, executive function, that kind of stuff, executive function, that kind of stuff, which we know is lost even early on in which we know is lost even early on in which we know is lost even early on in the dementia process. the dementia process. the dementia process. and uh resistance training something and uh resistance training something and uh resistance training something like the studies they've done two times like the studies they've done two times like the studies they've done two times a week exercises like on which could be a week exercises like on which could be a week exercises like on which could be machines in the gym that cover the machines in the gym that cover the machines in the gym that cover the entire body you know five or six entire body you know five or six entire body you know five or six different exercises um three sets of different exercises um three sets of different exercises um three sets of eight to 12 reps a very basic resistance eight to 12 reps a very basic resistance eight to 12 reps a very basic resistance training program um twice a week for 6 training program um twice a week for 6 training program um twice a week for 6 months significantly improves the months significantly improves the months significantly improves the structure and function of the white structure and function of the white structure and function of the white matter so improved executive function matter so improved executive function matter so improved executive function and other things and you can see the and other things and you can see the and other things and you can see the changes on an MRI scan then the final changes on an MRI scan then the final changes on an MRI scan then the final piece uh when it comes to exercises is piece uh when it comes to exercises is piece uh when it comes to exercises is like these complex like these complex like these complex um movements um that we might call um movements um that we might call um movements um that we might call coordinative exercise or um open skill coordinative exercise or um open skill coordinative exercise or um open skill exercise is often what they call it in exercise is often what they call it in exercise is often what they call it in the literature. So like a closed skill the literature. So like a closed skill the literature. So like a closed skill exercise is something like running or exercise is something like running or exercise is something like running or cycling like unimodal unidirectional. cycling like unimodal unidirectional. cycling like unimodal unidirectional. Whereas an open skill exercise is Whereas an open skill exercise is Whereas an open skill exercise is something like badminton or um a martial something like badminton or um a martial something like badminton or um a martial art that requires you to kind of learn art that requires you to kind of learn art that requires you to kind of learn complex motor patterns, respond to the complex motor patterns, respond to the complex motor patterns, respond to the environment, respond to other people, environment, respond to other people, environment, respond to other people, maybe strategize um you're trying to maybe strategize um you're trying to maybe strategize um you're trying to manipulate your opponent around a tennis manipulate your opponent around a tennis manipulate your opponent around a tennis court um and process information much court um and process information much court um and process information much more quickly. um which is um more quickly. um which is um more quickly. um which is um particularly important as we get older particularly important as we get older particularly important as we get older as processing speed tends to drop off as processing speed tends to drop off as processing speed tends to drop off but it is trainable if we're doing but it is trainable if we're doing but it is trainable if we're doing things that require us to rapidly things that require us to rapidly things that require us to rapidly process information and this seems to be process information and this seems to be process information and this seems to be the best way to support sort of overall the best way to support sort of overall the best way to support sort of overall cognitive function depending on which cognitive function depending on which cognitive function depending on which kind of meta analysis of the studies kind of meta analysis of the studies kind of meta analysis of the studies that you look at. Um, and so that stuff, that you look at. Um, and so that stuff, that you look at. Um, and so that stuff, like I said, ball sports, team sports, like I said, ball sports, team sports, like I said, ball sports, team sports, board sports, martial arts, dancing, uh, board sports, martial arts, dancing, uh, board sports, martial arts, dancing, uh, dancing is often like wins out across, dancing is often like wins out across, dancing is often like wins out across, you know, compared to almost any other you know, compared to almost any other you know, compared to almost any other activity in terms of supporting both activity in terms of supporting both activity in terms of supporting both mental health and cognitive function. mental health and cognitive function. mental health and cognitive function. Um, so to then kind of like fit all that Um, so to then kind of like fit all that Um, so to then kind of like fit all that stuff together, um, we can think about stuff together, um, we can think about stuff together, um, we can think about just like just moving regularly just like just moving regularly just like just moving regularly throughout the day, doesn't have to be throughout the day, doesn't have to be throughout the day, doesn't have to be particularly intense, just to kind of particularly intense, just to kind of particularly intense, just to kind of break up extended periods of sitting. um break up extended periods of sitting. um break up extended periods of sitting. um if we can make our sort of aerobic type if we can make our sort of aerobic type if we can make our sort of aerobic type training um something that has a training um something that has a training um something that has a coordinative component right so it's a coordinative component right so it's a coordinative component right so it's a and especially if it has a social part and especially if it has a social part and especially if it has a social part right so rather than just going jogging right so rather than just going jogging right so rather than just going jogging maybe you uh play soccer or you play maybe you uh play soccer or you play maybe you uh play soccer or you play babon or even like table tennis um then babon or even like table tennis um then babon or even like table tennis um then I think you can get some additional I think you can get some additional I think you can get some additional additional benefits there um plus maybe additional benefits there um plus maybe additional benefits there um plus maybe once or twice a week you do some kind of once or twice a week you do some kind of once or twice a week you do some kind of resistance training once or twi twice a resistance training once or twi twice a resistance training once or twi twice a week you do some kind of sprint training week you do some kind of sprint training week you do some kind of sprint training meaning where um essentially you're just meaning where um essentially you're just meaning where um essentially you're just the the goal really is to generate the the goal really is to generate the the goal really is to generate lactate. Um lactate goes into the brain, lactate. Um lactate goes into the brain, lactate. Um lactate goes into the brain, switches on production of brain derived switches on production of brain derived switches on production of brain derived neurotrophic factor. And so it doesn't neurotrophic factor. And so it doesn't neurotrophic factor. And so it doesn't really matter what you do. It's just really matter what you do. It's just really matter what you do. It's just something that you know gets the heart something that you know gets the heart something that you know gets the heart rate up. You feel the burn a bit. Um and rate up. You feel the burn a bit. Um and rate up. You feel the burn a bit. Um and that could be even part of that could be that could be even part of that could be that could be even part of that could be part of your coordinates sites, right? part of your coordinates sites, right? part of your coordinates sites, right? You could you you get a lot of stopping You could you you get a lot of stopping You could you you get a lot of stopping and starting and sprinting in in some and starting and sprinting in in some and starting and sprinting in in some things like you know badminton or things like you know badminton or things like you know badminton or tennis, but something like that. So tennis, but something like that. So tennis, but something like that. So regular movement um you know some regular movement um you know some regular movement um you know some aerobic sessions being that kind of aerobic sessions being that kind of aerobic sessions being that kind of complex coordinative movement and then complex coordinative movement and then complex coordinative movement and then once or twice a week you do some kind of once or twice a week you do some kind of once or twice a week you do some kind of more intense you know sprinting a few more intense you know sprinting a few more intense you know sprinting a few times and and some kind of basic times and and some kind of basic times and and some kind of basic resistance training program that kind of resistance training program that kind of resistance training program that kind of hits all of those things based on what hits all of those things based on what hits all of those things based on what we know. Um even late in life can we know. Um even late in life can we know. Um even late in life can significantly uh improve and maintain significantly uh improve and maintain significantly uh improve and maintain brain function. brain function. brain function. >> Essentially what you're saying is it's a >> Essentially what you're saying is it's a >> Essentially what you're saying is it's a yes and approach. It's a it's a buffet. yes and approach. It's a it's a buffet. yes and approach. It's a it's a buffet. It's not about, you know, the Norwegian, It's not about, you know, the Norwegian, It's not about, you know, the Norwegian, you know, protocol necessarily. That's you know, protocol necessarily. That's you know, protocol necessarily. That's one piece and a larger hole that one piece and a larger hole that one piece and a larger hole that encompasses every, you know, kind of encompasses every, you know, kind of encompasses every, you know, kind of form of exercise that's, you know, form of exercise that's, you know, form of exercise that's, you know, driving you effectively forward. So, driving you effectively forward. So, driving you effectively forward. So, aerobic exercise, resistance training, aerobic exercise, resistance training, aerobic exercise, resistance training, dynam dynamic movements, and dynam dynamic movements, and dynam dynamic movements, and highintensity work, right? And finding a highintensity work, right? And finding a highintensity work, right? And finding a balance and and then the very kind of balance and and then the very kind of balance and and then the very kind of like low output walking, you know, type like low output walking, you know, type like low output walking, you know, type of activity. Uh all of these things are of activity. Uh all of these things are of activity. Uh all of these things are important for different reasons that important for different reasons that important for different reasons that that impact the brain in different ways that impact the brain in different ways that impact the brain in different ways and if you want to be as comprehensively and if you want to be as comprehensively and if you want to be as comprehensively brain healthy as possible, you have to brain healthy as possible, you have to brain healthy as possible, you have to uh you know attune yourself to all of uh you know attune yourself to all of uh you know attune yourself to all of these different forms of activity. these different forms of activity. these different forms of activity. >> Yeah, there's a there's a couple of >> Yeah, there's a there's a couple of >> Yeah, there's a there's a couple of important takeaways there. One, um first important takeaways there. One, um first important takeaways there. One, um first it's worth mentioning that uh we want as it's worth mentioning that uh we want as it's worth mentioning that uh we want as much as possible, we want to avoid this much as possible, we want to avoid this much as possible, we want to avoid this kind of like medical what Daniel Leeman kind of like medical what Daniel Leeman kind of like medical what Daniel Leeman calls the medicalization of exercise, calls the medicalization of exercise, calls the medicalization of exercise, right? right? right? And this happens when I I site a And this happens when I I site a And this happens when I I site a specific study and you're like, "Oh, specific study and you're like, "Oh, specific study and you're like, "Oh, well then I have to do Norwegian 4x4 well then I have to do Norwegian 4x4 well then I have to do Norwegian 4x4 like to benefit my brain." But like like to benefit my brain." But like like to benefit my brain." But like that's not that's not the case at all. that's not that's not the case at all. that's not that's not the case at all. It's It's It's >> there's a lot of confusion around >> there's a lot of confusion around >> there's a lot of confusion around Norwegian 4x4. It it and it all tracks Norwegian 4x4. It it and it all tracks Norwegian 4x4. It it and it all tracks back to our, you know, our our back to our, you know, our our back to our, you know, our our deep-seated need to, you know, reduce deep-seated need to, you know, reduce deep-seated need to, you know, reduce these things down to like a little these things down to like a little these things down to like a little nugget that I can remember. I mean, you nugget that I can remember. I mean, you nugget that I can remember. I mean, you were a rower, right? So, were a rower, right? So, were a rower, right? So, >> as a swimmer, any as any track and field >> as a swimmer, any as any track and field >> as a swimmer, any as any track and field athlete or rower or swimmer can tell athlete or rower or swimmer can tell athlete or rower or swimmer can tell you, you do all kinds of interval work. you, you do all kinds of interval work. you, you do all kinds of interval work. You're always varying, you know, that You're always varying, you know, that You're always varying, you know, that program. And I think the Norwegian 4x4 program. And I think the Norwegian 4x4 program. And I think the Norwegian 4x4 is a is an effective like uh, you know, is a is an effective like uh, you know, is a is an effective like uh, you know, interval modality, but interval modality, but interval modality, but >> there's many more that and and once you >> there's many more that and and once you >> there's many more that and and once you acclimate to that, then you you need to acclimate to that, then you you need to acclimate to that, then you you need to change it up, right? or you're not change it up, right? or you're not change it up, right? or you're not actually stimulating your physical body actually stimulating your physical body actually stimulating your physical body in the way that you could be if you're in the way that you could be if you're in the way that you could be if you're changing the structure of those interval changing the structure of those interval changing the structure of those interval workouts. workouts. workouts. >> Yeah. Exactly. And and so I think if we >> Yeah. Exactly. And and so I think if we >> Yeah. Exactly. And and so I think if we just think about the physiological just think about the physiological just think about the physiological response to that kind of thing, heart response to that kind of thing, heart response to that kind of thing, heart rate goes up, you release lactate, it's rate goes up, you release lactate, it's rate goes up, you release lactate, it's kind of like you're at that high level kind of like you're at that high level kind of like you're at that high level of intensity, you have rest periods in of intensity, you have rest periods in of intensity, you have rest periods in between. So you work hard for a short between. So you work hard for a short between. So you work hard for a short period of time, you rest in between. period of time, you rest in between. period of time, you rest in between. That's essentially it. You're going to That's essentially it. You're going to That's essentially it. You're going to be driving those those physiological be driving those those physiological be driving those those physiological responses. if people need like specific responses. if people need like specific responses. if people need like specific protocols like I I provide several in protocols like I I provide several in protocols like I I provide several in the book that have evidence behind them the book that have evidence behind them the book that have evidence behind them but in reality it's just move really but in reality it's just move really but in reality it's just move really really quickly rest a bit um that's really quickly rest a bit um that's really quickly rest a bit um that's going to be you're driving those going to be you're driving those going to be you're driving those functions um then the the the other functions um then the the the other functions um then the the the other thing to kind of take away is that there thing to kind of take away is that there thing to kind of take away is that there are sort of these core um principles are sort of these core um principles are sort of these core um principles across all these different types of across all these different types of across all these different types of activity but how you choose to do that activity but how you choose to do that activity but how you choose to do that is entirely up to you um because you'll is entirely up to you um because you'll is entirely up to you um because you'll get similar benefits from dancing or get similar benefits from dancing or get similar benefits from dancing or bminton or um even your martial arts bminton or um even your martial arts bminton or um even your martial arts jiu-jitsu right because it is doing all jiu-jitsu right because it is doing all jiu-jitsu right because it is doing all those same things in terms of like the those same things in terms of like the those same things in terms of like the pathways it's activating. So you can pathways it's activating. So you can pathways it's activating. So you can pick one that you enjoy and you want to pick one that you enjoy and you want to pick one that you enjoy and you want to get better at. And so like you said it get better at. And so like you said it get better at. And so like you said it is a smorggas board and you get to pick is a smorggas board and you get to pick is a smorggas board and you get to pick and choose and choose and choose >> but don't enjoy it too much or you're >> but don't enjoy it too much or you're >> but don't enjoy it too much or you're going to get stuck there, right? Like going to get stuck there, right? Like going to get stuck there, right? Like that's the thing with me like you know that's the thing with me like you know that's the thing with me like you know do I really want to you know play pickle do I really want to you know play pickle do I really want to you know play pickle ball? No. I I want to go do the thing ball? No. I I want to go do the thing ball? No. I I want to go do the thing that I know how to do. You know what I that I know how to do. You know what I that I know how to do. You know what I mean? I don't want to you know I don't mean? I don't want to you know I don't mean? I don't want to you know I don't want to be bad. want to be bad. want to be bad. >> Yeah. Yeah. So, so then of course we go >> Yeah. Yeah. So, so then of course we go >> Yeah. Yeah. So, so then of course we go back to the previous thing which is you back to the previous thing which is you back to the previous thing which is you try and find something maybe where try and find something maybe where try and find something maybe where you've got some something to learn. you've got some something to learn. you've got some something to learn. You're going to you sort of You're going to you sort of You're going to you sort of >> lean into that little bit of discomfort >> lean into that little bit of discomfort >> lean into that little bit of discomfort especially in the complex coordinative especially in the complex coordinative especially in the complex coordinative stuff because I think that's going to stuff because I think that's going to stuff because I think that's going to give you extra bang for your buck give you extra bang for your buck give you extra bang for your buck >> on the resistance training uh aspect of >> on the resistance training uh aspect of >> on the resistance training uh aspect of this. Um there's a lot of discourse now this. Um there's a lot of discourse now this. Um there's a lot of discourse now around longevity extension and the around longevity extension and the around longevity extension and the importance of maintaining your muscle importance of maintaining your muscle importance of maintaining your muscle mass. So when you think about resistance mass. So when you think about resistance mass. So when you think about resistance training, what's more important? Muscle training, what's more important? Muscle training, what's more important? Muscle mass or is it functional strength? How mass or is it functional strength? How mass or is it functional strength? How do you parse those two ideas? do you parse those two ideas? do you parse those two ideas? In general, your strength is In general, your strength is In general, your strength is proportional to your muscle mass. Um so proportional to your muscle mass. Um so proportional to your muscle mass. Um so when you're building one, you tend to when you're building one, you tend to when you're building one, you tend to build the other. As we get older, um build the other. As we get older, um build the other. As we get older, um often you train strength more than you often you train strength more than you often you train strength more than you train muscle mass. But in reality, what train muscle mass. But in reality, what train muscle mass. But in reality, what you want is to sort of like the the sort you want is to sort of like the the sort you want is to sort of like the the sort of like the the immediate benefits like of like the the immediate benefits like of like the the immediate benefits like just like moving your having having just like moving your having having just like moving your having having muscle and moving it, right? We release muscle and moving it, right? We release muscle and moving it, right? We release things that go and support support the things that go and support support the things that go and support support the brain. It's important for blood sugar brain. It's important for blood sugar brain. It's important for blood sugar regulation. Our muscles are our biggest regulation. Our muscles are our biggest regulation. Our muscles are our biggest like blood sugar sync for most people. I like blood sugar sync for most people. I like blood sugar sync for most people. I think that any kind of resistance think that any kind of resistance think that any kind of resistance training is going to get you both at the training is going to get you both at the training is going to get you both at the same time. When there are some same time. When there are some same time. When there are some interesting like population studies interesting like population studies interesting like population studies where they look at strength and they where they look at strength and they where they look at strength and they look at muscle mass and they look at the look at muscle mass and they look at the look at muscle mass and they look at the relationship to dementia or heart relationship to dementia or heart relationship to dementia or heart disease risk or mortality risk and what disease risk or mortality risk and what disease risk or mortality risk and what you see is that at high levels of muscle you see is that at high levels of muscle you see is that at high levels of muscle mass you almost start to see risk mass you almost start to see risk mass you almost start to see risk increase again. Um so what so like there increase again. Um so what so like there increase again. Um so what so like there are some there have been some studies are some there have been some studies are some there have been some studies out there that say that at very high out there that say that at very high out there that say that at very high levels of muscle mass you have a higher levels of muscle mass you have a higher levels of muscle mass you have a higher risk of cardiovascular disease a higher risk of cardiovascular disease a higher risk of cardiovascular disease a higher risk of um all cause mortality. risk of um all cause mortality. risk of um all cause mortality. The problem is that those studies don't The problem is that those studies don't The problem is that those studies don't determine how you gained that muscle determine how you gained that muscle determine how you gained that muscle mass in the first place. So if you gain mass in the first place. So if you gain mass in the first place. So if you gain that muscle mass through resistance that muscle mass through resistance that muscle mass through resistance training and exercise, your muscle mass training and exercise, your muscle mass training and exercise, your muscle mass increases in line with your strength. increases in line with your strength. increases in line with your strength. And we know that strength um you know at And we know that strength um you know at And we know that strength um you know at high levels of strength you don't have high levels of strength you don't have high levels of strength you don't have an increased risk of disease. Like the an increased risk of disease. Like the an increased risk of disease. Like the high the higher your strength the better high the higher your strength the better high the higher your strength the better essentially. essentially. essentially. >> So what you're seeing at the population >> So what you're seeing at the population >> So what you're seeing at the population level is that some people just gain more level is that some people just gain more level is that some people just gain more muscle mass because they've gained more muscle mass because they've gained more muscle mass because they've gained more total mass. But that's not functional total mass. But that's not functional total mass. But that's not functional muscle in the same way as that if as if muscle in the same way as that if as if muscle in the same way as that if as if that muscle was gained through that muscle was gained through that muscle was gained through resistance training if that makes sense. resistance training if that makes sense. resistance training if that makes sense. So, I think the the real kind of So, I think the the real kind of So, I think the the real kind of takeaway is building strength that's takeaway is building strength that's takeaway is building strength that's functional and provides relative functional and provides relative functional and provides relative strength for you. You just need to be strength for you. You just need to be strength for you. You just need to be strong enough for yourself relative to strong enough for yourself relative to strong enough for yourself relative to your own body size, whatever that body your own body size, whatever that body your own body size, whatever that body size is. Um, and so if you're, you know, size is. Um, and so if you're, you know, size is. Um, and so if you're, you know, larger or smaller, you would you would larger or smaller, you would you would larger or smaller, you would you would expect on average be um stronger um or expect on average be um stronger um or expect on average be um stronger um or if you're larger, you would expect if you're larger, you would expect if you're larger, you would expect expect to be stronger. if you're getting expect to be stronger. if you're getting expect to be stronger. if you're getting to the point where um you know you've to the point where um you know you've to the point where um you know you've gained a lot of a lot of muscle mass but gained a lot of a lot of muscle mass but gained a lot of a lot of muscle mass but