ah, blue sometimes a seed is all you need to allowed big ideas to grow. we're bringing environmental conservation to life with learning pass like global ideas. we will show you how climate change and environmental conservation is taking shape around the world and how we can all make a difference. knowledge grows through sharing, download it now for free. as you can that i want that tags and in the end the some me you are not allowed to see you anymore. we will send you back. are you familiar with this
reliance ivy? what's your story. ready he wasn't, i was women, especially victims of vine and seen a lot of them take part and send us your story. we are trying always to understand this new culture. so you are not a visitor, not the guests. you want to become a citizen. info migrants your platform for reliable information. mm hm. ah, what is aging? is it possible for us to affect it? how much more can we do? these are big questions. they're going to take us to answers that are going to be
illuminating to mankind as a whole. agent has become a hot topic. we are right now at the point where we can already develop strategies with injections, simulation stimulation methods, personal programs, pills course. we're in the midst of a seismic shift that will open up possibilities for more healthy agent and talk to with a something in the air, and we can feed it. and plenty of people who already show you gold nuggets and i'd say they ask gold here. you know right now where it seeing a huge gold rush. once the proof of concept is established on longevity, it will go viral. with was your name and date left there. so the person will live to 150. has probably already been born to die. it's highly likely that it is with
got about earlier. i wake up early just because it's important for my house to do this. so i do it. that's really going to be consistent in your sleep schedule. it's easy for me to be consistent with waking up at 5, the sort of nice, quiet time and yeah, i mean it's, it's, it's, so i do, it's that and have consistency because that's really important. think future katie or them? nina cara 1st became interested in longevity, research when she was 12. now the teenager is one of the scenes rising stars. nina stands for a generation that takes a new view of aging that wants to see aging eradicated
when she's not in school. nino holds talks around the world. she's launched a small start up with a couple of friends. the groups searches for scientific clues on how to crack the aging code. yeah. yeah, and one of our proteins is probably involved in that process in some way. so we could weigh how much that protein is involved in that process and try to give an estimate even if we're not adding a whole new protein involved with that process. yeah, i think that definitely something that we could that's useful to measure my grandfather did have it for me to my chest. that was the big problem and i wanted seasoning with that one in 6 women and get dementia after the 65. and i'm one in 10 man which is a lot of people when you think about it, right? it's these diseases that you previously thought were inevitable. so we thought maybe we'd have drugs to alleviate the pain or to sub one particular type of
disease from occurring. but never sort of to, you know, look at the root cause of these diseases and haggard from there. each animal species has in certain ways. and the expiration date in a mouse, it's less than 5 years in the bo had whale. it's 211 years in humans. it's a $120.00 to each species has a time that's kind of allocated to it. and the question is, why is that in nature? death is a normal part of life. but can we humans push this biological age limit? human life expectancy has risen steadily and recent history. back in ancient rome, it was to 25 years. by the middle ages, it was still only $35.00. now we live in to our seventy's on average medical advances and better living conditions are enabling us to get older and older. but
can we extend our lifespan indefinitely? and would we really want to as even believe vision, to live lots of people want to live forever. and when they wonder if we can reverse or slow down the aging process and unkind in existence tells us so much about violence which steph and dying. but it also touches on reincarnation and live live. it's a hugely popular fema me. immortality is a topic that will never die is or stablish in germany. there's a famous painting,
the fountain of youth. and on the painting you see all the old men and women, particularly taking their clothes off and getting into the fountain of youth and swimming across to the other side and emerging young and healthy on the other side . then going off to the tents and dressing and then having a wonderful dinner together with plenty of wine. ah, and it's, it's man's age old dream to be able to reverse aging his room. wouldn't it? this fountain of youth is become an allegory in biomedical research and that's no longer just about eating a healthy diet and leading a balance lifestyle. and we want to make more serious adjustments if you and we can take pills or get injections and so on. and we'll end up living longer when you come into the idea, the fountain of youth that's outside me and i'm end of that. i can jump into as it is shifted to a fountain that's put inside the 1000001 injected into my anger plan. i know i'm a buster we're closer to finding the fountain of youth than ever before.