it's not through exercise that muscle it's not through exercise that muscle it's not through exercise that muscle may not be functional in the same way. may not be functional in the same way. may not be functional in the same way. So the the easiest way to measure this So the the easiest way to measure this So the the easiest way to measure this to kind of like give a takeaway is that to kind of like give a takeaway is that to kind of like give a takeaway is that strength is probably more important than strength is probably more important than strength is probably more important than muscle mass. muscle mass. muscle mass. >> Um and when you work to improve your >> Um and when you work to improve your >> Um and when you work to improve your strength you will also improve muscle strength you will also improve muscle strength you will also improve muscle mass at the same at the same time. sort mass at the same at the same time. sort mass at the same at the same time. sort of like a final important particularly of like a final important particularly of like a final important particularly if we're thinking about as we getting if we're thinking about as we getting if we're thinking about as we getting older is you we we can measure multiple older is you we we can measure multiple older is you we we can measure multiple things. We can measure mus muscle muscle things. We can measure mus muscle muscle things. We can measure mus muscle muscle mass muscle strength. So like how much mass muscle strength. So like how much mass muscle strength. So like how much like the maximum you can uh lift but like the maximum you can uh lift but like the maximum you can uh lift but then also things like power. So like how then also things like power. So like how then also things like power. So like how fast can you how fast can you contract fast can you how fast can you contract fast can you how fast can you contract and and move your muscles and things and and move your muscles and things and and move your muscles and things like power are are lost the fastest. And like power are are lost the fastest. And like power are are lost the fastest. And that's important because when you lose that's important because when you lose that's important because when you lose the the the muscle fibers that are the the the muscle fibers that are the the the muscle fibers that are associated with greater strength and associated with greater strength and associated with greater strength and power, um that's where you stop being power, um that's where you stop being power, um that's where you stop being able to like stop yourself from tripping able to like stop yourself from tripping able to like stop yourself from tripping over or grabbing onto a handrail if over or grabbing onto a handrail if over or grabbing onto a handrail if you're about to fall down. And and we you're about to fall down. And and we you're about to fall down. And and we know then the the knock-on effect is hip know then the the knock-on effect is hip know then the the knock-on effect is hip fractures and spending a long time bed fractures and spending a long time bed fractures and spending a long time bed bound where you then lose even more bound where you then lose even more bound where you then lose even more physical and cognitive function. It's physical and cognitive function. It's physical and cognitive function. It's really hard to come back from that. So really hard to come back from that. So really hard to come back from that. So in addition to just like any kind of in addition to just like any kind of in addition to just like any kind of weightlifting I think which is going to weightlifting I think which is going to weightlifting I think which is going to improve strength um there's really improve strength um there's really improve strength um there's really interesting studies on like jumping in interesting studies on like jumping in interesting studies on like jumping in older adults just like a minute of older adults just like a minute of older adults just like a minute of jumping a day significantly improves jumping a day significantly improves jumping a day significantly improves like bone mass and and muscle strength like bone mass and and muscle strength like bone mass and and muscle strength and power. Um, so in addition to just and power. Um, so in addition to just and power. Um, so in addition to just like the kind of like say using weights like the kind of like say using weights like the kind of like say using weights in the gym, just finding something that in the gym, just finding something that in the gym, just finding something that requires you to jump, you know, uh, you requires you to jump, you know, uh, you requires you to jump, you know, uh, you could be skipping ropes, um, it could could be skipping ropes, um, it could could be skipping ropes, um, it could just be like jumping on the spot, just be like jumping on the spot, just be like jumping on the spot, jumping on one leg. We know those have jumping on one leg. We know those have jumping on one leg. We know those have additional benefits because you're additional benefits because you're additional benefits because you're maintaining some of those some of those maintaining some of those some of those maintaining some of those some of those elements of function that we know are elements of function that we know are elements of function that we know are going to be important. going to be important. going to be important. >> Yeah. Interesting. Um, yeah, if you are >> Yeah. Interesting. Um, yeah, if you are >> Yeah. Interesting. Um, yeah, if you are weightlifting like a bodybuilder, but weightlifting like a bodybuilder, but weightlifting like a bodybuilder, but you're not thinking about speed, you're not thinking about speed, you're not thinking about speed, acceleration, acceleration, acceleration, uh, or compound movements, like don't we uh, or compound movements, like don't we uh, or compound movements, like don't we sort of want to be like Ido Portal or, sort of want to be like Ido Portal or, sort of want to be like Ido Portal or, you know, take take Kelly Starret's you know, take take Kelly Starret's you know, take take Kelly Starret's advice and make sure that we're supple advice and make sure that we're supple advice and make sure that we're supple and able to, you know, bend in all the and able to, you know, bend in all the and able to, you know, bend in all the right ways and move quickly, laterally right ways and move quickly, laterally right ways and move quickly, laterally forward, backwards, and all these sorts forward, backwards, and all these sorts forward, backwards, and all these sorts of things that just a, you know, of things that just a, you know, of things that just a, you know, straight straightforward weightlifting, straight straightforward weightlifting, straight straightforward weightlifting, you know, and the tradition of you know, and the tradition of you know, and the tradition of bodybuilding, um, is really not going to bodybuilding, um, is really not going to bodybuilding, um, is really not going to do the trick. do the trick. do the trick. >> So, luckily, I I don't think those >> So, luckily, I I don't think those >> So, luckily, I I don't think those things are mutually exclusive. Actually, things are mutually exclusive. Actually, things are mutually exclusive. Actually, you know, doing even traditional style you know, doing even traditional style you know, doing even traditional style bodybuilding work can help to maintain bodybuilding work can help to maintain bodybuilding work can help to maintain um mobility and and stability. So, if um mobility and and stability. So, if um mobility and and stability. So, if people are just getting into resistance people are just getting into resistance people are just getting into resistance training for the first time, the safest training for the first time, the safest training for the first time, the safest and easiest and best way to do it is to and easiest and best way to do it is to and easiest and best way to do it is to train like a bodybuilder. Um, and that train like a bodybuilder. Um, and that train like a bodybuilder. Um, and that could be a combination of compound or could be a combination of compound or could be a combination of compound or machine or um, you know, dumbbell bands, machine or um, you know, dumbbell bands, machine or um, you know, dumbbell bands, anything like that, you're going to anything like that, you're going to anything like that, you're going to significantly improve strength. You're significantly improve strength. You're significantly improve strength. You're going to maintain muscle mass or improve going to maintain muscle mass or improve going to maintain muscle mass or improve muscle mass. You're going to improve muscle mass. You're going to improve muscle mass. You're going to improve types of muscle fibers. These are the types of muscle fibers. These are the types of muscle fibers. These are the ones we know are important for, you ones we know are important for, you ones we know are important for, you know, um, strength and power. um and the know, um, strength and power. um and the know, um, strength and power. um and the injury risk is super super low. Of injury risk is super super low. Of injury risk is super super low. Of course, you're then hopefully doing all course, you're then hopefully doing all course, you're then hopefully doing all these other things that we mentioned these other things that we mentioned these other things that we mentioned that require you to um you know have that require you to um you know have that require you to um you know have some element of um you know flexibility some element of um you know flexibility some element of um you know flexibility uh stability, cutting, jumping, running uh stability, cutting, jumping, running uh stability, cutting, jumping, running if you're doing some kind of bull sport if you're doing some kind of bull sport if you're doing some kind of bull sport or team sport, you're doing a martial or team sport, you're doing a martial or team sport, you're doing a martial art um because those things are art um because those things are art um because those things are important as well. But even you important as well. But even you important as well. But even you especially if if people are new to it, especially if if people are new to it, especially if if people are new to it, even bodybuilding style training is even bodybuilding style training is even bodybuilding style training is going to give you a number of a number going to give you a number of a number going to give you a number of a number of those benefits. So I don't I don't of those benefits. So I don't I don't of those benefits. So I don't I don't think that we want to avoid it entirely think that we want to avoid it entirely think that we want to avoid it entirely because the the evidence that we have because the the evidence that we have because the the evidence that we have from randomized control trials for like from randomized control trials for like from randomized control trials for like what type of resistance training what type of resistance training what type of resistance training significantly improves brain structure significantly improves brain structure significantly improves brain structure and function in older adults is that and function in older adults is that and function in older adults is that like super super basic bodybuilding like super super basic bodybuilding like super super basic bodybuilding style training. style training. style training. >> Interesting. >> Interesting. >> Interesting. >> This podcast is brought to you by >> This podcast is brought to you by >> This podcast is brought to you by Squarespace.

And honestly, I got to tell you that is how go brewing got to tell you that is how go brewing got to tell you that is how go brewing feels to me personally because a few feels to me personally because a few feels to me personally because a few years back I spoke at this event in years back I spoke at this event in years back I spoke at this event in Illinois. It was called Go. And it was Illinois. It was called Go. And it was Illinois. It was called Go. And it was all about taking inspired action in your all about taking inspired action in your all about taking inspired action in your life. And I had no idea that something life. And I had no idea that something life. And I had no idea that something from that day would land so deeply with from that day would land so deeply with from that day would land so deeply with Joe, the founder of the event, or that Joe, the founder of the event, or that Joe, the founder of the event, or that it would eventually become the spark for it would eventually become the spark for it would eventually become the spark for his next mission, which is reimagining his next mission, which is reimagining his next mission, which is reimagining what social drinking could look like. what social drinking could look like. what social drinking could look like. What impresses me the most is how What impresses me the most is how What impresses me the most is how seriously the entire team at Go takes seriously the entire team at Go takes seriously the entire team at Go takes their craft.

So how do you want to kind of mouths. So how do you want to kind of mouths. So how do you want to kind of introduce how you think about food? So I introduce how you think about food? So I introduce how you think about food? So I I think about food in in terms of sort I think about food in in terms of sort I think about food in in terms of sort of three three again kind of inter of three three again kind of inter of three three again kind of inter interacting um uh features of of a diet interacting um uh features of of a diet interacting um uh features of of a diet say and those are the nutrients, the say and those are the nutrients, the say and those are the nutrients, the energy and then the pattern of the way energy and then the pattern of the way energy and then the pattern of the way that you eat that allows you to maintain that you eat that allows you to maintain that you eat that allows you to maintain um good intake of the nutrients that you um good intake of the nutrients that you um good intake of the nutrients that you need as well as um adequate energy need as well as um adequate energy need as well as um adequate energy intake. um in intake. um in intake. um in the the the kind of the modernized westernized kind of the modernized westernized kind of the modernized westernized world. I think world. I think world. I think energy availability is probably the the energy availability is probably the the energy availability is probably the the right now seems to be the most important right now seems to be the most important right now seems to be the most important lever that we need to consider when it lever that we need to consider when it lever that we need to consider when it comes to to long-term brain health. comes to to long-term brain health. comes to to long-term brain health. Mainly because of all the things that we Mainly because of all the things that we Mainly because of all the things that we talked about earlier, right? We know talked about earlier, right? We know talked about earlier, right? We know that there's an increasing rate of that there's an increasing rate of that there's an increasing rate of pre-diabetes, metabolic syndrome. These pre-diabetes, metabolic syndrome. These pre-diabetes, metabolic syndrome. These come with high blood sugar, high blood come with high blood sugar, high blood come with high blood sugar, high blood pressure. These are significant risk pressure. These are significant risk pressure. These are significant risk factors for dementia. We know that factors for dementia. We know that factors for dementia. We know that people who have metabolic disease have people who have metabolic disease have people who have metabolic disease have an increased risk of multiple types of an increased risk of multiple types of an increased risk of multiple types of dementia. And this is something that dementia. And this is something that dementia. And this is something that really we're at risk at at a population really we're at risk at at a population really we're at risk at at a population level because of the of the food level because of the of the food level because of the of the food environment. You do see and this is environment. You do see and this is environment. You do see and this is relevant to to athletes and and relevant to to athletes and and relevant to to athletes and and longevity pe sort of focused people as longevity pe sort of focused people as longevity pe sort of focused people as well. you see this like bell-shaped well. you see this like bell-shaped well. you see this like bell-shaped curve between curve between curve between the amount of energy that we have in our the amount of energy that we have in our the amount of energy that we have in our bodies, amount of energy availability we bodies, amount of energy availability we bodies, amount of energy availability we have in our bodies um and the sort of have in our bodies um and the sort of have in our bodies um and the sort of the structure of our brains um something the structure of our brains um something the structure of our brains um something we call brain reserve which is we call brain reserve which is we call brain reserve which is essentially um a fancy way of saying how essentially um a fancy way of saying how essentially um a fancy way of saying how much brain do you have in your skull um much brain do you have in your skull um much brain do you have in your skull um and the more the better usually. So at and the more the better usually. So at and the more the better usually. So at the high end we know we have lower brain the high end we know we have lower brain the high end we know we have lower brain reserve, higher risk of long-term reserve, higher risk of long-term reserve, higher risk of long-term cognitive decline and dementia. We see cognitive decline and dementia. We see cognitive decline and dementia. We see that uh based on blood sugar or blood that uh based on blood sugar or blood that uh based on blood sugar or blood pressure um or um you know like central pressure um or um you know like central pressure um or um you know like central central adoposity like a high waist to central adoposity like a high waist to central adoposity like a high waist to hip or high waist to height ratio. But hip or high waist to height ratio. But hip or high waist to height ratio. But we also see the same thing at the low we also see the same thing at the low we also see the same thing at the low end and this has come from sort of big end and this has come from sort of big end and this has come from sort of big population studies across multiple population studies across multiple population studies across multiple populations around the world including populations around the world including populations around the world including some huntergatherer populations where some huntergatherer populations where some huntergatherer populations where they don't have access to the kinds of they don't have access to the kinds of they don't have access to the kinds of calories that that we do. Um, but this calories that that we do. Um, but this calories that that we do. Um, but this is very relevant to sort of like is very relevant to sort of like is very relevant to sort of like athletes and the longevity groups athletes and the longevity groups athletes and the longevity groups because you see that if you have low because you see that if you have low because you see that if you have low energy availability and you'll probably energy availability and you'll probably energy availability and you'll probably have maybe experienced this yourself or have maybe experienced this yourself or have maybe experienced this yourself or you've experienced it with other you've experienced it with other you've experienced it with other athletes you've worked with, we know athletes you've worked with, we know athletes you've worked with, we know that low energy availability or relative that low energy availability or relative that low energy availability or relative energy deficiency in sport uh reds or energy deficiency in sport uh reds or energy deficiency in sport uh reds or red s is associated with significant red s is associated with significant red s is associated with significant changes in cognitive function, mood, changes in cognitive function, mood, changes in cognitive function, mood, sleep and it's sort of like the sleep and it's sort of like the sleep and it's sort of like the population level those who have you know population level those who have you know population level those who have you know low energy availability have tend to low energy availability have tend to low energy availability have tend to have smaller brains because they just have smaller brains because they just have smaller brains because they just don't have the energy required to don't have the energy required to don't have the energy required to maintain that much structure of the maintain that much structure of the maintain that much structure of the brain. So this is relevant for those who brain. So this is relevant for those who brain. So this is relevant for those who are doing very high volumes of exercise, are doing very high volumes of exercise, are doing very high volumes of exercise, I think, but it's also relevant to those I think, but it's also relevant to those I think, but it's also relevant to those who think that chronic caloric who think that chronic caloric who think that chronic caloric restriction is like some font of of restriction is like some font of of restriction is like some font of of longevity. And I I think that we have longevity. And I I think that we have longevity. And I I think that we have evidence to say that's probably not the evidence to say that's probably not the evidence to say that's probably not the case. um you need to get enough energy case. um you need to get enough energy case. um you need to get enough energy in that you you remain um weight stable in that you you remain um weight stable in that you you remain um weight stable whilst maintaining strength and you know whilst maintaining strength and you know whilst maintaining strength and you know strength, performance, fitness, all strength, performance, fitness, all strength, performance, fitness, all these other things that we know require these other things that we know require these other things that we know require some amount of energy. Um so like some amount of energy. Um so like some amount of energy. Um so like chronic restriction is is potentially chronic restriction is is potentially chronic restriction is is potentially going to be uh bad there as in addition going to be uh bad there as in addition going to be uh bad there as in addition to chronic excess. If we're sort of like to chronic excess. If we're sort of like to chronic excess. If we're sort of like attending to our energy needs, then the attending to our energy needs, then the attending to our energy needs, then the next important thing or you know which next important thing or you know which next important thing or you know which we know is equally important at least we know is equally important at least we know is equally important at least sort of on a g global scale is is sort of on a g global scale is is sort of on a g global scale is is nutrients that are essential for brain nutrients that are essential for brain nutrients that are essential for brain function. So these are all the things I function. So these are all the things I function. So these are all the things I mentioned earlier are the ones that we mentioned earlier are the ones that we mentioned earlier are the ones that we have the best evidence for. So um iron have the best evidence for. So um iron have the best evidence for. So um iron status, vitamin D status, omega-3, the B status, vitamin D status, omega-3, the B status, vitamin D status, omega-3, the B vitamins associated with um methylation. vitamins associated with um methylation. vitamins associated with um methylation. So the ones that affect our homocyine So the ones that affect our homocyine So the ones that affect our homocyine level and homocyine goes up as our need level and homocyine goes up as our need level and homocyine goes up as our need for these um B vitamins goes up. So if for these um B vitamins goes up. So if for these um B vitamins goes up. So if we have inadequate levels, homocyine we have inadequate levels, homocyine we have inadequate levels, homocyine tends to go up and so that's B12, tends to go up and so that's B12, tends to go up and so that's B12, folate, uh B6 and rioflavin, which is folate, uh B6 and rioflavin, which is folate, uh B6 and rioflavin, which is B2. Um and then on top of that, you B2. Um and then on top of that, you B2. Um and then on top of that, you know, we we know there's important know, we we know there's important know, we we know there's important things related to antioxidant things related to antioxidant things related to antioxidant polyphenols. So the things that make polyphenols. So the things that make polyphenols. So the things that make berries um purple like the anthocyanins berries um purple like the anthocyanins berries um purple like the anthocyanins or we see similar compounds in coffee or we see similar compounds in coffee or we see similar compounds in coffee and tea um which are associated with a and tea um which are associated with a and tea um which are associated with a lower risk of dementia at sort of lower risk of dementia at sort of lower risk of dementia at sort of moderate consumption. Chocolate uh the moderate consumption. Chocolate uh the moderate consumption. Chocolate uh the roasted uh skins of nuts and seeds have roasted uh skins of nuts and seeds have roasted uh skins of nuts and seeds have like similar compounds in them. Then like similar compounds in them. Then like similar compounds in them. Then there's things like luteine and there's things like luteine and there's things like luteine and zeazanthin that make your peppers and zeazanthin that make your peppers and zeazanthin that make your peppers and carrots or make your peppers red and carrots or make your peppers red and carrots or make your peppers red and yellow. Um the the carotenoids including yellow. Um the the carotenoids including yellow. Um the the carotenoids including like betaarotene in in carrots. Um and like betaarotene in in carrots. Um and like betaarotene in in carrots. Um and then things like aazanthin which makes then things like aazanthin which makes then things like aazanthin which makes salmon and shrimp pink. Um all of these salmon and shrimp pink. Um all of these salmon and shrimp pink. Um all of these have sort of like similar benefits. Um have sort of like similar benefits. Um have sort of like similar benefits. Um or and in terms of they they affect gut or and in terms of they they affect gut or and in terms of they they affect gut function, affect vascular function and function, affect vascular function and function, affect vascular function and they can um uh improve brain function. they can um uh improve brain function. they can um uh improve brain function. Some of the best evidence is for uh Some of the best evidence is for uh Some of the best evidence is for uh blueberries or like dark berries. Dozens blueberries or like dark berries. Dozens blueberries or like dark berries. Dozens of studies showing both uh acute and of studies showing both uh acute and of studies showing both uh acute and chronic benefits in terms of cognitive chronic benefits in terms of cognitive chronic benefits in terms of cognitive function with with berry with berry function with with berry with berry function with with berry with berry intake. And then uh yeah, some of the intake. And then uh yeah, some of the intake. And then uh yeah, some of the antioxidants things like vitamin C, antioxidants things like vitamin C, antioxidants things like vitamin C, vitamin E, um uh uh magnesium and zinc vitamin E, um uh uh magnesium and zinc vitamin E, um uh uh magnesium and zinc crop up frequently as well. All of this crop up frequently as well. All of this crop up frequently as well. All of this to say that I call nutrients the great to say that I call nutrients the great to say that I call nutrients the great leveler. Like these nutrients are leveler. Like these nutrients are leveler. Like these nutrients are important. I want you to have enough of important. I want you to have enough of important. I want you to have enough of them. I don't mind where you get them them. I don't mind where you get them them. I don't mind where you get them from and I don't think I think that from and I don't think I think that from and I don't think I think that matters much less. To your point of not matters much less. To your point of not matters much less. To your point of not caring where you get them from, caring where you get them from, caring where you get them from, >> do you care if they come from the whole >> do you care if they come from the whole >> do you care if they come from the whole food versus supplementation? food versus supplementation? food versus supplementation? >> I would prefer if they came from the >> I would prefer if they came from the >> I would prefer if they came from the whole food. Um, and I think the the best whole food. Um, and I think the the best whole food. Um, and I think the the best uh example of that is is seafood. So uh example of that is is seafood. So uh example of that is is seafood. So when we look at omega-3 status and when we look at omega-3 status and when we look at omega-3 status and dementia risk in general, it seems that dementia risk in general, it seems that dementia risk in general, it seems that sort of like the pop, you if you're sort of like the pop, you if you're sort of like the pop, you if you're doing epidemiological studies, those doing epidemiological studies, those doing epidemiological studies, those who, you know, regularly consume seafood who, you know, regularly consume seafood who, you know, regularly consume seafood have a a greater reduction in their have a a greater reduction in their have a a greater reduction in their dementia risk than those who take dementia risk than those who take dementia risk than those who take omega-3 supplements. That's probably omega-3 supplements. That's probably omega-3 supplements. That's probably because there's a whole bunch of other because there's a whole bunch of other because there's a whole bunch of other stuff in there that's important, right? stuff in there that's important, right? stuff in there that's important, right? So uh selenium um you maybe as you if So uh selenium um you maybe as you if So uh selenium um you maybe as you if you're eating salmon or shrimp you're you're eating salmon or shrimp you're you're eating salmon or shrimp you're getting asanthin as a as a as an getting asanthin as a as a as an getting asanthin as a as a as an antioxidant and in general the the our antioxidant and in general the the our antioxidant and in general the the our diets are relatively poor in in in many diets are relatively poor in in in many diets are relatively poor in in in many of these antioxidants I mentioned. Um of these antioxidants I mentioned. Um of these antioxidants I mentioned. Um you know protein if you if you need to you know protein if you if you need to you know protein if you if you need to if you're not getting enough protein in if you're not getting enough protein in if you're not getting enough protein in your diet. So and there's a whole bunch your diet. So and there's a whole bunch your diet. So and there's a whole bunch of other stuff. So there's this nice um of other stuff. So there's this nice um of other stuff. So there's this nice um uh phrase which is nutritional dark uh phrase which is nutritional dark uh phrase which is nutritional dark matter where it basically acknowledges matter where it basically acknowledges matter where it basically acknowledges that like 90% of what's in your whole that like 90% of what's in your whole that like 90% of what's in your whole foods we have we don't know what it is foods we have we don't know what it is foods we have we don't know what it is and we don't know what it does. Um and we don't know what it does. Um and we don't know what it does. Um there's uh interesting compounds like there's uh interesting compounds like there's uh interesting compounds like ergoionine that you get from mushrooms ergoionine that you get from mushrooms ergoionine that you get from mushrooms that's like the new longevity supplement that's like the new longevity supplement that's like the new longevity supplement because it does a bunch of cool things. because it does a bunch of cool things. because it does a bunch of cool things. Um but we're only just learning about Um but we're only just learning about Um but we're only just learning about them. So when you get it from the whole them. So when you get it from the whole them. So when you get it from the whole food you're kind of stacking the deck in food you're kind of stacking the deck in food you're kind of stacking the deck in terms of there's some other stuff in terms of there's some other stuff in terms of there's some other stuff in here that may be beneficial too. here that may be beneficial too. here that may be beneficial too. However, there are studies where if you However, there are studies where if you However, there are studies where if you supplement with omega-3s and you're supplement with omega-3s and you're supplement with omega-3s and you're omega-3 deficient, you see significant omega-3 deficient, you see significant omega-3 deficient, you see significant improvements in cognitive function and improvements in cognitive function and improvements in cognitive function and the rate of cognitive decline. Um, the the rate of cognitive decline. Um, the the rate of cognitive decline. Um, the omega-3s in particular interact with B omega-3s in particular interact with B omega-3s in particular interact with B vitamin status. So, there are multiple vitamin status. So, there are multiple vitamin status. So, there are multiple studies that show that if you supplement studies that show that if you supplement studies that show that if you supplement with omega-3s, but you have poor B with omega-3s, but you have poor B with omega-3s, but you have poor B vitamin status, then you don't benefit vitamin status, then you don't benefit vitamin status, then you don't benefit from the omega-3s. And vice versa, if from the omega-3s. And vice versa, if from the omega-3s. And vice versa, if you supplement with B vitamins, but you you supplement with B vitamins, but you you supplement with B vitamins, but you have poor omega-3 status, you don't you have poor omega-3 status, you don't you have poor omega-3 status, you don't you don't benefit from the B vitamins. And I don't benefit from the B vitamins. And I don't benefit from the B vitamins. And I think this is where reductionism has think this is where reductionism has think this is where reductionism has gotten us in trouble in supplementation gotten us in trouble in supplementation gotten us in trouble in supplementation um studies, which is that we we give um studies, which is that we we give um studies, which is that we we give thousands of people one supplement. thousands of people one supplement. thousands of people one supplement. We're like, "Oh, hey, it doesn't reduce We're like, "Oh, hey, it doesn't reduce We're like, "Oh, hey, it doesn't reduce dementia risk. Therefore, it doesn't dementia risk. Therefore, it doesn't dementia risk. Therefore, it doesn't work." Well, you didn't measure whether work." Well, you didn't measure whether work." Well, you didn't measure whether they needed it, and you didn't measure they needed it, and you didn't measure they needed it, and you didn't measure the other things that that um that the other things that that um that the other things that that um that supplement is dependent on. So, one of supplement is dependent on. So, one of supplement is dependent on. So, one of the reasons why I think it's safer to the reasons why I think it's safer to the reasons why I think it's safer to get things from whole foods is because get things from whole foods is because get things from whole foods is because you're getting these other nutrients at you're getting these other nutrients at you're getting these other nutrients at the same time. But with that said, if the same time. But with that said, if the same time. But with that said, if you're somebody who doesn't consume you're somebody who doesn't consume you're somebody who doesn't consume seafood or, you know, any other source seafood or, you know, any other source seafood or, you know, any other source of longchain omega-3s, I know that of longchain omega-3s, I know that of longchain omega-3s, I know that there's benefit from you supplementing there's benefit from you supplementing there's benefit from you supplementing uh from it. So, that's kind of the the uh from it. So, that's kind of the the uh from it. So, that's kind of the the approach that I I would use. approach that I I would use. approach that I I would use. >> Yeah. Yeah. Yeah. Yeah. That makes >> Yeah. Yeah. Yeah. Yeah. That makes >> Yeah. Yeah. Yeah. Yeah. That makes sense. I'm going to have more questions sense. I'm going to have more questions sense. I'm going to have more questions about these pillars, but let's get about these pillars, but let's get about these pillars, but let's get through them. So, we talked about through them. So, we talked about through them. So, we talked about energy, we talked about nutrients, um energy, we talked about nutrients, um energy, we talked about nutrients, um and then the other pillar here is and then the other pillar here is and then the other pillar here is pattern. pattern. pattern. >> Yeah. passen is just finding a way that >> Yeah. passen is just finding a way that >> Yeah. passen is just finding a way that you can achieve um adequate energy you can achieve um adequate energy you can achieve um adequate energy intake and good nutrient intake in a intake and good nutrient intake in a intake and good nutrient intake in a sustainable way for you, right? That's sustainable way for you, right? That's sustainable way for you, right? That's either um what you can afford, what you either um what you can afford, what you either um what you can afford, what you have access to, what's um makes sense have access to, what's um makes sense have access to, what's um makes sense for you uh culturally or locally um uh for you uh culturally or locally um uh for you uh culturally or locally um uh financially. And I think that there are financially. And I think that there are financially. And I think that there are innumerable ways to to skin those cats. innumerable ways to to skin those cats. innumerable ways to to skin those cats. It's just making sure that you're kind It's just making sure that you're kind It's just making sure that you're kind of hitting those targets in a way that's of hitting those targets in a way that's of hitting those targets in a way that's sustainable for you. So that's why like sustainable for you. So that's why like sustainable for you. So that's why like pattern is that last part because right pattern is that last part because right pattern is that last part because right when we take a supplement we usually when we take a supplement we usually when we take a supplement we usually take it for a month and then we forget take it for a month and then we forget take it for a month and then we forget to reby it. We never take we never take to reby it. We never take we never take to reby it. We never take we never take it again. But this is something that's it again. But this is something that's it again. But this is something that's going to be important long term. So going to be important long term. So going to be important long term. So finding a way to make this sustainable, finding a way to make this sustainable, finding a way to make this sustainable, enjoyable, nourishing um like that's enjoyable, nourishing um like that's enjoyable, nourishing um like that's where pattern you know really becomes where pattern you know really becomes where pattern you know really becomes important. setting aside this diet important. setting aside this diet important. setting aside this diet versus that diet and returning now to versus that diet and returning now to versus that diet and returning now to this notion of energy. You mentioned this notion of energy. You mentioned this notion of energy. You mentioned that there is a certain cohort cohort of that there is a certain cohort cohort of that there is a certain cohort cohort of people in the longevity community who people in the longevity community who people in the longevity community who you know are are under the impression you know are are under the impression you know are are under the impression that like chronic uh under fueling is that like chronic uh under fueling is that like chronic uh under fueling is some secret to unlocking health span some secret to unlocking health span some secret to unlocking health span extension. But the vast majority of extension. But the vast majority of extension. But the vast majority of people are overindulging. You know, people are overindulging. You know, people are overindulging. You know, we're in this world of over we're in this world of over we're in this world of over overabundance. Everybody's eating too overabundance. Everybody's eating too overabundance. Everybody's eating too much. Everybody, you know, is a little much. Everybody, you know, is a little much. Everybody, you know, is a little overweight, if not a lot overweight. So, overweight, if not a lot overweight. So, overweight, if not a lot overweight. So, >> we can sort of set aside, you know, >> we can sort of set aside, you know, >> we can sort of set aside, you know, those longevity people and focus on the those longevity people and focus on the those longevity people and focus on the average person. average person. average person. >> Uh, and one of the things that I thought >> Uh, and one of the things that I thought >> Uh, and one of the things that I thought was really interesting that you said, was really interesting that you said, was really interesting that you said, which is overeating shrinks the brain. which is overeating shrinks the brain. which is overeating shrinks the brain. >> Yeah. >> Yeah. >> Yeah. >> So, explain that >> So, explain that >> So, explain that because we're all overeating. because we're all overeating. because we're all overeating. >> Yeah. There's definitely um like a step >> Yeah. There's definitely um like a step >> Yeah. There's definitely um like a step a step in between. Um, but we know that a step in between. Um, but we know that a step in between. Um, but we know that even in short-term overfeeding studies, even in short-term overfeeding studies, even in short-term overfeeding studies, right, and this is usually done with right, and this is usually done with right, and this is usually done with some version of a western diet, they add some version of a western diet, they add some version of a western diet, they add candy bars to the diet or they make you candy bars to the diet or they make you candy bars to the diet or they make you eat an extra like serving of French eat an extra like serving of French eat an extra like serving of French toast or waffles every day for for like toast or waffles every day for for like toast or waffles every day for for like even a week. You can start to see even a week. You can start to see even a week. You can start to see changes in um both mood and say h like changes in um both mood and say h like changes in um both mood and say h like hypocample function, memory function. hypocample function, memory function. hypocample function, memory function. This is in this is in in humans. this This is in this is in in humans. this This is in this is in in humans. this then you know long-term translates into then you know long-term translates into then you know long-term translates into what we see in the large population what we see in the large population what we see in the large population studies which is people who have um studies which is people who have um studies which is people who have um higher markers of what I call excess higher markers of what I call excess higher markers of what I call excess energy availability um and so that's energy availability um and so that's energy availability um and so that's essentially the markers of metabolic essentially the markers of metabolic essentially the markers of metabolic syndrome um those are the ones we have syndrome um those are the ones we have syndrome um those are the ones we have the best evidence for so a high waist the best evidence for so a high waist the best evidence for so a high waist circumference low HDL cholesterol high circumference low HDL cholesterol high circumference low HDL cholesterol high triglycerides high blood sugar or high triglycerides high blood sugar or high triglycerides high blood sugar or high blood pressure these are all significant blood pressure these are all significant blood pressure these are all significant risk factors um for dementia and they risk factors um for dementia and they risk factors um for dementia and they are direct direct measurable effects of are direct direct measurable effects of are direct direct measurable effects of chronic excess calorie consumption. They chronic excess calorie consumption. They chronic excess calorie consumption. They are like the the outputs of excess are like the the outputs of excess are like the the outputs of excess energy. energy. energy. >> This this is what hundreds of millions >> This this is what hundreds of millions >> This this is what hundreds of millions of people are you know if they had their of people are you know if they had their of people are you know if they had their blood work done it would reflect those blood work done it would reflect those blood work done it would reflect those very things. very things. very things. >> Yes the depending on which estimate and >> Yes the depending on which estimate and >> Yes the depending on which estimate and which data set you have something like which data set you have something like which data set you have something like 10% of US adults don't have any of any 10% of US adults don't have any of any 10% of US adults don't have any of any of the um uh components of metabolic of the um uh components of metabolic of the um uh components of metabolic syndrome. you need um uh three to five syndrome. you need um uh three to five syndrome. you need um uh three to five to to technically have metabolic to to technically have metabolic to to technically have metabolic syndrome, but probably less than 10% syndrome, but probably less than 10% syndrome, but probably less than 10% don't have any of them. don't have any of them. don't have any of them. >> High blood pressure, elevated LDL, >> High blood pressure, elevated LDL, >> High blood pressure, elevated LDL, >> elevated triglycerides, LDL actually >> elevated triglycerides, LDL actually >> elevated triglycerides, LDL actually isn't in the LDL is one of the isn't in the LDL is one of the isn't in the LDL is one of the modifiable risk factors in the dementia modifiable risk factors in the dementia modifiable risk factors in the dementia prevention reports about so LDL and and prevention reports about so LDL and and prevention reports about so LDL and and cholesterol APOB are important, but cholesterol APOB are important, but cholesterol APOB are important, but they're not in the metabolic syndrome they're not in the metabolic syndrome they're not in the metabolic syndrome criteria. criteria. criteria. >> Okay. So given the fact that we're >> Okay. So given the fact that we're >> Okay. So given the fact that we're overindulging on food and a lot of these overindulging on food and a lot of these overindulging on food and a lot of these foods are we're not overindulging on foods are we're not overindulging on foods are we're not overindulging on whole foods, we're overindulging on whole foods, we're overindulging on whole foods, we're overindulging on ultrarocessed foods and just you know a ultrarocessed foods and just you know a ultrarocessed foods and just you know a bunch of crap. And bunch of crap. And bunch of crap. And >> I know just as somebody who's always >> I know just as somebody who's always >> I know just as somebody who's always trying to make the right choice when I'm trying to make the right choice when I'm trying to make the right choice when I'm not at home where I have control over my not at home where I have control over my not at home where I have control over my food, I'm traveling or you know I'm at a food, I'm traveling or you know I'm at a food, I'm traveling or you know I'm at a restaurant or whatever. Like it's very restaurant or whatever. Like it's very restaurant or whatever. Like it's very difficult to really eat well because difficult to really eat well because difficult to really eat well because even if you order the salad, there's too even if you order the salad, there's too even if you order the salad, there's too much dressing on it or they load it with much dressing on it or they load it with much dressing on it or they load it with all kinds of other stuff to because they all kinds of other stuff to because they all kinds of other stuff to because they think that's what people want in order think that's what people want in order think that's what people want in order for it to taste good. Like even the for it to taste good. Like even the for it to taste good. Like even the healthy choice is compromised. So you're healthy choice is compromised. So you're healthy choice is compromised. So you're really going against the grain to try really going against the grain to try really going against the grain to try to, you know, do the right thing unless to, you know, do the right thing unless to, you know, do the right thing unless you're in your, you know, kind of you're in your, you know, kind of you're in your, you know, kind of personal controlled environment. I personal controlled environment. I personal controlled environment. I >> I think that's absolutely right. And >> I think that's absolutely right. And >> I think that's absolutely right. And the the way that I would think about the the way that I would think about the the way that I would think about this and and think about you know this and and think about you know this and and think about you know everything that we have talked about and everything that we have talked about and everything that we have talked about and will talk about today is that as much as will talk about today is that as much as will talk about today is that as much as possible you know control this possible you know control this possible you know control this environment at home right. So if you um environment at home right. So if you um environment at home right. So if you um you know, however it is that you eat at you know, however it is that you eat at you know, however it is that you eat at home or that you would you would like to home or that you would you would like to home or that you would you would like to eat um figuring out how you can um eat um figuring out how you can um eat um figuring out how you can um access those foods, cook them, you make access those foods, cook them, you make access those foods, cook them, you make them a part of your your diet in a them a part of your your diet in a them a part of your your diet in a sustainable, enjoyable way, right? Or sustainable, enjoyable way, right? Or sustainable, enjoyable way, right? Or and it's the same with exercise, right? and it's the same with exercise, right? and it's the same with exercise, right? You have your routine, you play your You have your routine, you play your You have your routine, you play your pickle ball, you you go and you lift pickle ball, you you go and you lift pickle ball, you you go and you lift your weights. your weights. your weights. um so that when you do go out into the um so that when you do go out into the um so that when you do go out into the world and these choices are harder, it world and these choices are harder, it world and these choices are harder, it matters much less because this stuff matters much less because this stuff matters much less because this stuff integrates over really long periods of integrates over really long periods of integrates over really long periods of time, right? So one meal out doesn't time, right? So one meal out doesn't time, right? So one meal out doesn't make that much of a difference. And we make that much of a difference. And we make that much of a difference. And we get to the point where like I have get to the point where like I have get to the point where like I have friends where you and you know friends where you and you know friends where you and you know historically you go you you know when historically you go you you know when historically you go you you know when you're in this health kind of world you you're in this health kind of world you you're in this health kind of world you know everybody goes out to dinner after know everybody goes out to dinner after know everybody goes out to dinner after a conference and right everybody's a conference and right everybody's a conference and right everybody's stressed about what they can or should stressed about what they can or should stressed about what they can or should order at the restaurant right and I order at the restaurant right and I order at the restaurant right and I think we want to avoid that because it's think we want to avoid that because it's think we want to avoid that because it's a net negative right just like in in a net negative right just like in in a net negative right just like in in enjoy the moment with the people and enjoy the moment with the people and enjoy the moment with the people and like what you eat that one time makes like what you eat that one time makes like what you eat that one time makes much less. This is the flip side of, you much less. This is the flip side of, you much less. This is the flip side of, you know, these kinds of conversations know, these kinds of conversations know, these kinds of conversations because we're basically, you know, because we're basically, you know, because we're basically, you know, pushing people towards this optimization pushing people towards this optimization pushing people towards this optimization mindset mindset mindset >> where it's impossible to live up to the >> where it's impossible to live up to the >> where it's impossible to live up to the standards that are being articulated and standards that are being articulated and standards that are being articulated and that leads to guilt and shame and stress that leads to guilt and shame and stress that leads to guilt and shame and stress and all these other things that are and all these other things that are and all these other things that are obviously, you know, cross purposes with obviously, you know, cross purposes with obviously, you know, cross purposes with the aim. the aim. the aim. >> Yeah. No. And I I think that, you know, >> Yeah. No. And I I think that, you know, >> Yeah. No. And I I think that, you know, a lot of what I write about in the book a lot of what I write about in the book a lot of what I write about in the book is the psychology of how we approach is the psychology of how we approach is the psychology of how we approach this kind of health information because this kind of health information because this kind of health information because that's exactly what I want to avoid. I that's exactly what I want to avoid. I that's exactly what I want to avoid. I don't want people to feel like they're don't want people to feel like they're don't want people to feel like they're not doing enough. Um I mean, and we know not doing enough.

We know that you need to find a way to We know that you need to find a way to We know that you need to find a way to kind of have this sustainable but kind of have this sustainable but kind of have this sustainable but nourishing diet that gives you the nourishing diet that gives you the nourishing diet that gives you the nutrients and that you're not nutrients and that you're not nutrients and that you're not overeating. And we know that you need overeating. And we know that you need overeating. And we know that you need to, you know, create some kind of to, you know, create some kind of to, you know, create some kind of cognitive stimulus so you need to lean cognitive stimulus so you need to lean cognitive stimulus so you need to lean into the discomfort, right? We know that into the discomfort, right? We know that into the discomfort, right? We know that you have to do those things, but if you you have to do those things, but if you you have to do those things, but if you get to the point where you're constantly get to the point where you're constantly get to the point where you're constantly feeling like you're not doing enough, feeling like you're not doing enough, feeling like you're not doing enough, you're not doing well enough, you need you're not doing well enough, you need you're not doing well enough, you need to do more, that's an inherent stress in to do more, that's an inherent stress in to do more, that's an inherent stress in its own way that that then negatively its own way that that then negatively its own way that that then negatively impacts your health.