but what if aging were kind of program a program we could hack into an initial clue as to how humans might be reprogrammed, leads to an unassuming setting in central america. ah, i've lived in costa rica since 1972 and just completely fell in love with costa rica and then to love. and acoya is a place where people age very well and long. i think about it all the time. i think about it all the time because it's really mysterious and they themselves cannot give you any clue as to why you ask them. and they say,
i have no idea. it just is what it is. but yet we are more curious and we want to know more on a gale, glenn takes care of some of the regions, centenarians, the residence of costa rica, nick jolla peninsula, not only live longer, but stay healthy for longer to almost die. i will hang on to my legs. don't get an oil navy. the koto is 90. 1 people here often live to be over 90. many thing to over a 100 dana florida. ask if i can go are you there? these are herbs who used to heal disease around corner. thus he had a bizarre. that's right. you want your hampton and lots of people around the world,
want to know how to live a long and healthy life. what's your advice? physical, if you have a combined i live with for many years. ha, guam, bad time. eat a healthy diet out of that hour and leave a peaceful stress free lie to you, or it will exit as well, or lots of vitamin these. no ha, ha, gas, she's laughing when a person, it's lots of cheese, their heart won't suffer nor i, it is gonna vote this area was very, very distantly removed from the mainland, so to speak. it's a peninsula, it's still connected, but our roads were bad. communication didn't exist, people survived here on what they planted on, what their parents taught them, how to survive. there was no pharmacy to go to that smell. so good
luck when the this her treats fever and all kinds of things or in the fact that people in nagoya live to be older than average went largely unnoticed until one scientist stumbled on to some unusual data. some years ago, we fought most young professional initiative. i was initially an economist, but it never really felt like to wait field for me. eventually i found my knees and demographics to much more precise. with clear cut rules. it's black and white, whole eat. and they got them anita castilla, not by sheer coincidence. we discovered that mortality rates in the region were much lower than the rest of the country in which importance held initially. i didn't pay much attention to. hello, my name is martha. i'll knock on when i presented my findings at a conference,
and there was a lot of skepticism. we asked about whether it was really so public and costa rica element that less causality been on a persona. but one person from the audience approach me afterwards and said, lucy, it's because it's a blue zone. you cannot get him when mom. and at that moment, i realized that nicola really was a special place, is un no korean nicole. yeah. fike, so called blue zones, had been identified so far on our planet. these are locations where an unusually high percentage of the population lives very long. men in natoya have the world's highest life expectancy. an 80 year old male here is likely to outlive his contemporaries elsewhere by an average 8.2 years ago. but why
this is our lovek? is it the diet rich and fruit in acoya high or does religious faith explain it? la federally? she ought. there wasn't any real data. john said that they're not meant and off. yeah, that's my daughter mama. my mother in law company. the question is, is, is it genetics or is it lifestyle and young people in costa rica say put of either good. i mean they can, you're still in the ok. see most of it campus. we carried out a study to see what happens when people lead nagoya to have. yeah. you know, and what happens when people from other parts of the country it moved to nagoya as part of the price of eating the core. yeah. the most. okay. we found out that neither of these groups achieved the same one, jabber to me, that is those who are born in spend their whole lives here in our navy on our tim
in blue zones, eating seems to proceed more slowly. a comfy huh. the environment and the lifestyle appear to positively impact human biology. but for matthew, but how exactly and will this help us crack the aging code? and the molecular biologist by akins, i'm interested in understanding the origin of diseases. the majority of diseases are those associated with the agent grosses. so i'm interested in understanding why we h o m molecular liver. i wanted to have all my life to on this found the origins of concern as united i felt illness could be the keep. the human
body consists of around 37 trillion cells, some last a few days. others lived for years. we constantly produce new cells to replace the old ones. it's a process that involves duplication. before cell division can take place the chromosomes in the cell, nicholas have to be duplicated the dna double helix. they consist of is unwind and separated into strands. each strand then becomes a template for any one. the ends of the chromosomes, which are especially prone to replication errors, are protected by telomeres, which are sequences of non coding dna. but with every cell division, these safety caps become shorter
charged. i feel charged with the shoe. all that ti long. ah, imagine this so shoe lace is our chromosome. so the spark of issue lays is the dna where the genetic information is on this little plastic bart, which is very important to protect the shoe lace, would be the tiller. so the d lamerse are very important to protect our chromosomes, to protect the, the inane, as we ates. the domains become shorter and shorter is because every time that we have a damage, the cells have to multiply over janae. the damage on these shortens the dilemma.