Um, I would focus on need tons of pasta. Um, I would focus on the things that sort of those other the things that sort of those other the things that sort of those other because they're not particular they're because they're not particular they're because they're not particular they're both calorie dense um and relatively both calorie dense um and relatively both calorie dense um and relatively nutrient poor. nutrient poor. nutrient poor. >> Um, so focusing on those other areas um >> Um, so focusing on those other areas um >> Um, so focusing on those other areas um I think is going to give is going to I think is going to give is going to I think is going to give is going to make you more satiated as well as giving make you more satiated as well as giving make you more satiated as well as giving you sort of more sort of nutrient bang you sort of more sort of nutrient bang you sort of more sort of nutrient bang for your buck.

So, those those are those are the >> Yeah. So, those those are those are the >> Yeah. So, those those are those are the two that that I' and and you can just two that that I' and and you can just two that that I' and and you can just you can just measure, right? So, measure you can just measure, right? So, measure you can just measure, right? So, measure your homoyine level. The goal is to be your homoyine level. The goal is to be your homoyine level. The goal is to be at least below 13, ideally below 10. uh at least below 13, ideally below 10. uh at least below 13, ideally below 10. uh you can measure your omega-3 status. So you can measure your omega-3 status. So you can measure your omega-3 status. So omega three index at least above six, omega three index at least above six, omega three index at least above six, ideally above eight. The other thing ideally above eight. The other thing ideally above eight. The other thing where it's just it's common particularly where it's just it's common particularly where it's just it's common particularly as as people get older to not consume as as people get older to not consume as as people get older to not consume enough of is just making sure you get enough of is just making sure you get enough of is just making sure you get enough high quality protein. Um enough high quality protein. Um enough high quality protein. Um especially as people get older, they get especially as people get older, they get especially as people get older, they get more frail or they experience a more frail or they experience a more frail or they experience a metabolic disease that's associated with metabolic disease that's associated with metabolic disease that's associated with a faster loss of like muscle mass and a faster loss of like muscle mass and a faster loss of like muscle mass and strength. Um, and there are randomized strength. Um, and there are randomized strength. Um, and there are randomized control trials that showing that that control trials that showing that that control trials that showing that that show that increasing the amount of show that increasing the amount of show that increasing the amount of protein you eat to sort of actually what protein you eat to sort of actually what protein you eat to sort of actually what is now the target level in the the is now the target level in the the is now the target level in the the updated dietary guidelines that's updated dietary guidelines that's updated dietary guidelines that's actually in the in the trials is actually in the in the trials is actually in the in the trials is associated with better maintenance of associated with better maintenance of associated with better maintenance of muscle mass in in sort of older in older muscle mass in in sort of older in older muscle mass in in sort of older in older adults. So that's the only other thing adults. So that's the only other thing adults. So that's the only other thing that I would those Yeah. So B vitamins, that I would those Yeah. So B vitamins, that I would those Yeah. So B vitamins, omega-3s, protein are the ones that are omega-3s, protein are the ones that are omega-3s, protein are the ones that are maybe easiest to to to miss out on. maybe easiest to to to miss out on. maybe easiest to to to miss out on. >> The protein recommendations just seem to >> The protein recommendations just seem to >> The protein recommendations just seem to continue to go up. I can't I've never continue to go up. I can't I've never continue to go up. I can't I've never been eating protein at that threshold been eating protein at that threshold been eating protein at that threshold level. I think I've always been eating level. I think I've always been eating level. I think I've always been eating less protein. I still I I really don't less protein. I still I I really don't less protein. I still I I really don't have trouble putting on muscle mass. have trouble putting on muscle mass. have trouble putting on muscle mass. It's like I've now recovered enough from It's like I've now recovered enough from It's like I've now recovered enough from a spinal fusion surgery I had this past a spinal fusion surgery I had this past a spinal fusion surgery I had this past spring where I'm in the gym and I'm spring where I'm in the gym and I'm spring where I'm in the gym and I'm noticing gains pretty regularly and I'm noticing gains pretty regularly and I'm noticing gains pretty regularly and I'm not really that focused on protein not really that focused on protein not really that focused on protein despite hearing from people like you all despite hearing from people like you all despite hearing from people like you all the time who are like you need to be you the time who are like you need to be you the time who are like you need to be you know one gram per body weight like I'm know one gram per body weight like I'm know one gram per body weight like I'm way below that but then I'm way below that but then I'm way below that but then I'm >> I'm like is it is it does it m I mean >> I'm like is it is it does it m I mean >> I'm like is it is it does it m I mean I'm hearing this obviously there's I'm hearing this obviously there's I'm hearing this obviously there's evidence to support that I should be evidence to support that I should be evidence to support that I should be thinking about this differently, but I thinking about this differently, but I thinking about this differently, but I haven't been. So, haven't been. So, haven't been. So, >> there's well, there's a few there's a >> there's well, there's a few there's a >> there's well, there's a few there's a few different parts that get that that few different parts that get that that few different parts that get that that go into that. So, the the first is that go into that. So, the the first is that go into that. So, the the first is that in the context of a calorie dense in the context of a calorie dense in the context of a calorie dense nutrient poor diet, we know that protein nutrient poor diet, we know that protein nutrient poor diet, we know that protein is a lever for society. So, um people is a lever for society. So, um people is a lever for society. So, um people will continue you, this is some of Kevin will continue you, this is some of Kevin will continue you, this is some of Kevin Hall's work, right? People will continue Hall's work, right? People will continue Hall's work, right? People will continue to eat until they they some of it will to eat until they they some of it will to eat until they they some of it will be some some protein threshold. So, one be some some protein threshold. So, one be some some protein threshold. So, one reason to focus on protein is that it's reason to focus on protein is that it's reason to focus on protein is that it's maybe going to help you overeat less, maybe going to help you overeat less, maybe going to help you overeat less, right? that's less of that's not that's right? that's less of that's not that's right? that's less of that's not that's not an issue for you, but a population not an issue for you, but a population not an issue for you, but a population level that can be important. level that can be important. level that can be important. >> Um, it's also particularly important as >> Um, it's also particularly important as >> Um, it's also particularly important as people start to age and experience people start to age and experience people start to age and experience frailty or psychopenia, right? That's frailty or psychopenia, right? That's frailty or psychopenia, right? That's the context I was talking about earlier. the context I was talking about earlier. the context I was talking about earlier. Again, that's not as relevant to you. Again, that's not as relevant to you. Again, that's not as relevant to you. >> But I'm at that age where it is harder, >> But I'm at that age where it is harder, >> But I'm at that age where it is harder, you know, and you're just like, well, you know, and you're just like, well, you know, and you're just like, well, this is taking a little bit longer, you this is taking a little bit longer, you this is taking a little bit longer, you know, like, so maybe I should be, you know, like, so maybe I should be, you know, like, so maybe I should be, you know, focused on on my protein. You do know, focused on on my protein. You do know, focused on on my protein. You do see that in old adults and now people in see that in old adults and now people in see that in old adults and now people in their 60s if they consume again at that their 60s if they consume again at that their 60s if they consume again at that sort of level of protein. So like 50 to sort of level of protein. So like 50 to sort of level of protein. So like 50 to 100% above what was like the previous 100% above what was like the previous 100% above what was like the previous dietary guidelines. So that was8 grams dietary guidelines. So that was8 grams dietary guidelines. So that was8 grams per kilo of body weight. Now we kind of per kilo of body weight. Now we kind of per kilo of body weight. Now we kind of think targeting 1.2 to 1.6 g per kilo of think targeting 1.2 to 1.6 g per kilo of think targeting 1.2 to 1.6 g per kilo of body weight. At that level you also have body weight. At that level you also have body weight. At that level you also have higher like antioxidant status which we higher like antioxidant status which we higher like antioxidant status which we know is important in terms of dementia know is important in terms of dementia know is important in terms of dementia risk factors is important for recovering risk factors is important for recovering risk factors is important for recovering from exercise as well. And then you're from exercise as well. And then you're from exercise as well. And then you're right, as you get older, like even if right, as you get older, like even if right, as you get older, like even if you're doing everything right, you're you're doing everything right, you're you're doing everything right, you're more likely to experience um anabolic more likely to experience um anabolic more likely to experience um anabolic resistance where you just need a greater resistance where you just need a greater resistance where you just need a greater protein signal or more of a training protein signal or more of a training protein signal or more of a training signal to kind of, you know, benefit signal to kind of, you know, benefit signal to kind of, you know, benefit from that exercise. So, it's probably from that exercise. So, it's probably from that exercise. So, it's probably worth you considering increasing um worth you considering increasing um worth you considering increasing um intake up to somewhere in that kind of intake up to somewhere in that kind of intake up to somewhere in that kind of range. Um the but the final thing I was range. Um the but the final thing I was range. Um the but the final thing I was going to say is that when it comes to going to say is that when it comes to going to say is that when it comes to muscle mass and strength, the most muscle mass and strength, the most muscle mass and strength, the most important thing is still stimulus, important thing is still stimulus, important thing is still stimulus, right? So, um, yes, eating more protein right? So, um, yes, eating more protein right? So, um, yes, eating more protein will prevent you losing muscle mass. If will prevent you losing muscle mass. If will prevent you losing muscle mass. If you're not, um, if you're not regularly you're not, um, if you're not regularly you're not, um, if you're not regularly doing some kind of resistance training, doing some kind of resistance training, doing some kind of resistance training, but resistance training is still going but resistance training is still going but resistance training is still going to be the most important thing. But, you to be the most important thing. But, you to be the most important thing. But, you know, as you get older, I think that know, as you get older, I think that know, as you get older, I think that requirements are going to are going to requirements are going to are going to requirements are going to are going to increase a bit. On the topic of increase a bit. On the topic of increase a bit. On the topic of omega-3s, omega-3s, omega-3s, uh I've had I I couldn't even count how uh I've had I I couldn't even count how uh I've had I I couldn't even count how many conversations with people like many conversations with people like many conversations with people like yourself sitting across the table, uh yourself sitting across the table, uh yourself sitting across the table, uh you know, discussing the finer points of you know, discussing the finer points of you know, discussing the finer points of of you know, how to supplement properly. of you know, how to supplement properly. of you know, how to supplement properly. And to this day, I will admit that I And to this day, I will admit that I And to this day, I will admit that I still don't quite under like there's still don't quite under like there's still don't quite under like there's DHEA and there's DHA and there's EPA and DHEA and there's DHA and there's EPA and DHEA and there's DHA and there's EPA and like I still don't understand like when like I still don't understand like when like I still don't understand like when I'm looking at a supplement like what I'm looking at a supplement like what I'm looking at a supplement like what are the levels I'm supposed to be um are the levels I'm supposed to be um are the levels I'm supposed to be um looking for? How do these things looking for? How do these things looking for? How do these things interact? And as a plant-based person, interact? And as a plant-based person, interact? And as a plant-based person, what maybe should I be thinking about what maybe should I be thinking about what maybe should I be thinking about that an omnivore isn't in terms of the that an omnivore isn't in terms of the that an omnivore isn't in terms of the effectiveness of of the supplement? effectiveness of of the supplement? effectiveness of of the supplement? >> Interestingly, I would say that the >> Interestingly, I would say that the >> Interestingly, I would say that the majority of omnivores probably aren't majority of omnivores probably aren't majority of omnivores probably aren't eating enough omega-3s either, right? eating enough omega-3s either, right? eating enough omega-3s either, right? Because they're just like people just Because they're just like people just Because they're just like people just aren't eating that much seafood. So, I aren't eating that much seafood. So, I aren't eating that much seafood. So, I think this is relevant to most people think this is relevant to most people think this is relevant to most people regardless. I will say that we and by we regardless. I will say that we and by we regardless. I will say that we and by we I mean like well-meaning health focused I mean like well-meaning health focused I mean like well-meaning health focused scientists like me, I think we've over scientists like me, I think we've over scientists like me, I think we've over complicated it a little bit, right? So complicated it a little bit, right? So complicated it a little bit, right? So the the the two main omega-3s that we the the the two main omega-3s that we the the the two main omega-3s that we might think about are Yeah. DHA and EPA. might think about are Yeah. DHA and EPA. might think about are Yeah. DHA and EPA. Uh there's also things like DPA which Uh there's also things like DPA which Uh there's also things like DPA which occurs in sort of smaller quantities. occurs in sort of smaller quantities. occurs in sort of smaller quantities. >> Here we go. >> Here we go. >> Here we go. >> Yeah. Right. So yeah, literally so like >> Yeah. Right. So yeah, literally so like >> Yeah. Right. So yeah, literally so like but but what I'll say is that like all but but what I'll say is that like all but but what I'll say is that like all of these are important. Most omega-3 of these are important. Most omega-3 of these are important. Most omega-3 supplements are going to contain DHA and supplements are going to contain DHA and supplements are going to contain DHA and EPA at a minimum, right? And that's EPA at a minimum, right? And that's EPA at a minimum, right? And that's where we have some evidence from like where we have some evidence from like where we have some evidence from like giving people these supplements. giving people these supplements. giving people these supplements. If you're not regularly consuming If you're not regularly consuming If you're not regularly consuming seafood, any kind of supplement, you seafood, any kind of supplement, you seafood, any kind of supplement, you know, and assuming like high quality, know, and assuming like high quality, know, and assuming like high quality, you get it from a good quality you get it from a good quality you get it from a good quality manufacturer, right? because these manufacturer, right? because these manufacturer, right? because these things can be, you know, poorly things can be, you know, poorly things can be, you know, poorly processed and they become rancid and processed and they become rancid and processed and they become rancid and oxidized and things like that. oxidized and things like that. oxidized and things like that. >> You know, assuming it's a reasonable >> You know, assuming it's a reasonable >> You know, assuming it's a reasonable quality supplement from a a respected uh quality supplement from a a respected uh quality supplement from a a respected uh manufacturer, manufacturer, manufacturer, something that gives you 1 to four grams something that gives you 1 to four grams something that gives you 1 to four grams of total DHA and EPA a day is probably of total DHA and EPA a day is probably of total DHA and EPA a day is probably good enough. Four matters much less. good enough. Four matters much less. good enough. Four matters much less. Like people have talked about Like people have talked about Like people have talked about triglyceride form versus phospholipid triglyceride form versus phospholipid triglyceride form versus phospholipid form and you get one in seafood and you form and you get one in seafood and you form and you get one in seafood and you get another in like um sort of krill and get another in like um sort of krill and get another in like um sort of krill and things like that things like that things like that >> or this is high in this but it it >> or this is high in this but it it >> or this is high in this but it it doesn't convert like there's this doesn't convert like there's this doesn't convert like there's this conversion thing right. conversion thing right. conversion thing right. >> Yes. Oh yeah. So the the conversion part >> Yes. Oh yeah. So the the conversion part >> Yes. Oh yeah. So the the conversion part is the is the shorter chain omega-3 is the is the shorter chain omega-3 is the is the shorter chain omega-3 fatty acids like ALA alpha lino alpha fatty acids like ALA alpha lino alpha fatty acids like ALA alpha lino alpha linic acid which is what you get in like linic acid which is what you get in like linic acid which is what you get in like chia seeds and walnuts and things like chia seeds and walnuts and things like chia seeds and walnuts and things like that. most people and actually um the that. most people and actually um the that. most people and actually um the conversion is worse in men on average conversion is worse in men on average conversion is worse in men on average than it is in women. Most people if if than it is in women. Most people if if than it is in women. Most people if if you only get omega-3s in that form, most you only get omega-3s in that form, most you only get omega-3s in that form, most people won't convert enough into the people won't convert enough into the people won't convert enough into the longchain form. So that's why you need longchain form. So that's why you need longchain form. So that's why you need to that's why you need to supplement. to that's why you need to supplement. to that's why you need to supplement. But I think in general, if you're But I think in general, if you're But I think in general, if you're getting a couple of grams of longchain getting a couple of grams of longchain getting a couple of grams of longchain omega-3s from a high quality supplement omega-3s from a high quality supplement omega-3s from a high quality supplement on average a day, right? That's it. I on average a day, right? That's it. I on average a day, right? That's it. I wouldn't worry so much about the ratios. wouldn't worry so much about the ratios. wouldn't worry so much about the ratios. wouldn't worry so much about the total wouldn't worry so much about the total wouldn't worry so much about the total amounts because you're then going to be amounts because you're then going to be amounts because you're then going to be ticking the boxes that you're that that ticking the boxes that you're that that ticking the boxes that you're that that you're close enough and you're also well you're close enough and you're also well you're close enough and you're also well beyond what most people are consuming. beyond what most people are consuming. beyond what most people are consuming. Then the easiest thing that you can do Then the easiest thing that you can do Then the easiest thing that you can do is measure something like an omega-3 is measure something like an omega-3 is measure something like an omega-3 index which just measures the amount of index which just measures the amount of index which just measures the amount of those in your blood and say am I close those in your blood and say am I close those in your blood and say am I close enough to a level that we know is enough to a level that we know is enough to a level that we know is associated with lower dementia risk associated with lower dementia risk associated with lower dementia risk which would be sort of 6 to 8%. Well, which would be sort of 6 to 8%. Well, which would be sort of 6 to 8%. Well, like above 6% maybe ideally above 8%. So like above 6% maybe ideally above 8%. So like above 6% maybe ideally above 8%. So maybe that simplified it a little bit. I maybe that simplified it a little bit. I maybe that simplified it a little bit. I think that um we we know that DHA and think that um we we know that DHA and think that um we we know that DHA and EPA are both important. You're going to EPA are both important. You're going to EPA are both important. You're going to get both from any supplement. The real get both from any supplement. The real get both from any supplement. The real problem is people consuming none. Like problem is people consuming none. Like problem is people consuming none. Like once you get to the threshold of once you get to the threshold of once you get to the threshold of consuming some like you more than a gram consuming some like you more than a gram consuming some like you more than a gram a day on average, right? You're already a day on average, right? You're already a day on average, right? You're already like in a much better bucket than than like in a much better bucket than than like in a much better bucket than than most other people. most other people. most other people. >> We're tiptoeing towards uh a longer >> We're tiptoeing towards uh a longer >> We're tiptoeing towards uh a longer discussion around supplements and what's discussion around supplements and what's discussion around supplements and what's effective and what isn't, what's effective and what isn't, what's effective and what isn't, what's nonsense. Um, but before we do that, nonsense. Um, but before we do that, nonsense. Um, but before we do that, while we're still on food, let's talk a while we're still on food, let's talk a while we're still on food, let's talk a little bit about the worst offenders. little bit about the worst offenders. little bit about the worst offenders. Obviously, we know ultrarocessed foods Obviously, we know ultrarocessed foods Obviously, we know ultrarocessed foods aren't good for us. Um, but aren't good for us. Um, but aren't good for us. Um, but what are some maybe less intuitively uh, what are some maybe less intuitively uh, what are some maybe less intuitively uh, you know, bad things that we should you know, bad things that we should you know, bad things that we should avoid? You'll notice that I work really avoid? You'll notice that I work really avoid? You'll notice that I work really hard to not like demonize anything in hard to not like demonize anything in hard to not like demonize anything in particular because it makes things particular because it makes things particular because it makes things tricky cognitively for people and like tricky cognitively for people and like tricky cognitively for people and like nothing is black and white. Um so I I'll nothing is black and white. Um so I I'll nothing is black and white. Um so I I'll give one broad example which is that uh give one broad example which is that uh give one broad example which is that uh the levels of homocyine in the US in the levels of homocyine in the US in the levels of homocyine in the US in general particularly high homocyine general particularly high homocyine general particularly high homocyine which is a so like above 13 which is which is a so like above 13 which is which is a so like above 13 which is associated with increased risk of associated with increased risk of associated with increased risk of dementia that significantly improved dementia that significantly improved dementia that significantly improved since we started to fortify flour with since we started to fortify flour with since we started to fortify flour with folic acid in in 1998. heavily processed folic acid in in 1998. heavily processed folic acid in in 1998. heavily processed foods can can almost be beneficial in foods can can almost be beneficial in foods can can almost be beneficial in one way because it allows us to add back one way because it allows us to add back one way because it allows us to add back nutrients that the population is is nutrients that the population is is nutrients that the population is is missing, right? Um, but missing, right? Um, but missing, right? Um, but in general, I think the, you know, in general, I think the, you know, in general, I think the, you know, anything that's full of refined fat or anything that's full of refined fat or anything that's full of refined fat or refined carbohydrate that's so calorie refined carbohydrate that's so calorie refined carbohydrate that's so calorie dense and nutrient poor. So that's, you dense and nutrient poor. So that's, you dense and nutrient poor. So that's, you know, kind of all of the the baked know, kind of all of the the baked know, kind of all of the the baked goods, snacked good like snack goods, goods, snacked good like snack goods, goods, snacked good like snack goods, things that are you very easy to things that are you very easy to things that are you very easy to overeat. um and are designed to you know overeat. um and are designed to you know overeat. um and are designed to you know for that to be the case. Um it's not for that to be the case. Um it's not for that to be the case. Um it's not that you can't include these and it's that you can't include these and it's that you can't include these and it's not like I avoid those things completely not like I avoid those things completely not like I avoid those things completely but you have to think about them in that but you have to think about them in that but you have to think about them in that goal of overall energy you know balance goal of overall energy