the cell division, this implication, so at the end the dilemma become so short by we don't have any more, a t t m. so now our dnas unprotected and this is leading to asia as leading to the c's. ultimately, we'll be leaving this cell division and the rate of telomeres shortening may be influenced by our lifestyle, smoking, stress, environmental pollutants, and poor nutrition are all negative factors. some researchers believe living in harmony with the natural world has a positive effect. no sought to ross, i can't, we couldn't carry out experiments like this in costa rica and i mean, so we sent her samples away and thought, when the results of this collaboration came back, we realized we'd found something. well, this will tell us is a soon what like a on been contin. i must k less persona than me call. yeah. unity. people from the koya have longer telomeres, almost
a significantly longer telomeres than people in the rest of the country just on ice . scientists like maria glasgow, are exploring ways of artificially lengthening telomeres in order to slow the aging process. but this does come at a risk digger fata by is, does creeps the danger? is it cancer can develop it because cancer cells are a mortal? and is alina, we're walking a fine line here? yes. do we tell the cells to resist their pre programmed cell death and risk that it will result in cancer reflecting? or do we leave things to run their natural course and let the cells die when their time is alice dropped on his grabs and there is no proliferation. and we just accepted our final destination. it was around 120 and to 125 years will not sponsor this will not from one sponsor, liam shop. but of course, we all know the answer. humans want to test the boundaries and see if they can really live to 150 or 300. and how
far can we go? how much should science interfere in nature is blueprint we don't have to necessarily accept current biological limitation because that's what we do as a species. we're problem solvers. we don't just sit around and get rained on, we build houses. so we may want to transcend normal biology at some point and set goals for ourself beyond just normal concepts of health. ah, ah, when you wonder what the, what is aging, you end up asking how tissue repair. this is a process that is his faith, poorly understood,
says progressively accumulate damage. they age. that when they re to something threshold, they undergo it siege. they become kinessa. i like to describe them as zombies, because you know, they're like in a middle stay between alive and dead. do not either, but they're at the same time, they're really damaging. ha. nissan says would use an alarm signal so that they, all this has in the body, realised the dairy savannah and they go and they repair. the problem is that as we get all these repair says, they are also old and they don't go and they don't prepare. and we accumulate the says that are constantly producing these alarm. this is a phenomenon to his call in from megan o. people who have inflammatory signals innovative, caused by their own success and says that are not eliminated.
we are trying to clack the code of the synopsis. i was trying to understand the wounded of amy, these. how to kill them without killing their nonsense and says in some initial experiments, manuel serrano and his team were able to show that mice lived to longer, once their senescence or zombie cells were eliminated. but that does not guarantee eternal youth. it's a double edged sword. cns themselves play also very good and important role. for example in wound today. if you ever want, if you don't have senescence, the wound will never hear. so you could have a treatment that removes all senescence south and suddenly your terrible side effects. it just means we need more research and all research into
telomeres and zombie cells are only 2 approaches in the race for longevity. and one thing is certain, whoever cracks the code is set to earn millions. alright . so guys, how do i look? i look old. i saw you've seen what we did. we have announced the $255000000.00 res is the largest raise in our industry today? ah, with hong kong has the highest life expectancy on the planet today, which is no surprise because it's very often correlated with well and i hear people
are filthy, rich welfare is increasing dramatically in the region in china and mainland people who are present just 35 years ago, they are now multi 1000000 years and people demand one of the heel for biotech company. i tried to collaborate with a lot of people and they tried to contribute to as many projects as possible. life clinic is a very fun concept where the founder is decided to bridge the starbucks concept with preventative medical care. you choose a cocktail of all kinds of nutrients that will be going into your blood while you're sipping on a juice may offer ivey drips and all kinds of other interventions.
i cannot vouch for some of them. yeah. id in hong kong or anything geared at increasing life expectancy already promises mega box dubious wonder drugs and ib drips are readily available. the region is also attracting biotech companies from around the world. money from wealthy investors has created a much higher startup. he longevity research is hong kong, new dot com boom and brooklyn loya, a new development is that the research is being carried out with business started with massive capital. you got cut, we're investing, we're pumping funds into it and we're throwing cash out and you're from them. that will invariably result in a product. it's an infallible economic model about which we will always work in 5
from noon. we some market, there's a huge market for these new companies. one really is to have treatments for, for the season. so that's where the big box that i'm willing to experiment for myself because there is a lot of data on me and one of the most well studied humans on applied and i try to optimize for high performance at this point in time, i tried to perform my i've tried to call my son in the past. it's very often referred to as a magic drug in longevity, in not in the same line, those mit foreman, but likely to be stronger than the form and it's not without side of things. so there is a chance that you're going to see me beside us and a few others. so we decided to try it on our self in a very controlled mode. and he's not on 0. if
i was interested in anti aging signs since i was a teenager growing up in frankfurt, germany. i had a group of friends who were very interested in science. and at some point, we realised the most important challenge of our generation is to prolong life. we had very lofty goals, i need to tell you in our we have crazy goals. we wanted to study physics, math, biology, chemistry, also we wanted to do space travel, and then the minute you finkel space travel, you realize that you will need decades in or to travel it organized centuries. and so we felt we really need to solve this problem for us to extend our lives span before we can even think about space travel one day by accident. really,
because i did somebody a favor, i analyzed these methylation data. i immediately recognized that epigenetics or methylation is really the data source that has a tremendous signal for aging. he was able to find clusters of genes whose methylation state could tell you how old you were at a particular time. the amazing thing about us is that it works from the day you are created as a fertilized egg cell, all the way until the day that you die. there are more than 200 distinct cell types and the human body. although they all contain the same dna, there is a mechanism that tells the cell whether it is the skin cell or a liver cell, for example, called epigenetics. this involves information that sits on the dna,
resulting in genes being switched on or off. perhaps the best known type of epigenetic change is methylation. the addition or removal of methyl groups on the d n a strand. these changes continue to take place throughout our lives. the dna contains for left us a c, t, g methylation, sometimes attaches to the letter c and modifies it similar to an onslaught by keeping track very carefully. which parts of the dna gain methylation are loose, methylation we can measure aging methylation can be thought of like the rust that accumulates by measuring the amount of thrust we can determine h. so if we are from our glass, the passage of time is measured by how the sand,
how much sand accumulates at the bottom. the d n. a molecule though has 28000000 different our glasses because we have 28000000. let us see in our dna, so by averaging the measurements of 28000000 hour glasses, you arrive at a very accurate measure of age. this is one of the most insightful discoveries in the history of mankind does. we did what the invention of the wheel out is that that was a turning point meeting. i think that was disappear. i'm a very, very important point around like hey, we can measure aging. now the epa genetic clock has revolutionized research into aging, with the simple dna sample. any one's biological age can be determined. however, that can produce some nasty surprises.