you know balance goal of overall energy you know balance and nutrient intake. So like you're and nutrient intake. So like you're and nutrient intake. So like you're eating more of those things you're eating more of those things you're eating more of those things you're you're sort of like pulling away from you're sort of like pulling away from you're sort of like pulling away from your nutrient goals and you're also kind your nutrient goals and you're also kind your nutrient goals and you're also kind of heading towards the risk of of of heading towards the risk of of of heading towards the risk of of overeating. So that like that kind of um overeating. So that like that kind of um overeating. So that like that kind of um yeah the the heavily processed yeah the the heavily processed yeah the the heavily processed carbohydrates and fats are usually where carbohydrates and fats are usually where carbohydrates and fats are usually where things get trickiest. Um so you know things get trickiest. Um so you know things get trickiest. Um so you know fried foods uh baked goods uh sweets fried foods uh baked goods uh sweets fried foods uh baked goods uh sweets sodas that you know sugar sweet and sodas that you know sugar sweet and sodas that you know sugar sweet and sodas that that kind of stuff. Then a sodas that that kind of stuff. Then a sodas that that kind of stuff. Then a big trap that's now easy to fall into is big trap that's now easy to fall into is big trap that's now easy to fall into is when some something's like hey eat these when some something's like hey eat these when some something's like hey eat these protein like Doritos or eat eat this protein like Doritos or eat eat this protein like Doritos or eat eat this protein candy bar. it's still a candy protein candy bar. it's still a candy protein candy bar. it's still a candy bar. Um they've added a little bit more bar. Um they've added a little bit more bar. Um they've added a little bit more protein, but it's not getting to the protein, but it's not getting to the protein, but it's not getting to the point where it's actually going to point where it's actually going to point where it's actually going to meaningfully move the needle and you're meaningfully move the needle and you're meaningfully move the needle and you're very likely to overeat it. Uh same for very likely to overeat it. Uh same for very likely to overeat it. Uh same for Oh, hey, these these um these brownies Oh, hey, these these um these brownies Oh, hey, these these um these brownies are keto or these brownies are like are keto or these brownies are like are keto or these brownies are like plant-based or vegan, right? They're plant-based or vegan, right? They're plant-based or vegan, right? They're still brownies, right? still brownies, right? still brownies, right? >> Yeah. And they still have, you know, 900 >> Yeah. And they still have, you know, 900 >> Yeah. And they still have, you know, 900 calories or something like that. Setting calories or something like that. Setting calories or something like that. Setting aside the keto thing, like sugar aside the keto thing, like sugar aside the keto thing, like sugar >> Yeah. I mean you can kind of I know you >> Yeah. I mean you can kind of I know you >> Yeah. I mean you can kind of I know you don't want to vilify any one thing but don't want to vilify any one thing but don't want to vilify any one thing but you know is there really a place for you know is there really a place for you know is there really a place for refined sugar in any kind of healthy refined sugar in any kind of healthy refined sugar in any kind of healthy diet diet diet >> in the context of all those other things >> in the context of all those other things >> in the context of all those other things like occasionally consuming sugar is is like occasionally consuming sugar is is like occasionally consuming sugar is is fine right but you have to maintain fine right but you have to maintain fine right but you have to maintain those those other those other components those those other those other components those those other those other components um and it's it's likely that if you're um and it's it's likely that if you're um and it's it's likely that if you're consuming sugar at the level that's consuming sugar at the level that's consuming sugar at the level that's going to be associated with overeating going to be associated with overeating going to be associated with overeating um you know and these other like um you know and these other like um you know and these other like metabolic health conditions um you're metabolic health conditions um you're metabolic health conditions um you're very unlikely attending to those two very unlikely attending to those two very unlikely attending to those two things. So, it is possible to, you know, things. So, it is possible to, you know, things. So, it is possible to, you know, occasionally consume sugar, be in like occasionally consume sugar, be in like occasionally consume sugar, be in like be in a good energy state and and be in a good energy state and and be in a good energy state and and overall have a very nutrient-dense diet. overall have a very nutrient-dense diet. overall have a very nutrient-dense diet. It's just that the more you shift in It's just that the more you shift in It's just that the more you shift in that direction, the harder those things that direction, the harder those things that direction, the harder those things those those things become. So, those those things become. So, those those things become. So, >> you know, I will occasionally eat >> you know, I will occasionally eat >> you know, I will occasionally eat dessert. I don't I'm not particularly dessert. I don't I'm not particularly dessert. I don't I'm not particularly sweet tooth, so I don't eat a ton of it, sweet tooth, so I don't eat a ton of it, sweet tooth, so I don't eat a ton of it, right? But because I know I've got those right? But because I know I've got those right? But because I know I've got those other things handled, I'm less concerned other things handled, I'm less concerned other things handled, I'm less concerned about it. So what you often see is that about it. So what you often see is that about it. So what you often see is that particularly as you get to like particularly as you get to like particularly as you get to like processed or packaged foods, something processed or packaged foods, something processed or packaged foods, something will be sold as like low sugar, but it's will be sold as like low sugar, but it's will be sold as like low sugar, but it's still energy dense, it's still nutrient still energy dense, it's still nutrient still energy dense, it's still nutrient poor, that kind. So like poor, that kind. So like poor, that kind. So like >> it becomes a thing where we can go, oh, >> it becomes a thing where we can go, oh, >> it becomes a thing where we can go, oh, there's no sugar in this, but actually there's no sugar in this, but actually there's no sugar in this, but actually it it doesn't make it any healthier. it it doesn't make it any healthier. it it doesn't make it any healthier. >> Um, so that's that's why, you know, >> Um, so that's that's why, you know, >> Um, so that's that's why, you know, again, we become kind of over over again, we become kind of over over again, we become kind of over over reductionist. Um, so not something that reductionist. Um, so not something that reductionist. Um, so not something that I think that you have to completely I think that you have to completely I think that you have to completely avoid, but the more you're consuming of avoid, but the more you're consuming of avoid, but the more you're consuming of it, the less you're likely to kind of it, the less you're likely to kind of it, the less you're likely to kind of hit those other things that we know are hit those other things that we know are hit those other things that we know are critically important. critically important. critically important. >> Sure.

And it's like I couldn't sleep tonight. And it's like I couldn't sleep tonight. And it's like how resilient are you actually if you're how resilient are you actually if you're how resilient are you actually if you're so disregulated by this, you know, this so disregulated by this, you know, this so disregulated by this, you know, this one kind of like indulgence. one kind of like indulgence. one kind of like indulgence. >> The I think that's a really I think >> The I think that's a really I think >> The I think that's a really I think that's a really important point and I that's a really important point and I that's a really important point and I would my guess is that so so yeah like would my guess is that so so yeah like would my guess is that so so yeah like your we know that your gut microbiome your we know that your gut microbiome your we know that your gut microbiome will kind of adapt to the foods that you will kind of adapt to the foods that you will kind of adapt to the foods that you regularly give it. So like if you give regularly give it. So like if you give regularly give it. So like if you give some so like you know I had family some so like you know I had family some so like you know I had family members who were vegetarian for a long members who were vegetarian for a long members who were vegetarian for a long period of time and then you know it's period of time and then you know it's period of time and then you know it's sort of harder for them to eat meat sort of harder for them to eat meat sort of harder for them to eat meat later because their body just hasn't later because their body just hasn't later because their body just hasn't adapted to it right and we know that adapted to it right and we know that adapted to it right and we know that there's some shifts that can happen in there's some shifts that can happen in there's some shifts that can happen in the gut to kind of support that. Um and the gut to kind of support that. Um and the gut to kind of support that. Um and so the same might be for large boluses so the same might be for large boluses so the same might be for large boluses of of sugar. Um, but I think a lot of of of sugar. Um, but I think a lot of of of sugar. Um, but I think a lot of where that comes from is because and where that comes from is because and where that comes from is because and we've we've made this worse with the uh we've we've made this worse with the uh we've we've made this worse with the uh advent of like continuous glucose advent of like continuous glucose advent of like continuous glucose monitors and stuff like that is you're monitors and stuff like that is you're monitors and stuff like that is you're like I know this is bad and I expect it like I know this is bad and I expect it like I know this is bad and I expect it to be bad and therefore I feel bad to be bad and therefore I feel bad to be bad and therefore I feel bad because of it.

The um so so one example that we >> Yeah. The um so so one example that we >> Yeah. The um so so one example that we have that that you can use here is have that that you can use here is have that that you can use here is there's a study by Ellen Langanger which there's a study by Ellen Langanger which there's a study by Ellen Langanger which um looked at diabetics and you brought um looked at diabetics and you brought um looked at diabetics and you brought them into the lab and because they're them into the lab and because they're them into the lab and because they're they're diabetic um they're obviously they're diabetic um they're obviously they're diabetic um they're obviously very cognizant of their sugar and and very cognizant of their sugar and and very cognizant of their sugar and and carbohydrate intake. They brought carbohydrate intake. They brought carbohydrate intake. They brought individuals into the lab and they gave individuals into the lab and they gave individuals into the lab and they gave them a milkshake and they like look at them a milkshake and they like look at them a milkshake and they like look at the look at the um um the nutrients on the look at the um um the nutrients on the look at the um um the nutrients on this on this milkshake. There was a high this on this milkshake. There was a high this on this milkshake. There was a high sugar milkshake and and a low sugar sugar milkshake and and a low sugar sugar milkshake and and a low sugar milkshake and then they measured their milkshake and then they measured their milkshake and then they measured their blood sugar and the blood sugar was much blood sugar and the blood sugar was much blood sugar and the blood sugar was much higher after the high sugar milkshake higher after the high sugar milkshake higher after the high sugar milkshake than the low sugar milkshake. Like of than the low sugar milkshake. Like of than the low sugar milkshake. Like of course as you'd expect the problem is course as you'd expect the problem is course as you'd expect the problem is this is the same milkshake. this is the same milkshake. this is the same milkshake. >> So the stress of anticipating a blood >> So the stress of anticipating a blood >> So the stress of anticipating a blood sugar spike which they know is going to sugar spike which they know is going to sugar spike which they know is going to affect their health, right? drove their affect their health, right? drove their affect their health, right? drove their blood sugar up even higher. Um, and so blood sugar up even higher. Um, and so blood sugar up even higher. Um, and so this is, you know, every time we this is, you know, every time we this is, you know, every time we approach anything like this and we think approach anything like this and we think approach anything like this and we think about um, this is going to be this is about um, this is going to be this is about um, this is going to be this is going to be bad for me. This is going to going to be bad for me. This is going to going to be bad for me. This is going to be, you know, you might get some be, you know, you might get some be, you know, you might get some benefit, you think it's going to be good benefit, you think it's going to be good benefit, you think it's going to be good for you. But in general, we see that if for you. But in general, we see that if for you. But in general, we see that if we think something's going to be good we think something's going to be good we think something's going to be good for us, it has like a neutral effect. If for us, it has like a neutral effect. If for us, it has like a neutral effect. If we think something is going to be bad we think something is going to be bad we think something is going to be bad for us, it has like a like a negative a for us, it has like a like a negative a for us, it has like a like a negative a negative effect. This then uh translates negative effect. This then uh translates negative effect. This then uh translates to all the other ways that we can think to all the other ways that we can think to all the other ways that we can think about health information. So I mentioned about health information. So I mentioned about health information. So I mentioned earlier that thinking that you're earlier that thinking that you're earlier that thinking that you're constantly um not doing enough can constantly um not doing enough can constantly um not doing enough can negatively impact your health. And there negatively impact your health. And there negatively impact your health. And there are some studies that suggest that when are some studies that suggest that when are some studies that suggest that when you ask people how much exercise they're you ask people how much exercise they're you ask people how much exercise they're doing compared to people like them and doing compared to people like them and doing compared to people like them and you look at um those who think they're you look at um those who think they're you look at um those who think they're doing less than less exercise than doing less than less exercise than doing less than less exercise than people like them, as much exercise as people like them, as much exercise as people like them, as much exercise as people like them, or more exercise than people like them, or more exercise than people like them, or more exercise than people like them. People who think people like them. People who think people like them. People who think they're doing more exercise than people they're doing more exercise than people they're doing more exercise than people like them tend to live longer and they like them tend to live longer and they like them tend to live longer and they have better cognitive function. However, have better cognitive function. However, have better cognitive function. However, this is after you adjust for how much this is after you adjust for how much this is after you adjust for how much exercise these people are actually doing exercise these people are actually doing exercise these people are actually doing and they have like um they use like and they have like um they use like and they have like um they use like activity monitors, right? So, there's activity monitors, right? So, there's activity monitors, right? So, there's this there's and the people who think this there's and the people who think this there's and the people who think they're doing less end up having like they're doing less end up having like they're doing less end up having like worse. worse. worse. >> If you're just a narcissistic sociopath >> If you're just a narcissistic sociopath >> If you're just a narcissistic sociopath who thinks you're better than everybody, who thinks you're better than everybody, who thinks you're better than everybody, you're you're you're >> there's something screwed up. >> there's something screwed up. >> there's something screwed up. >> Actually, there's like true. It's like >> Actually, there's like true. It's like >> Actually, there's like true. It's like your mind is creating your reality and your mind is creating your reality and your mind is creating your reality and if you're like I'm doing great if you're like I'm doing great if you're like I'm doing great >> then you are creating you know your own >> then you are creating you know your own >> then you are creating you know your own version of greatness in your life version of greatness in your life version of greatness in your life >> to to an extent. So there is some >> to to an extent. So there is some >> to to an extent. So there is some benefit of this sort of like ignorance benefit of this sort of like ignorance benefit of this sort of like ignorance ignorance is bliss almost right. So like ignorance is bliss almost right. So like ignorance is bliss almost right. So like this is the and you you've already said this is the and you you've already said this is the and you you've already said this like this is the risk that we run this like this is the risk that we run this like this is the risk that we run by sort of overanalyzing health and by sort of overanalyzing health and by sort of overanalyzing health and lifestyle lifestyle lifestyle >> because everybody's walking around let's >> because everybody's walking around let's >> because everybody's walking around let's face it everybody's walking around face it everybody's walking around face it everybody's walking around thinking they're not doing enough and thinking they're not doing enough and thinking they're not doing enough and they're falling short. Yeah, they're falling short. Yeah, they're falling short. Yeah, >> if you have a social media account and >> if you have a social media account and >> if you have a social media account and any kind of fitness or nutrition stuff any kind of fitness or nutrition stuff any kind of fitness or nutrition stuff happens to come up, happens to come up, happens to come up, >> we're all judging ourselves against some >> we're all judging ourselves against some >> we're all judging ourselves against some imaginary standard that we're not even imaginary standard that we're not even imaginary standard that we're not even close to living up to. So, every choice close to living up to. So, every choice close to living up to. So, every choice that we make is a choice of falling that we make is a choice of falling that we make is a choice of falling short of what we feel like we should or short of what we feel like we should or short of what we feel like we should or could be doing. And so, when you could be doing. And so, when you could be doing. And so, when you aggregate that over time, what is that aggregate that over time, what is that aggregate that over time, what is that doing to our mindset? We're always in a doing to our mindset? We're always in a doing to our mindset? We're always in a place of lack. Mhm. When you look at place of lack. Mhm. When you look at place of lack. Mhm. When you look at things like uh self-compassion things like uh self-compassion things like uh self-compassion um which you can break you break down um which you can break you break down um which you can break you break down into multiple components of self into multiple components of self into multiple components of self self-kindness u mindfulness and common self-kindness u mindfulness and common self-kindness u mindfulness and common common humanity. You see that and this common humanity. You see that and this common humanity. You see that and this is relevant again to like athletes and is relevant again to like athletes and is relevant again to like athletes and to and to to like the health of the to and to to like the health of the to and to to like the health of the general population. Um athletes who are general population. Um athletes who are general population. Um athletes who are more self-compassionate tend to be more more self-compassionate tend to be more more self-compassionate tend to be more resilient and tend to perform better resilient and tend to perform better resilient and tend to perform better over long periods of time because they over long periods of time because they over long periods of time because they understand the nature of setbacks. They understand the nature of setbacks. They understand the nature of setbacks. They understand that we're just humans and understand that we're just humans and understand that we're just humans and they treat themselves like they would they treat themselves like they would they treat themselves like they would treat other people and then that allows treat other people and then that allows treat other people and then that allows them to learn, do better, come back and them to learn, do better, come back and them to learn, do better, come back and and perform again. People who are and perform again. People who are and perform again. People who are self-compassionate in the chronic self-compassionate in the chronic self-compassionate in the chronic disease setting tend to have better disease setting tend to have better disease setting tend to have better health outcomes for the same reason, health outcomes for the same reason, health outcomes for the same reason, right? They understand that, oh, you right? They understand that, oh, you right? They understand that, oh, you know, I didn't necessarily eat the way I know, I didn't necessarily eat the way I know, I didn't necessarily eat the way I that I, you know, would normally do or that I, you know, would normally do or that I, you know, would normally do or that I I didn't sleep or exercise the that I I didn't sleep or exercise the that I I didn't sleep or exercise the way I normally would, but do you know way I normally would, but do you know way I normally would, but do you know what? I'm human. I'm going to come back what? I'm human. I'm going to come back what? I'm human. I'm going to come back and I'm going to do it better next time. and I'm going to do it better next time. and I'm going to do it better next time. And like overall they tend to see uh you And like overall they tend to see uh you And like overall they tend to see uh you know when they do uh interventions that know when they do uh interventions that know when they do uh interventions that improve self-compassion they tend to see improve self-compassion they tend to see improve self-compassion they tend to see better health outcomes. So like better better health outcomes. So like better better health outcomes. So like better blood sugar and blood pressure in blood sugar and blood pressure in blood sugar and blood pressure in diabetics who are kind of taught about diabetics who are kind of taught about diabetics who are kind of taught about self-compassion. So um what we're kind self-compassion. So um what we're kind self-compassion. So um what we're kind of told which is that we always need to of told which is that we always need to of told which is that we always need to do better. We always need to be telling do better. We always need to be telling do better. We always need to be telling ourselves we're not doing enough. we ourselves we're not doing enough. we ourselves we're not doing enough. we always need to be pushing through, always need to be pushing through, always need to be pushing through, right? It's actually the exact opposite right? It's actually the exact opposite right? It's actually the exact opposite of what creates um a sustainable and of what creates um a sustainable and of what creates um a sustainable and well-being supporting mindset, which is well-being supporting mindset, which is well-being supporting mindset, which is that yes, I know I can improve. Yes, I that yes, I know I can improve. Yes, I that yes, I know I can improve. Yes, I know there are these things that I can know there are these things that I can know there are these things that I can do, and I'm going to celebrate the wi do, and I'm going to celebrate the wi do, and I'm going to celebrate the wi like my wins. I'm going to celebrate. like my wins. I'm going to celebrate. like my wins. I'm going to celebrate. I'm going to enjoy that feeling of I'm going to enjoy that feeling of I'm going to enjoy that feeling of discomfort. I'm going to enjoy the fact discomfort. I'm going to enjoy the fact discomfort. I'm going to enjoy the fact that these things are improving, but that these things are improving, but that these things are improving, but acknowledge that you can't make acknowledge that you can't make acknowledge that you can't make everything perfect. You can't optimize everything perfect. You can't optimize everything perfect. You can't optimize everything. Um and, you know, we'll everything. Um and, you know, we'll everything. Um and, you know, we'll slowly get better over time. And then slowly get better over time. And then slowly get better over time. And then not only are you engaging with the not only are you engaging with the not only are you engaging with the things um that you know will improve things um that you know will improve things um that you know will improve your health, but you're also maximizing your health, but you're also maximizing your health, but you're also maximizing the likelihood that you'll benefit from the likelihood that you'll benefit from the likelihood that you'll benefit from them because you're not spending the them because you're not spending the them because you're not spending the rest of your time beating beating rest of your time beating beating rest of your time beating beating yourself up that you're not doing even yourself up that you're not doing even yourself up that you're not doing even more. more. more. >> I feel like you just said the quiet part >> I feel like you just said the quiet part >> I feel like you just said the quiet part out loud. And perhaps the most out loud. And perhaps the most out loud. And perhaps the most underappreciated underappreciated underappreciated aspect of of all of this, not just for aspect of of all of this, not just for aspect of of all of this, not just for brain health, but overall health in this brain health, but overall health in this brain health, but overall health in this epidemic of loneliness and isolation and epidemic of loneliness and isolation and epidemic of loneliness and isolation and disconnection and, you know, kind of a disconnection and, you know, kind of a disconnection and, you know, kind of a decline in our overall, you know, mental decline in our overall, you know, mental decline in our overall, you know, mental health from on a population level. A lot health from on a population level. A lot health from on a population level. A lot of it stems towards this sense that of it stems towards this sense that of it stems towards this sense that we're not enough. You know, that we're u we're not enough.

Um absolutely one of >> Yeah. Incredible. Um absolutely one of my all-time favorite scientists. Um but my all-time favorite scientists. Um but my all-time favorite scientists. Um but where I think we have solid evidence is where I think we have solid evidence is where I think we have solid evidence is is essentially the stuff that we've is essentially the stuff that we've is essentially the stuff that we've already talked about is um attending to already talked about is um attending to already talked about is um attending to nutrient status for nutrients that we nutrient status for nutrients that we nutrient status for nutrients that we know are critical for brain health that know are critical for brain health that know are critical for brain health that are either deficient or insufficient in are either deficient or insufficient in are either deficient or insufficient in the diet. And we know that the majority the diet. And we know that the majority the diet. And we know that the majority of adults around the world are deficient of adults around the world are deficient of adults around the world are deficient in at least one nutrient. So finding in at least one nutrient. So finding in at least one nutrient. So finding some way to attend to that. So it's some way to attend to that. So it's some way to attend to that. So it's supplementing with vitamin D if you supplementing with vitamin D if you supplementing with vitamin D if you need. need. need. >> So if somebody is to go and get a blood >> So if somebody is to go and get a blood >> So if somebody is to go and get a blood panel done, what are the markers that panel done, what are the markers that panel done, what are the markers that you would like them to pay attention to? you would like them to pay attention to? you would like them to pay attention to? >> Again, the ones that we have the best >> Again, the ones that we have the best >> Again, the ones that we have the best evidence for. So vitamin D. Um you evidence for. So vitamin D. Um you evidence for. So vitamin D. Um you definitely don't want to be deficient, definitely don't want to be deficient, definitely don't want to be deficient, which is less than 20 less than 20 which is less than 20 less than 20 which is less than 20 less than 20 nanogs per mill. Um but you ideally nanogs per mill. Um but you ideally nanogs per mill. Um but you ideally you're at least above 30. Um probably you're at least above 30. Um probably you're at least above 30. Um probably above 40 is is best. 40 to 60 is above 40 is is best. 40 to 60 is above 40 is is best. 40 to 60 is probably a good target range. I was probably a good target range. I was probably a good target range. I was below and I started like sort of mega below and I started like sort of mega below and I started like sort of mega dozing on vitamin D and then my levels dozing on vitamin D and then my levels dozing on vitamin D and then my levels were like way too high were like way too high were like way too high >> and I was struggling to sleep and then I >> and I was struggling to sleep and then I >> and I was struggling to sleep and then I realized like oh excess vitamin D can realized like oh excess vitamin D can realized like oh excess vitamin D can impair sleep and so yeah this is and I impair sleep and so yeah this is and I impair sleep and so yeah this is and I say this just because say this just because say this just because >> more is not always better and you know >> more is not always better and you know >> more is not always better and you know you have to like you know really gauge you have to like you know really gauge you have to like you know really gauge how you're managing your supplementation how you're managing your supplementation how you're managing your supplementation even if you're trying to make up for you even if you're trying to make up for you even if you're trying to make up for you know a shortage or a low level. know a shortage or a low level. know a shortage or a low level. >> Yeah, absolutely. So, and vitamin D is >> Yeah, absolutely. So, and vitamin D is >> Yeah, absolutely. So, and vitamin D is one of the ones where it's because it's one of the ones where it's because it's one of the ones where it's because it's fat soluble, it's easy to take too much, fat soluble, it's easy to take too much, fat soluble, it's easy to take too much, especially if you're taking like several especially if you're taking like several especially if you're taking like several thousand daily for long periods of time. thousand daily for long periods of time. thousand daily for long periods of time. So, yeah, definitely get above 20, maybe So, yeah, definitely get above 20, maybe So, yeah, definitely get above 20, maybe target 40 to 60 homocyine for for B target 40 to 60 homocyine for for B target 40 to 60 homocyine for for B vitamins. Um, then like I said, vitamins. Um, then like I said, vitamins. Um, then like I said, definitely less than 13, ideally less definitely less than 13, ideally less definitely less than 13, ideally less than ideally less than 10. Um and if than ideally less than 10. Um and if than ideally less than 10. Um and if homoyine is elevated then those B homoyine is elevated then those B homoyine is elevated then those B vitamins I mentioned earlier the the vitamins I mentioned earlier the the vitamins I mentioned earlier the the ones that they usually um give in in ones that they usually um give in in ones that they usually um give in in clinical trials is uh B12 and folate. Um clinical trials is uh B12 and folate. Um clinical trials is uh B12 and folate. Um but you might also add B6 and riop and but you might also add B6 and riop and but you might also add B6 and riop and rioplavin. Um other things that can rioplavin. Um other things that can rioplavin. Um other things that can bring down homocyine might include bring down homocyine might include bring down homocyine might include creatine betane or trimethoglycine um creatine betane or trimethoglycine um creatine betane or trimethoglycine um potentially choline too. Then you might potentially choline too. Then you might potentially choline too. Then you might think about that you know are you do you think about that you know are you do you think about that you know are you do you have a diet that includes those things have a diet that includes those things have a diet that includes those things right? Betane is high in beets and coden right? Betane is high in beets and coden right? Betane is high in beets and coden is high in eggs and creatine is is is um is high in eggs and creatine is is is um is high in eggs and creatine is is is um high in meat and fish, high in meat and fish, high in meat and fish, >> right? So that might might help help you >> right? So that might might help help you >> right? So that might might help help you sort of like target any supplementation sort of like target any supplementation sort of like target any supplementation if you need it. if you need it. if you need it. >> Um iron status is is really critical. Um >> Um iron status is is really critical. Um >> Um iron status is is really critical. Um so you would normally just measure so you would normally just measure so you would normally just measure hemoglobin level, but then there are a hemoglobin level, but then there are a hemoglobin level, but then there are a whole bunch of iron metrics that you whole bunch of iron metrics that you whole bunch of iron metrics that you take along the side to kind of help you take along the side to kind of help you take along the side to kind of help you interpret it. So like feritin, transfer interpret it. So like feritin, transfer interpret it. So like feritin, transfer saturation, um iron binding capacity, saturation, um iron binding capacity, saturation, um iron binding capacity, but ideally sort of women want their but ideally sort of women want their but ideally sort of women want their hemoglobin to be at least above 12.5. um hemoglobin to be at least above 12.5. um hemoglobin to be at least above 12.5. um men 13.5 men 13.5 men 13.5 um but not too high. So if you're if um but not too high. So if you're if um but not too high. So if you're if you're like in men a hemoglobin above 17 you're like in men a hemoglobin above 17 you're like in men a hemoglobin above 17 or in women a hemoglobin above 16 makes or in women a hemoglobin above 16 makes or in women a hemoglobin above 16 makes it much more likely that you have it much more likely that you have it much more likely that you have something like especially if you're something like especially if you're something like especially if you're older or you have some elements of older or you have some elements of older or you have some elements of metabolic syndrome makes it likely that metabolic syndrome makes it likely that metabolic syndrome makes it likely that you have something like obstructive you have something like obstructive you have something like obstructive sleep apnnea. Um when you stop breathing sleep apnnea. Um when you stop breathing sleep apnnea. Um when you stop breathing during the night your oxygen levels drop during the night your oxygen levels drop during the night your oxygen levels drop and your body makes more hemoglobin in and your body makes more hemoglobin in and your body makes more hemoglobin in response. Um, so cuz we know obstructive response. Um, so cuz we know obstructive response. Um, so cuz we know obstructive sleep apnnea and other sleep disordered sleep apnnea and other sleep disordered sleep apnnea and other sleep disordered breathing is a risk factor for dementia. breathing is a risk factor for dementia. breathing is a risk factor for dementia. Another reason to check your hemoglobin Another reason to check your hemoglobin Another reason to check your hemoglobin is because at the high end and that's is because at the high end and that's is because at the high end and that's something that you need to address um as something that you need to address um as something that you need to address um as well. Yeah, we already talked about well. Yeah, we already talked about well. Yeah, we already talked about omega-3 status. So um omega-3 index if omega-3 status. So um omega-3 index if omega-3 status. So um omega-3 index if you you can get it um doctors will do you you can get it um doctors will do you you can get it um doctors will do most of the other things that I most of the other things that I most of the other things that I mentioned. Um you can u just get like an mentioned. Um you can u just get like an mentioned. Um you can u just get like an at home test for omega-3 index if you at home test for omega-3 index if you at home test for omega-3 index if you can't get it through your physician. Um can't get it through your physician. Um can't get it through your physician. Um so at least above six, ideally above 8%. so at least above six, ideally above 8%. so at least above six, ideally above 8%. Um and then um other things that they're Um and then um other things that they're Um and then um other things that they're important um can be harder to test. So important um can be harder to test. So important um can be harder to test. So like it's really hard to test magnesium like it's really hard to test magnesium like it's really hard to test magnesium status for for example, but um magnesium status for for example, but um magnesium status for for example, but um magnesium tends to be something that people don't tends to be something that people don't tends to be something that people don't get much of or get enough of. And we get much of or get enough of. And we get much of or get enough of. And we know that people who who sweat a lot or know that people who who sweat a lot or know that people who who sweat a lot or who are athletes tend to need more who are athletes tend to need more who are athletes tend to need more magnesium. So a safe recommendation is magnesium. So a safe recommendation is magnesium. So a safe recommendation is often to think about um a magnesium often to think about um a magnesium often to think about um a magnesium supplement especially if you're if supplement especially if you're if supplement especially if you're if you're an athlete um so and that you're an athlete um so and that you're an athlete um so and that particularly for people who struggle particularly for people who struggle particularly for people who struggle with sleep there's increasing evidence with sleep there's increasing evidence with sleep there's increasing evidence that taking magnesium at night can can that taking magnesium at night can can that taking magnesium at night can can help to improve sleep. other things help to improve sleep. other things help to improve sleep. other things especially as as we sort of get into um especially as as we sort of get into um especially as as we sort of get into um some element of aging or cognitive some element of aging or cognitive some element of aging or cognitive decline there's some evidence for decline there's some evidence for decline there's some evidence for choline which had already um previously choline which had already um previously choline which had already um previously mentioned uh that may may be beneficial mentioned uh that may may be beneficial mentioned uh that may may be beneficial but even even then that's sort of like but even even then that's sort of like but even even then that's sort of like well apart from those others I think the well apart from those others I think the well apart from those others I think the the kind of the core vitamins are where the kind of the core vitamins are where the kind of the core vitamins are where where we have the and nutrients is where where we have the and nutrients is where where we have the and nutrients is where we have have the best evidence um then we have have the best evidence um then we have have the best evidence um then beyond that it might become very context beyond that it might become very context beyond that it might become very context dependent and there's very few things dependent and there's very few things dependent and there's very few things that I would give a blanket uh that I would give a blanket uh that I would give a blanket uh recommendation for if you're getting recommendation for if you're getting recommendation for if you're getting those blood tests, you're you're those blood tests, you're you're those blood tests, you're you're addressing those um nutrient addressing those um nutrient addressing those um nutrient requirements and then you're also, you requirements and then you're also, you requirements and then you're also, you know, testing your blood pressure, know, testing your blood pressure, know, testing your blood pressure, testing your blood sugar, testing your testing your blood sugar, testing your testing your blood sugar, testing your cardiovascular risk through your lipids, cardiovascular risk through your lipids, cardiovascular risk through your lipids, like that's the big bulk of of risk like that's the big bulk of of risk like that's the big bulk of of risk right there. Um, anything else is going right there. Um, anything else is going right there. Um, anything else is going to be, like you kind of said, like sort to be, like you kind of said, like sort to be, like you kind of said, like sort of like cherry on the top. of like cherry on the top. of like cherry on the top. >> Creatine has been in the news lately. >> Creatine has been in the news lately. >> Creatine has been in the news lately. >> Uh, it went from being this thing that >> Uh, it went from being this thing that >> Uh, it went from being this thing that only bodybuilders use to sort of only bodybuilders use to sort of only bodybuilders use to sort of mainstream adoption. uh but in limited mainstream adoption. uh but in limited mainstream adoption. uh but in limited amounts, five grams a day, maybe 10 amounts, five grams a day, maybe 10 amounts, five grams a day, maybe 10 grams a day. Now we're seeing this grams a day. Now we're seeing this grams a day. Now we're seeing this science emerge around the relationship science emerge around the relationship science emerge around the relationship between creatine intake and brain between creatine intake and brain between creatine intake and brain health. And you know, every time I open health. And you know, every time I open health. And you know, every time I open up my social media feed, the daily up my social media feed, the daily up my social media feed, the daily recommended intake increases. It was 10, recommended intake increases. It was 10, recommended intake increases. It was 10, then it was 20. I've seen people saying then it was 20. I've seen people saying then it was 20. I've seen people saying you should be taking 30 grams of this a you should be taking 30 grams of this a you should be taking 30 grams of this a day. What say you, sir? day. What say you, sir? day. What say you, sir? >> So, creatine is the only supplement >> So, creatine is the only supplement >> So, creatine is the only supplement outside of those vitamins and minerals outside of those vitamins and minerals outside of those vitamins and minerals that I mentioned that I actually that I mentioned that I actually that I mentioned that I actually mentioned in my book. Not because I I mentioned in my book. Not because I I mentioned in my book. Not because I I don't think it's I don't think it's don't think it's I don't think it's don't think it's I don't think it's magic, but there is an increasing burden magic, but there is an increasing burden magic, but there is an increasing burden of evidence that it's that it does of evidence that it's that it does of evidence that it's that it does interesting things for the brain. interesting things for the brain. interesting things for the brain. There's some studies after concussion There's some studies after concussion There's some studies after concussion where it may improve recovery. There's where it may improve recovery. There's where it may improve recovery. There's studies in the setting of uh studies in the setting of uh studies in the setting of uh particularly in older adults or what particularly in older adults or what particularly in older adults or what those started to experience cognitive those started to experience cognitive those started to experience cognitive decline, creatine supplementation may decline, creatine supplementation may decline, creatine supplementation may improve memory. uh in in particular um improve memory. uh in in particular um improve memory. uh in in particular um it seems to help improve um cognitive it seems to help improve um cognitive it seems to help improve um cognitive function in the setting of sleep function in the setting of sleep function in the setting of sleep deprivation deprivation deprivation um and now there are several trials um and now there are several trials um and now there are several trials where they've added creatine to where they've added creatine to where they've added creatine to anti-depressants in the setting of anti-depressants in the setting of anti-depressants in the setting of treatment treating depression and it treatment treating depression and it treatment treating depression and it seems to provide additional benefit seems to provide additional benefit seems to provide additional benefit >> um so I think it does lots of >> um so I think it does lots of >> um so I think it does lots of interesting things for the brain it's interesting things for the brain it's interesting things for the brain it's also the best studied supplement and also the best studied supplement and also the best studied supplement and because you know 5 to 10 grams of because you know 5 to 10 grams of because you know 5 to 10 grams of creatine which is a fairly standard dose creatine which is a fairly standard dose creatine which is a fairly standard dose even five grams is sort of like longterm even five grams is sort of like longterm even five grams is sort of like longterm the standard dose you could achieve that the standard dose you could achieve that the standard dose you could achieve that through diet, right? You'd have to eat a through diet, right? You'd have to eat a through diet, right? You'd have to eat a fair amount of steak and salmon, but fair amount of steak and salmon, but fair amount of steak and salmon, but like it's certainly possible. So, like like it's certainly possible. So, like like it's certainly possible. So, like we know that it's very safe and like we we know that it's very safe and like we we know that it's very safe and like we know that it has very few side effects. know that it has very few side effects. know that it has very few side effects. So, if you're going to if you're So, if you're going to if you're So, if you're going to if you're thinking about um supplements, I often thinking about um supplements, I often thinking about um supplements, I often think of this idea of positive think of this idea of positive think of this idea of positive asymmetry. So, like where is their asymmetry. So, like where is their asymmetry. So, like where is their potential for benefit with very low potential for benefit with very low potential for benefit with very low downside other than the the the cost to downside other than the the the cost to downside other than the the the cost to your wallet? Um so in terms of dose your wallet? Um so in terms of dose your wallet? Um so in terms of dose actually some of the like the first actually some of the like the first actually some of the like the first study that looked at creatine in the study that looked at creatine in the study that looked at creatine in the setting of sleep deprivation was in setting of sleep deprivation was in setting of sleep deprivation was in rugby players and they looked at rugby rugby players and they looked at rugby rugby players and they looked at rugby specific skills after you know in the specific skills after you know in the specific skills after you know in the setting of sleep deprivation they setting of sleep deprivation they setting of sleep deprivation they compared caffeine and creatine and a compared caffeine and creatine and a compared caffeine and creatine and a standard dose of creatine 5 to 10 grams standard dose of creatine 5 to 10 grams standard dose of creatine 5 to 10 grams depending on body weight right so a depending on body weight right so a depending on body weight right so a smaller person would take five grams a smaller person would take five grams a smaller person would take five grams a larger person would take 10 grams or larger person would take 10 grams or larger person would take 10 grams or somewhere in between was enough to see somewhere in between was enough to see somewhere in between was enough to see to see benefit in some of the depression to see benefit in some of the depression to see benefit in some of the depression trials again they're using 5 to 10 trials again they're using 5 to 10 trials again they're using 5 to 10 grams. Um some of them using 5 g and grams. Um some of them using 5 g and grams. Um some of them using 5 g and seeing benefit in the like the the one seeing benefit in the like the the one seeing benefit in the like the the one most recent sleep deprivation trial most recent sleep deprivation trial most recent sleep deprivation trial which is the one that got a lot lot of which is the one that got a lot lot of which is the one that got a lot lot of press um where people were sort of kept press um where people were sort of kept press um where people were sort of kept awake for a night and then they were awake for a night and then they were awake for a night and then they were given they were given creatine and it given they were given creatine and it given they were given creatine and it show it showed that it helped maintain show it showed that it helped maintain show it showed that it helped maintain their cognitive function um in the their cognitive function um in the their cognitive function um in the setting of sleep deprivation. I think setting of sleep deprivation. I think setting of sleep deprivation. I think they were using.3 grams per kilo. So they were using.3 grams per kilo. So they were using.3 grams per kilo. So that's where somebody like me would take that's where somebody like me would take that's where somebody like me would take 30 grams um but you know somebody like 30 grams um but you know somebody like 30 grams um but you know somebody like you might take 20 grams. So, um that's you might take 20 grams. So, um that's you might take 20 grams. So, um that's where like this dose escalation is where like this dose escalation is where like this dose escalation is happening. Um in if you look at studies happening. Um in if you look at studies happening. Um in if you look at studies where where where you're looking at creatine levels in the you're looking at creatine levels in the you're looking at creatine levels in the brain, you you start to see significant brain, you you start to see significant brain, you you start to see significant increases in brain creatine at sort of increases in brain creatine at sort of increases in brain creatine at sort of like loading type doses. So that's that like loading type doses. So that's that like loading type doses. So that's that kind of like.3 grams per kilo uh per day kind of like.3 grams per kilo uh per day kind of like.3 grams per kilo uh per day for you know a week or more. Um so for you know a week or more. Um so for you know a week or more. Um so that's like you know 20 to 30 grams a that's like you know 20 to 30 grams a that's like you know 20 to 30 grams a day. However, some of the evidence of day. However, some of the evidence of day. However, some of the evidence of benefit in things that are related to benefit in things that are related to benefit in things that are related to brain function seem to happen at much brain function seem to happen at much brain function seem to happen at much lower levels. So, I'm not convinced that lower levels. So, I'm not convinced that lower levels. So, I'm not convinced that everybody needs to take 30 grams of everybody needs to take 30 grams of everybody needs to take 30 grams of creatine a day because I have evidence creatine a day because I have evidence creatine a day because I have evidence from other studies that actually maybe from other studies that actually maybe from other studies that actually maybe even at 5 grams people are starting to even at 5 grams people are starting to even at 5 grams people are starting to see benefit. Um, so the way I kind of see benefit. Um, so the way I kind of see benefit. Um, so the way I kind of approach it right now is the gen I would approach it right now is the gen I would approach it right now is the gen I would generally recommend 0.1 g per kilo. Um, generally recommend 0.1 g per kilo. Um, generally recommend 0.1 g per kilo. Um, so I take 10 grams every day. so I take 10 grams every day. so I take 10 grams every day. >> And then yes, if you're very stressed or >> And then yes, if you're very stressed or >> And then yes, if you're very stressed or sleepd deprived, maybe you you could you sleepd deprived, maybe you you could you sleepd deprived, maybe you you could you could try increasing the dose. So for could try increasing the dose. So for could try increasing the dose. So for me, as it is for some people, but not me, as it is for some people, but not me, as it is for some people, but not everybody, creatine is quite um everybody, creatine is quite um everybody, creatine is quite um alerting. Like it feels like a very very alerting. Like it feels like a very very alerting. Like it feels like a very very mild stimulant without making me mild stimulant without making me mild stimulant without making me jittery. Like I've had a bunch of of jittery. Like I've had a bunch of of jittery. Like I've had a bunch of of coffee. So I can't take creatine late in coffee. So I can't take creatine late in coffee. So I can't take creatine late in the day cuz I don't sleep as well. Um, the day cuz I don't sleep as well. Um, the day cuz I don't sleep as well. Um, but like if I haven't slept well, I but like if I haven't slept well, I but like if I haven't slept well, I might double my dose for the day. Um but might double my dose for the day. Um but might double my dose for the day. Um but that's not like a long-term thing. So I that's not like a long-term thing. So I that's not like a long-term thing. So I think the standard dose is actually think the standard dose is actually think the standard dose is actually where people will start to see some where people will start to see some where people will start to see some benefit. Um and then maybe in edge cases benefit. Um and then maybe in edge cases benefit. Um and then maybe in edge cases um and that I expect much more research um and that I expect much more research um and that I expect much more research in Alzheimer's disease and other things in Alzheimer's disease and other things in Alzheimer's disease and other things to come. Um then maybe you know higher to come. Um then maybe you know higher to come. Um then maybe you know higher doses will end up being better. doses will end up being better. doses will end up being better. >> I can't let you go without talking about >> I can't let you go without talking about >> I can't let you go without talking about sleep. sleep. sleep. >> Uhhuh. >> Uhhuh. >> Uhhuh. >> On some level we all know this already. >> On some level we all know this already. >> On some level we all know this already. It's like we need to be getting eight It's like we need to be getting eight It's like we need to be getting eight hours of sleep. We need to be practicing hours of sleep. We need to be practicing hours of sleep. We need to be practicing good sleep hygiene. good sleep hygiene. good sleep hygiene. >> Clearly, sleep is just absolutely >> Clearly, sleep is just absolutely >> Clearly, sleep is just absolutely foundational to brain health.

There's also you experienced already. There's also you experienced already. There's also you know sleep is also really important for know sleep is also really important for know sleep is also really important for emotional processing and other things emotional processing and other things emotional processing and other things like REM sleep in particular.

So, um, we through the lymphatic system. So, um, we through the lymphatic system. So, um, we know that people who don't sleep enough know that people who don't sleep enough know that people who don't sleep enough longterm have a have a higher risk of of longterm have a have a higher risk of of longterm have a have a higher risk of of dementia. The risk really seems to tick dementia. The risk really seems to tick dementia. The risk really seems to tick up in people who are chronically up in people who are chronically up in people who are chronically sleeping less than 6 hours a night. Um, sleeping less than 6 hours a night. Um, sleeping less than 6 hours a night. Um, which is probably lower than most people which is probably lower than most people which is probably lower than most people might expect. M might expect. M might expect. M >> um in general I think you so like people >> um in general I think you so like people >> um in general I think you so like people say 8 hours but in reality depending say 8 hours but in reality depending say 8 hours but in reality depending like person to person and it changes like person to person and it changes like person to person and it changes over time the window is more like 7 to n over time the window is more like 7 to n over time the window is more like 7 to n maybe even 6 to 10 hours like based on maybe even 6 to 10 hours like based on maybe even 6 to 10 hours like based on like how much sleep people need. So like like how much sleep people need. So like like how much sleep people need. So like you're waking up the next day you're you're waking up the next day you're you're waking up the next day you're feeling refreshed you feel good you're feeling refreshed you feel good you're feeling refreshed you feel good you're probably getting enough sleep regardless probably getting enough sleep regardless probably getting enough sleep regardless of what it was. Um things to consider of what it was. Um things to consider of what it was. Um things to consider how we think about our sleep is also is how we think about our sleep is also is how we think about our sleep is also is also is also really important. So people also is also really important. So people also is also really important. So people know you know the about the sleep know you know the about the sleep know you know the about the sleep routine like why sleep is important. Um routine like why sleep is important. Um routine like why sleep is important. Um the sort of like in addition to the the sort of like in addition to the the sort of like in addition to the sleep time uh sleep quality is critical. sleep time uh sleep quality is critical. sleep time uh sleep quality is critical. So usually when we think about poor So usually when we think about poor So usually when we think about poor sleep quality we know that's associated sleep quality we know that's associated sleep quality we know that's associated with increased risk of dementia. The way with increased risk of dementia. The way with increased risk of dementia. The way that we measure that is usually by that we measure that is usually by that we measure that is usually by asking people do you take something to asking people do you take something to asking people do you take something to help you sleep and those who take things help you sleep and those who take things help you sleep and those who take things to help them sleep tend to have a higher to help them sleep tend to have a higher to help them sleep tend to have a higher risk of dementia. That's probably risk of dementia. That's probably risk of dementia. That's probably because of a downstream effect of the because of a downstream effect of the because of a downstream effect of the things that they're taking. So are you things that they're taking. So are you things that they're taking. So are you drinking alcohol to get to get to sleep? drinking alcohol to get to get to sleep? drinking alcohol to get to get to sleep? Are you taking um antihistamines like Are you taking um antihistamines like Are you taking um antihistamines like benadryil to get to sleep? Are you benadryil to get to sleep? Are you benadryil to get to sleep? Are you taking things like ambient uh to get to taking things like ambient uh to get to taking things like ambient uh to get to sleep? There is probably a combination sleep? There is probably a combination sleep? There is probably a combination of um issues that are causing insomnia of um issues that are causing insomnia of um issues that are causing insomnia in the first place that haven't been in the first place that haven't been in the first place that haven't been dealt with plus the the the effect of dealt with plus the the the effect of dealt with plus the the the effect of those medications themselves. Um if we those medications themselves. Um if we those medications themselves. Um if we consider alcohol self- medication that consider alcohol self- medication that consider alcohol self- medication that negatively impact our sleep and that's negatively impact our sleep and that's negatively impact our sleep and that's probably why contributing to long-term probably why contributing to long-term probably why contributing to long-term increased dementia risk. So alcohol increased dementia risk. So alcohol increased dementia risk. So alcohol creates a REM sleep deficiency in creates a REM sleep deficiency in creates a REM sleep deficiency in general. Um if you're using alcohol to general. Um if you're using alcohol to general. Um if you're using alcohol to counteract all the caffeine that you counteract all the caffeine that you counteract all the caffeine that you drank during the day because you didn't drank during the day because you didn't drank during the day because you didn't sleep well the night before which is a sleep well the night before which is a sleep well the night before which is a very common sort of vicious cycle then very common sort of vicious cycle then very common sort of vicious cycle then uh caffeine can also impair deep sleep uh caffeine can also impair deep sleep uh caffeine can also impair deep sleep in particular. So if you're drinking in particular. So if you're drinking in particular. So if you're drinking still drinking caffeine in the afternoon still drinking caffeine in the afternoon still drinking caffeine in the afternoon then having a glass of wine to help you then having a glass of wine to help you then having a glass of wine to help you fall asleep right there sort of like a fall asleep right there sort of like a fall asleep right there sort of like a double whammy effect there. um ambience double whammy effect there. um ambience double whammy effect there. um ambience seems to negatively affect various seems to negatively affect various seems to negatively affect various aspects of neuroplasticity which um you aspects of neuroplasticity which um you aspects of neuroplasticity which um you can see this is mainly from animal can see this is mainly from animal can see this is mainly from animal studies um but uh then the studies um but uh then the studies um but uh then the antihistamines because they're antihistamines because they're antihistamines because they're anticolinergic and aylcoline which they anticolinergic and aylcoline which they anticolinergic and aylcoline which they sort of influence the function of is sort of influence the function of is sort of influence the function of is really important part of of long-term really important part of of long-term really important part of of long-term cognitive function those antihistamines cognitive function those antihistamines cognitive function those antihistamines that make you drowsy we know if you take that make you drowsy we know if you take that make you drowsy we know if you take those regularly that's associated with those regularly that's associated with those regularly that's associated with increased risk of dementia so thinking increased risk of dementia so thinking increased risk of dementia so thinking about are you using those things to go about are you using those things to go about are you using those things to go to sleep um if you require those things to sleep um if you require those things to sleep um if you require those things to go to sleep.

Um but equally people people who have insomnia people who have insomnia people who have insomnia the the required architecture to get the the required architecture to get the the required architecture to get good quality sleep is still there. It's good quality sleep is still there. It's good quality sleep is still there. It's just that the environment and the just that the environment and the just that the environment and the cognitive processes around sleep like cognitive processes around sleep like cognitive processes around sleep like they either don't feel safe or they're they either don't feel safe or they're they either don't feel safe or they're unable to wind down such that you can unable to wind down such that you can unable to wind down such that you can produce sleep. So that's where things produce sleep. So that's where things produce sleep. So that's where things like cognitive behavioral cognitive like cognitive behavioral cognitive like cognitive behavioral cognitive behavioral therapy for insomnia CBTI can behavioral therapy for insomnia CBTI can behavioral therapy for insomnia CBTI can become important. That's where the sleep become important. That's where the sleep become important. That's where the sleep environment can become important. Again environment can become important. Again environment can become important. Again we can become dependent on those we can become dependent on those we can become dependent on those medications. So you might need expert medications. So you might need expert medications. So you might need expert help to overcome that. But your sleep help to overcome that. But your sleep help to overcome that. But your sleep isn't broken. You just need to like isn't broken. You just need to like isn't broken. You just need to like retrain yourself up. The the final thing retrain yourself up. The the final thing retrain yourself up. The the final thing that's that I I think is is worth that's that I I think is is worth that's that I I think is is worth mentioning is that for many people, mentioning is that for many people, mentioning is that for many people, we've kind of swung too far in the other we've kind of swung too far in the other we've kind of swung too far in the other direction when it comes to sleep. Um and direction when it comes to sleep. Um and direction when it comes to sleep. Um and the sort of like the hyperfocus on the sort of like the hyperfocus on the sort of like the hyperfocus on wearable data. Um, and this idea of wearable data. Um, and this idea of wearable data. Um, and this idea of orthosomnia where we become so focused orthosomnia where we become so focused orthosomnia where we become so focused on wearable and like our our sleep on wearable and like our our sleep on wearable and like our our sleep metrics become the target whereas the metrics become the target whereas the metrics become the target whereas the target should be that you get a restful target should be that you get a restful target should be that you get a restful night of sleep because it allows you to night of sleep because it allows you to night of sleep because it allows you to do all these other amazing things. do all these other amazing things. do all these other amazing things. >> It's the new garment like oh if I if it >> It's the new garment like oh if I if it >> It's the new garment like oh if I if it if it's not tracked I didn't actually if it's not tracked I didn't actually if it's not tracked I didn't actually sleep last night or I wake up and I sleep last night or I wake up and I sleep last night or I wake up and I don't know what to do with myself. I don't know what to do with myself. I don't know what to do with myself. I mean I you know I have a Whoop. I love mean I you know I have a Whoop. I love mean I you know I have a Whoop. I love it. I definitely check it every morning, it. I definitely check it every morning, it. I definitely check it every morning, but I try to have an armslength uh but I try to have an armslength uh but I try to have an armslength uh relationship with how I let that data relationship with how I let that data relationship with how I let that data impact me. I still have to live my day impact me. I still have to live my day impact me. I still have to live my day and if it's all in the red, you know, and if it's all in the red, you know, and if it's all in the red, you know, like what is that doing to my mind in like what is that doing to my mind in like what is that doing to my mind in terms of how I'm appro problem solving terms of how I'm appro problem solving terms of how I'm appro problem solving and approaching those problems and and approaching those problems and and approaching those problems and making sure that I maintain a positive making sure that I maintain a positive making sure that I maintain a positive mindset? Would I be better off had I not mindset? Would I be better off had I not mindset? Would I be better off had I not known that I was in the red? You know, known that I was in the red? You know, known that I was in the red? You know, like with from an Ellen Langanger like with from an Ellen Langanger like with from an Ellen Langanger perspective if I like I feel great, you perspective if I like I feel great, you perspective if I like I feel great, you know, and I think I have a healthy know, and I think I have a healthy know, and I think I have a healthy relationship with that. But I can see relationship with that. But I can see relationship with that. But I can see how that becomes problematic for people how that becomes problematic for people how that becomes problematic for people and it becomes, you know, like a and it becomes, you know, like a and it becomes, you know, like a neurosis. neurosis. neurosis. >> You you know, there was one classic >> You you know, there was one classic >> You you know, there was one classic Ellen Langanger study, she wasn't the Ellen Langanger study, she wasn't the Ellen Langanger study, she wasn't the the senior author. The senior author was the senior author. The senior author was the senior author. The senior author was um Steven Lachley because he's a um Steven Lachley because he's a um Steven Lachley because he's a cicadian biologist at Harvard. But they cicadian biologist at Harvard. But they cicadian biologist at Harvard. But they collaborated on a study where they had collaborated on a study where they had collaborated on a study where they had people come into the lab and they were people come into the lab and they were people come into the lab and they were randomized to sleep either for 5 hours randomized to sleep either for 5 hours randomized to sleep either for 5 hours or 8 hours but in classic Ellen Langa or 8 hours but in classic Ellen Langa or 8 hours but in classic Ellen Langa style they manipulated clock time. style they manipulated clock time. style they manipulated clock time. Right? So they changed how long people Right? So they changed how long people Right? So they changed how long people thought they'd slept relative to how thought they'd slept relative to how thought they'd slept relative to how they actually slept. And what they found they actually slept. And what they found they actually slept. And what they found was that how long you thought you slept was that how long you thought you slept was that how long you thought you slept was a better predictor of how you felt was a better predictor of how you felt was a better predictor of how you felt the next and performed the next day than the next and performed the next day than the next and performed the next day than how you actually slept. So the example how you actually slept. So the example how you actually slept. So the example being people who slept for 5 hours but being people who slept for 5 hours but being people who slept for 5 hours but thought they had slept for for 8 hours thought they had slept for for 8 hours thought they had slept for for 8 hours didn't experience any impact on their didn't experience any impact on their didn't experience any impact on their function the next day. Uh and there are function the next day. Uh and there are function the next day. Uh and there are other studies that have used wearable other studies that have used wearable other studies that have used wearable data to manipulate this like hey you data to manipulate this like hey you data to manipulate this like hey you slept terribly last night even if they slept terribly last night even if they slept terribly last night even if they slept fine. slept fine. slept fine. >> How fatigued they feel the next day is >> How fatigued they feel the next day is >> How fatigued they feel the next day is based on how well they they think they based on how well they they think they based on how well they they think they slept. Um this is important because slept. Um this is important because slept. Um this is important because wearables aren't great at actually wearables aren't great at actually wearables aren't great at actually detecting the quality of your sleep. um detecting the quality of your sleep. um detecting the quality of your sleep. um they can tell you how long you're asleep they can tell you how long you're asleep they can tell you how long you're asleep for pretty well, but telling you whether for pretty well, but telling you whether for pretty well, but telling you whether you're in like deep sleep versus REM you're in like deep sleep versus REM you're in like deep sleep versus REM sleep, they're really not that good at sleep, they're really not that good at sleep, they're really not that good at that. And this is like published data that. And this is like published data that. And this is like published data that that are out there. So, when they that that are out there. So, when they that that are out there. So, when they use those sleep stages to tell you use those sleep stages to tell you use those sleep stages to tell you something about your recovery score or something about your recovery score or something about your recovery score or your sleep score the next morning, your sleep score the next morning, your sleep score the next morning, you're using quite low quality data to you're using quite low quality data to you're using quite low quality data to tell you how you should feel that day. tell you how you should feel that day. tell you how you should feel that day. So, the way that I've used this with So, the way that I've used this with So, the way that I've used this with professional athletes, um, and they're professional athletes, um, and they're professional athletes, um, and they're lucky because I work, you know, with lucky because I work, you know, with lucky because I work, you know, with their coaches who can sort of who sort their coaches who can sort of who sort their coaches who can sort of who sort of like oversee this stuff on a of like oversee this stuff on a of like oversee this stuff on a day-to-day basis, I would usually have day-to-day basis, I would usually have day-to-day basis, I would usually have the athlete, the athlete doesn't see the the athlete, the athlete doesn't see the the athlete, the athlete doesn't see the data, but the coach sees the data and data, but the coach sees the data and data, but the coach sees the data and they use that to look at trends over they use that to look at trends over they use that to look at trends over time, which are probably more accurate time, which are probably more accurate time, which are probably more accurate than like individual pieces of data. Um, than like individual pieces of data. Um, than like individual pieces of data. Um, so then we can integrate it and kind of so then we can integrate it and kind of so then we can integrate it and kind of change change change >> um, uh, kind of change things if if we >> um, uh, kind of change things if if we >> um, uh, kind of change things if if we need to. if you can create right I think need to. if you can create right I think need to. if you can create right I think you create like a a cognitive distance you create like a a cognitive distance you create like a a cognitive distance from the data but like I think you can from the data but like I think you can from the data but like I think you can also create a temporal distance from the also create a temporal distance from the also create a temporal distance from the data because like you don't need to know data because like you don't need to know data because like you don't need to know how you slept last night in order to be how you slept last night in order to be how you slept last night in order to be able to perform today because you have able to perform today because you have able to perform today because you have to perform today regardless or you have to perform today regardless or you have to perform today regardless or you have to go about your day regardless to go about your day regardless to go about your day regardless >> review like a week later go back and >> review like a week later go back and >> review like a week later go back and review the past week review the past week review the past week >> yeah especially if you can then say oh >> yeah especially if you can then say oh >> yeah especially if you can then say oh yeah I didn't sleep that well that night yeah I didn't sleep that well that night yeah I didn't sleep that well that night but that was the night where I went to but that was the night where I went to but that was the night where I went to bed late or that was the night where I bed late or that was the night where I bed late or that was the night where I had an extra beer before bed or that was had an extra beer before bed or that was had an extra beer before bed or that was the night where I had a coffee in the the night where I had a coffee in the the night where I had a coffee in the afternoon right so you can still use afternoon right so you can still use afternoon right so you can still use those data to inform important things, those data to inform important things, those data to inform important things, but you're not allowing it to influence but you're not allowing it to influence but you're not allowing it to influence how you then, you know, perform on a on how you then, you know, perform on a on how you then, you know, perform on a on a daily basis. a daily basis. a daily basis. >> Speaking of the relationship between the >> Speaking of the relationship between the >> Speaking of the relationship between the rest itself and your kind of mental rest itself and your kind of mental rest itself and your kind of mental relationship with the rest, uh this is relationship with the rest, uh this is relationship with the rest, uh this is something that is kind of an important something that is kind of an important something that is kind of an important issue in the world of Formula 1 and issue in the world of Formula 1 and issue in the world of Formula 1 and you've, you know, played a role in you've, you know, played a role in you've, you know, played a role in working with some of those athletes working with some of those athletes working with some of those athletes because they're just literally going because they're just literally going because they're just literally going >> across the world every week. I mean, the >> across the world every week. I mean, the >> across the world every week. I mean, the time zone shifts are insane. Yeah. time zone shifts are insane. Yeah. time zone shifts are insane. Yeah. >> So, what have you learned about working >> So, what have you learned about working >> So, what have you learned about working with those athletes and how have you with those athletes and how have you with those athletes and how have you counseledled them? counseledled them? counseledled them? >> Some things that I've learned, um, which >> Some things that I've learned, um, which >> Some things that I've learned, um, which were surprising to me at the time, but were surprising to me at the time, but were surprising to me at the time, but maybe shouldn't have been, is that the maybe shouldn't have been, is that the maybe shouldn't have been, is that the basics, particularly when it comes to basics, particularly when it comes to basics, particularly when it comes to rest and recovery, the basics still rest and recovery, the basics still rest and recovery, the basics still matter. So, I've had matter. So, I've had matter. So, I've had um athletes come to me and say, "Oh, I'm um athletes come to me and say, "Oh, I'm um athletes come to me and say, "Oh, I'm looking at my wearable data. I'm worried looking at my wearable data. I'm worried looking at my wearable data. I'm worried I'm not getting enough REM sleep as a as I'm not getting enough REM sleep as a as I'm not getting enough REM sleep as a as a as an example. And I look through the a as an example. And I look through the a as an example. And I look through the data and it's very clear why they're data and it's very clear why they're data and it's very clear why they're spending 5 hours in bed. If you f spend spending 5 hours in bed. If you f spend spending 5 hours in bed. If you f spend 5 hours in bed, we know that most of 5 hours in bed, we know that most of 5 hours in bed, we know that most of your REM sleep happens at the end of the your REM sleep happens at the end of the your REM sleep happens at the end of the night. You're you're going to get less night. You're you're going to get less night. You're you're going to get less REM sleep. First of all, is that REM REM sleep. First of all, is that REM REM sleep. First of all, is that REM sleep number that accurate? Hard to sleep number that accurate? Hard to sleep number that accurate? Hard to tell. Um but second of all, um like the tell. Um but second of all, um like the tell. Um but second of all, um like the the the most important thing for getting the the most important thing for getting the the most important thing for getting a good quality night of sleep is getting a good quality night of sleep is getting a good quality night of sleep is getting enough sleep opportunity, which just enough sleep opportunity, which just enough sleep opportunity, which just means spending enough time in bed ready means spending enough time in bed ready means spending enough time in bed ready to ready to sleep. And you see this to ready to sleep. And you see this to ready to sleep. And you see this again and again, like when there's again and again, like when there's again and again, like when there's issues with sleep, it's that athletes issues with sleep, it's that athletes issues with sleep, it's that athletes athletes aren't giving themselves the athletes aren't giving themselves the athletes aren't giving themselves the time and opportunity to get high quality time and opportunity to get high quality time and opportunity to get high quality rest. Of course, some of that comes from rest. Of course, some of that comes from rest. Of course, some of that comes from a travel schedule and things like that. a travel schedule and things like that. a travel schedule and things like that. So, you kind of have to take that into So, you kind of have to take that into So, you kind of have to take that into account. Um, but when they are able to account. Um, but when they are able to account. Um, but when they are able to build those routines or maintain those build those routines or maintain those build those routines or maintain those routines or maintain the things that routines or maintain the things that routines or maintain the things that help support sleep at home whilst help support sleep at home whilst help support sleep at home whilst they're traveling, they can maintain a they're traveling, they can maintain a they're traveling, they can maintain a much better um quality of of sleep. much better um quality of of sleep. much better um quality of of sleep. something that we do. So the I do all my something that we do. So the I do all my something that we do. So the I do all my Formula One work through a company Formula One work through a company Formula One work through a company called Hints of Performance. Um and called Hints of Performance. Um and called Hints of Performance. Um and they, you know, so we work with the co they, you know, so we work with the co they, you know, so we work with the co with the coaches as as well.

So can we start to have them shift their circadian rhythm before shift their circadian rhythm before shift their circadian rhythm before before they travel? So, it's starting to before they travel? So, it's starting to before they travel? So, it's starting to manipulate caffeine and light and sleep manipulate caffeine and light and sleep manipulate caffeine and light and sleep time and food timing um a day or two time and food timing um a day or two time and food timing um a day or two before they travel um you know so that before they travel um you know so that before they travel um you know so that they're closer to the the target time uh they're closer to the the target time uh they're closer to the the target time uh when they get there. And there are a when they get there. And there are a when they get there. And there are a number of apps that kind of allow you to number of apps that kind of allow you to number of apps that kind of allow you to to do that. Now, there's one called Faze to do that. Now, there's one called Faze to do that. Now, there's one called Faze that was developed by one of these F1 that was developed by one of these F1 that was developed by one of these F1 coaches uh because he was so used to coaches uh because he was so used to coaches uh because he was so used to having to do this on a daily basis, he's having to do this on a daily basis, he's having to do this on a daily basis, he's now kind of um created something that now kind of um created something that now kind of um created something that that people can use themselves. But then that people can use themselves. But then that people can use themselves.

And like on a sleep perspective, at least from that study, perspective, at least from that study, perspective, at least from that study, it kind of suggests no, it's not. And we it kind of suggests no, it's not. And we it kind of suggests no, it's not. And we see that then across all of these see that then across all of these see that then across all of these different um areas. So there are now different um areas. So there are now different um areas. So there are now multiple studies where um you know the multiple studies where um you know the multiple studies where um you know the the best evidence probably comes from the best evidence probably comes from the best evidence probably comes from multi- um like multi-intervention multi- um like multi-intervention multi- um like multi-intervention um kind of approaches. So um the the um kind of approaches. So um the the um kind of approaches. So um the the most famous one is finger was run in most famous one is finger was run in most famous one is finger was run in Finland. It was just repeated here in Finland. It was just repeated here in Finland. It was just repeated here in the US was uh that study was called the US was uh that study was called the US was uh that study was called pointer. Um lots of other studies have pointer. Um lots of other studies have pointer. Um lots of other studies have um around the world have done something um around the world have done something um around the world have done something essentially similar. But what they do is essentially similar. But what they do is essentially similar. But what they do is they address cardiovascular risk. They they address cardiovascular risk. They they address cardiovascular risk. They have people start a new exercise have people start a new exercise have people start a new exercise training program with some resistance training program with some resistance training program with some resistance and aerobic exercise. They have them uh and aerobic exercise. They have them uh and aerobic exercise. They have them uh improve their improve their diet improve their improve their diet improve their improve their diet quality. And then you know there's quality. And then you know there's quality. And then you know there's there's some other some other pieces. there's some other some other pieces. there's some other some other pieces. Sometimes there's like a a stress Sometimes there's like a a stress Sometimes there's like a a stress reduction component. Um but like just reduction component. Um but like just reduction component. Um but like just starting to attend to some of these starting to attend to some of these starting to attend to some of these basics and this is either in people at basics and this is either in people at basics and this is either in people at high risk of dementia or starting to high risk of dementia or starting to high risk of dementia or starting to experience some decline already. And experience some decline already. And experience some decline already. And actually you see bigger benefits you actually you see bigger benefits you actually you see bigger benefits you tend to see bigger benefits in people tend to see bigger benefits in people tend to see bigger benefits in people who've maybe you know starting to see who've maybe you know starting to see who've maybe you know starting to see some decline. Not that they've gotten a some decline. Not that they've gotten a some decline. Not that they've gotten a diagnosis of dementia but you know maybe diagnosis of dementia but you know maybe diagnosis of dementia but you know maybe they're already below the below kind of they're already below the below kind of they're already below the below kind of the average in terms of cognitive the average in terms of cognitive the average in terms of cognitive function. And you can see this within function. And you can see this within function. And you can see this within sort of like six to six to 12 months of sort of like six to six to 12 months of sort of like six to six to 12 months of just starting to attend some of these just starting to attend some of these just starting to attend some of these basics. once you're already in your 60s basics. once you're already in your 60s basics. once you're already in your 60s and 70s. So if you start even earlier, and 70s. So if you start even earlier, and 70s. So if you start even earlier, right, you start in your 30s, 40s, 50s, right, you start in your 30s, 40s, 50s, right, you start in your 30s, 40s, 50s, you potentially have 20 years to change you potentially have 20 years to change you potentially have 20 years to change this trajectory. Another example might this trajectory. Another example might this trajectory. Another example might be when you look at cognitive changes be when you look at cognitive changes be when you look at cognitive changes that happen during um permenopause, the that happen during um permenopause, the that happen during um permenopause, the menopausal transition in women, which is menopausal transition in women, which is menopausal transition in women, which is in that kind of towards the you know mid in that kind of towards the you know mid in that kind of towards the you know mid to latter part of that that uh time to latter part of that that uh time to latter part of that that uh time window that you mentioned. we see that window that you mentioned. we see that window that you mentioned. we see that greater cognitive changes um tend to be greater cognitive changes um tend to be greater cognitive changes um tend to be experienced in those who have some experienced in those who have some experienced in those who have some element of say metabolic disease. Um so element of say metabolic disease. Um so element of say metabolic disease. Um so the what the Swan study in in the US the what the Swan study in in the US the what the Swan study in in the US showed that. Um so again we know that um showed that. Um so again we know that um showed that. Um so again we know that um changing your diet, changing your changing your diet, changing your changing your diet, changing your physical activity, um addressing physical activity, um addressing physical activity, um addressing cardiovascular risk factors then affect cardiovascular risk factors then affect cardiovascular risk factors then affect um your uh the severity of metabolic um your uh the severity of metabolic um your uh the severity of metabolic syndrome and related components that you syndrome and related components that you syndrome and related components that you can you can improve blood pressure, you can you can improve blood pressure, you can you can improve blood pressure, you can improve blood sugar and you know can improve blood sugar and you know can improve blood sugar and you know doing that at that time period could doing that at that time period could doing that at that time period could potentially like completely change that potentially like completely change that potentially like completely change that that trajectory. So all of that to say that trajectory. So all of that to say that trajectory. So all of that to say like wherever you are in that window um like wherever you are in that window um like wherever you are in that window um even if you're beyond that 55 years old even if you're beyond that 55 years old even if you're beyond that 55 years old there's still scope to change that there's still scope to change that there's still scope to change that trajectory trajectory trajectory >> that is incredibly empowering and and >> that is incredibly empowering and and >> that is incredibly empowering and and speaks to the unbelievable resilience of speaks to the unbelievable resilience of speaks to the unbelievable resilience of the human being. Yeah. Like it's it is the human being. Yeah. Like it's it is the human being. Yeah. Like it's it is kind of amazing. But reflecting on how kind of amazing. But reflecting on how kind of amazing. But reflecting on how we kind of opened this podcast with this we kind of opened this podcast with this we kind of opened this podcast with this notion that 45 and you say up to 70% of notion that 45 and you say up to 70% of notion that 45 and you say up to 70% of dementia cases are preventable and here dementia cases are preventable and here dementia cases are preventable and here we are talking about you know people who we are talking about you know people who we are talking about you know people who are kind of tiptoeing into that and are kind of tiptoeing into that and are kind of tiptoeing into that and there's still the opportunity to halt it there's still the opportunity to halt it there's still the opportunity to halt it reverse some of the symptomology or like reverse some of the symptomology or like reverse some of the symptomology or like stave off you know this this this you stave off you know this this this you stave off you know this this this you know kind of terrible future. Why isn't know kind of terrible future. Why isn't know kind of terrible future. Why isn't this something that everyone is shouting this something that everyone is shouting this something that everyone is shouting from the mountain tops? Like so many from the mountain tops? Like so many from the mountain tops? Like so many people are suffering from this just people are suffering from this just people are suffering from this just absolute horrible affliction that is absolute horrible affliction that is absolute horrible affliction that is devastating to families. Like I feel devastating to families. Like I feel devastating to families. Like I feel like this is a message that needs to get like this is a message that needs to get like this is a message that needs to get out there and should be being repeated out there and should be being repeated out there and should be being repeated constantly. You know, you can avoid constantly. You know, you can avoid constantly. You know, you can avoid this. this. this. >> Here's the way to do this. Why is this >> Here's the way to do this. Why is this >> Here's the way to do this. Why is this the conversation that we're not having the conversation that we're not having the conversation that we're not having all the time? I'll I'll like before I all the time? I'll I'll like before I all the time? I'll I'll like before I get into that I'll quickly say that that get into that I'll quickly say that that get into that I'll quickly say that that 70% number wasn't something that I made 70% number wasn't something that I made 70% number wasn't something that I made up. That was another analysis that was up. That was another analysis that was up. That was another analysis that was done by professor Jayu using UK bio bank done by professor Jayu using UK bio bank done by professor Jayu using UK bio bank data. So a big data set of more than data. So a big data set of more than data. So a big data set of more than half a million people in the UK they half a million people in the UK they half a million people in the UK they estimated the upper end of of dementias estimated the upper end of of dementias estimated the upper end of of dementias that may be preventable is is over 70%. that may be preventable is is over 70%. that may be preventable is is over 70%. So again just like a similar way you do So again just like a similar way you do So again just like a similar way you do a big statistical analysis and that's a big statistical analysis and that's a big statistical analysis and that's the kind of number that comes out. So the kind of number that comes out. So the kind of number that comes out. So like regardless of where the truth is in like regardless of where the truth is in like regardless of where the truth is in that in that range um whatever it ends that in that range um whatever it ends that in that range um whatever it ends up being right there that's still a huge up being right there that's still a huge up being right there that's still a huge number of dementias that are potentially number of dementias that are potentially number of dementias that are potentially preventable. Of course we're talking at preventable. Of course we're talking at preventable. Of course we're talking at the population level right we can't and the population level right we can't and the population level right we can't and we're talking about statistics and we're talking about statistics and we're talking about statistics and probabilities. I'm not saying that you probabilities. I'm not saying that you probabilities. I'm not saying that you could definitely pre prevent any could definitely pre prevent any could definitely pre prevent any individual person from from getting individual person from from getting individual person from from getting dementia but we know we can dramatically dementia but we know we can dramatically dementia but we know we can dramatically decrease our risk. So I'm I'm really decrease our risk. So I'm I'm really decrease our risk. So I'm I'm really hopeful that the conversation is hopeful that the conversation is hopeful that the conversation is changing like over the last two or three changing like over the last two or three changing like over the last two or three years in particular like especially um a years in particular like especially um a years in particular like especially um a lot of people struggled uh with their lot of people struggled uh with their lot of people struggled uh with their brains after COVID either due to you brains after COVID either due to you brains after COVID either due to you know long COVID or the effects of you know long COVID or the effects of you know long COVID or the effects of you know lockdown and everything how that know lockdown and everything how that know lockdown and everything how that changed you know the the sort of like changed you know the the sort of like changed you know the the sort of like our lifestyle and on our environment and our lifestyle and on our environment and our lifestyle and on our environment and since you know the since the last sort since you know the since the last sort since you know the since the last sort of two or three years people have been of two or three years people have been of two or three years people have been talking about brain health more and more talking about brain health more and more talking about brain health more and more and more and so I see it out there, you and more and so I see it out there, you and more and so I see it out there, you know, they're mentioning uh Jill know, they're mentioning uh Jill know, they're mentioning uh Jill Livingston's work and they're mentioning Livingston's work and they're mentioning Livingston's work and they're mentioning some of these analyses and they're some of these analyses and they're some of these analyses and they're saying that, you know, it's not too saying that, you know, it's not too saying that, you know, it's not too late, you know, things like the pointer late, you know, things like the pointer late, you know, things like the pointer trial that was just published last year. trial that was just published last year. trial that was just published last year. So, I agree that we're not saying it So, I agree that we're not saying it So, I agree that we're not saying it enough. Um, and I agree that we should enough. Um, and I agree that we should enough. Um, and I agree that we should be hopeful if we're able to engage at be hopeful if we're able to engage at be hopeful if we're able to engage at this on a personal level and then this on a personal level and then this on a personal level and then ideally make changes at a societal level ideally make changes at a societal level ideally make changes at a societal level as well. Um, but I think that tide is as well. Um, but I think that tide is as well. Um, but I think that tide is changing. So, I hope that um you know, changing. So, I hope that um you know, changing. So, I hope that um you know, you and I speak in a year or two and you you and I speak in a year or two and you you and I speak in a year or two and you can be like, "Oh, yeah, you're right." can be like, "Oh, yeah, you're right." can be like, "Oh, yeah, you're right." You know, people are talking about this You know, people are talking about this You know, people are talking about this more and more and people are realizing more and more and people are realizing more and more and people are realizing they have so much more agency here. Um they have so much more agency here. Um they have so much more agency here. Um and so I hope it's going that direction and so I hope it's going that direction and so I hope it's going that direction and it certainly seems like people are and it certainly seems like people are and it certainly seems like people are starting to go that way. starting to go that way. starting to go that way. >> That's very exciting. >> That's very exciting. >> That's very exciting. >> Yeah. >> Yeah. >> Yeah. >> So maybe to conclude uh the >> So maybe to conclude uh the >> So maybe to conclude uh the conversation, it would be good if you conversation, it would be good if you conversation, it would be good if you could, you know, even like look right to could, you know, even like look right to could, you know, even like look right to camera is like what do you want people camera is like what do you want people camera is like what do you want people to know? like there somebody's listening to know? like there somebody's listening to know? like there somebody's listening to this. I've never heard anything like to this. I've never heard anything like to this. I've never heard anything like this before. Oh my goodness. You know, I this before. Oh my goodness. You know, I this before. Oh my goodness. You know, I now am going to take greater uh agency now am going to take greater uh agency now am going to take greater uh agency over these decisions that I'm going to over these decisions that I'm going to over these decisions that I'm going to make. I certainly don't want to have make. I certainly don't want to have make. I certainly don't want to have this kind of thing happen to me. How do this kind of thing happen to me. How do this kind of thing happen to me. How do I begin and how can you kind of leave I begin and how can you kind of leave I begin and how can you kind of leave them with an empowering message about them with an empowering message about them with an empowering message about how to embark upon this journey? how to embark upon this journey? how to embark upon this journey? >> Sure. So, the thing that I want >> Sure. So, the thing that I want >> Sure. So, the thing that I want everybody to know is that we each have a everybody to know is that we each have a everybody to know is that we each have a huge amount of control over our huge amount of control over our huge amount of control over our long-term cog uh cognitive trajectory long-term cog uh cognitive trajectory long-term cog uh cognitive trajectory and we can dramatically decrease our and we can dramatically decrease our and we can dramatically decrease our risk of dementia even if we have uh a risk of dementia even if we have uh a risk of dementia even if we have uh a family history of dementia or you know family history of dementia or you know family history of dementia or you know um no people with dementia. And the best um no people with dementia. And the best um no people with dementia. And the best way to start to do this is just to find way to start to do this is just to find way to start to do this is just to find one thing that you know you can start to one thing that you know you can start to one thing that you know you can start to move the needle on that feels um uh move the needle on that feels um uh move the needle on that feels um uh doable to you. And so it could be slight doable to you. And so it could be slight doable to you. And so it could be slight changes to your diet. It could be um changes to your diet. It could be um changes to your diet. It could be um adding a new aspect to your exercise adding a new aspect to your exercise adding a new aspect to your exercise routine. Uh it could be going to your routine. Uh it could be going to your routine. Uh it could be going to your doctor and getting your blood pressure doctor and getting your blood pressure doctor and getting your blood pressure checked and treating it if you need to. checked and treating it if you need to. checked and treating it if you need to. Um think about uh the risk factors for Um think about uh the risk factors for Um think about uh the risk factors for other people that you know or in your other people that you know or in your other people that you know or in your family who had dementia that you might family who had dementia that you might family who had dementia that you might share with them. That's always a great share with them. That's always a great share with them. That's always a great place to start, too. And know that place to start, too. And know that place to start, too. And know that because because because all the different um factors that affect all the different um factors that affect all the different um factors that affect brain health interact with one another, brain health interact with one another, brain health interact with one another, when you start to change one thing, the when you start to change one thing, the when you start to change one thing, the whole network will start to shift in whole network will start to shift in whole network will start to shift in your favor. your favor. your favor. >> Amen. I love it. Uh to the audience, uh >> Amen. I love it. Uh to the audience, uh >> Amen. I love it. Uh to the audience, uh I want to say we covered a lot of ground I want to say we covered a lot of ground I want to say we covered a lot of ground today. Uh and it may feel like, hey, we today. Uh and it may feel like, hey, we today. Uh and it may feel like, hey, we didn't drill down enough on this, that, didn't drill down enough on this, that, didn't drill down enough on this, that, or the other thing. Well, the good news or the other thing. Well, the good news or the other thing. Well, the good news is uh you can find all the particulars is uh you can find all the particulars is uh you can find all the particulars in Tommy's new book, The Stimulated in Tommy's new book, The Stimulated in Tommy's new book, The Stimulated Mind, out now. Again, I'll say what I Mind, out now. Again, I'll say what I Mind, out now. Again, I'll say what I said at the outset, like this is a real said at the outset, like this is a real said at the outset, like this is a real public service, and your work is vital. public service, and your work is vital. public service, and your work is vital. Um, brain health obviously impacts all Um, brain health obviously impacts all Um, brain health obviously impacts all of us. Very few people are untouched by of us. Very few people are untouched by of us. Very few people are untouched by the diseases of cognitive decline. And the diseases of cognitive decline. And the diseases of cognitive decline. And so I urgently uh uh impress upon so I urgently uh uh impress upon so I urgently uh uh impress upon everybody who's watching and listening everybody who's watching and listening everybody who's watching and listening to pick up the book and um take your to pick up the book and um take your to pick up the book and um take your brain health more seriously. So thank brain health more seriously. So thank brain health more seriously. So thank you for your time today. you for your time today. you for your time today. >> Thanks so much for having me and I hope >> Thanks so much for having me and I hope >> Thanks so much for having me and I hope everybody found this useful. everybody found this useful. everybody found this useful. >> Peace. >> Peace. >> Peace. Cool.