my name is mark a toy i've out, and i am steve's identical twin brother. he's my older twin brother, 5 minutes older than me. however, only at birth, measure our epigenetic clock a couple of years ago. then according to one of the clocks i was actually 4 years older than him. which is not necessarily couldn't oh, the, those technologies are enabling us to accelerate aging research dramatically by not waiting until you die. we can now measure where you are in life and measure how different interventions affect that prediction. we pick
this up and applied a i to the same problem and developed many, many asian clocks above all the quest for eternal life requires personal biological data. the digital devices we use every day can provide mountains of it. big data is currently one of the most promising approaches to cracking the agent code. unlike conventional medicine, artificial intelligence can scour the data for hidden patterns to help prevent diseases from developing in the 1st place. this situation looks very similar to taft on a subway. so when you pull your wallet and you don't know who every human on the train looks the same, they move, they. busy different patterns so you to observe many, many of those scenarios in many subways, globally,
to develop really precise address or catching a fee for the subway and your tray and a technologies to recognize those thieves and predict human behavior. and i think nowadays, and advanced countries like mainland china, there are video monitoring techniques that allow you automatically to recognize the fact on movement. so it's very similar to recognizing those proteins that misbehaved during aging and cause trouble yes, so what we're going to do now, we're going to solve a disease very quickly. we're going to solve the cross disease. ai is already poised to increase our life expectancy or so we're told
at the touch of a button, startups can run through thousands of possible outcomes and quickly discovering new medication. all based on data from users of apps like the one that alex shovel room called has developed we recently receive $255000000.00 is from a group of ultra elite investors. so it turns out that we are in the right place and the right time with the right technology. i think that very soon we will see guys like amazon. i'm waiting for those guys to react. guys like facebook. i guys that produce video games, netflix, those people who steal your time, they will come back and try to figure out how to make more time. so you can wasted
on their products. silicon valley is already on board. in 2013 google founded a secret of biotech venture called calico it's longevity, researches carried out behind closed doors with nearly unlimited resources. a group, backed by amazon founder jeff bezos, has also burst on to the anti aging scene, with hundreds of millions and funding altos labs is recruiting top scientists from around the globe to join the project. they include steve horvath and manual serrano . there's even a longevity clinic in the pipeline despite the big players jockeying for position, there is still opportunities for smaller projects, like start up quieting, which is working flat out to develop a self test to measure aging. 15 is
a group of people who are working towards the go of extending house fan in eradicating aging, wedded caesars are all just sort of a group of people with a sort of a fascination for aged sees is an aging itself. we have sort of focused on this idea of biological each itself. we tell you what your bi auto age is into an of an accessible and cheap manner. a lot of i lodge, please just currently are very pricey, which is fine. i mean, the biggest hurdle sent specially for bio hackers and people who are way more interested in the very deep science of aging. but we just want to give and general encapsulation of your eating process for the general population. nina's clock is designed to determine age based on proteins in saliva. although she can only work on a lab one, she turned 16. she's found ways to access the latest data. you go to research paper website and they are supplementary files that we are able to download and see their
data. so that's really cool. sometimes when it comes to us working directly with labs, they send us the data personally. so they tell us, here is the work we have done because it often helps them to in their projects. you know, people like nina are taking advantage of a new paradigm, really in which you can process the data on your own datas available. my laptop that i'm on the one hand i download data, but i also upload a lot of data. i put millions of dollars worth of data into the public domain. i think school. yeah, i think is very good. actually. i know you were making progress on the image of the test recently and to have a good rendering on did you wanna, i'm sure your screen share with them. i look like, you know, just do that right now. hold on. basically right now, i think what we decided was the best ways, like having a multi paddle test with each corresponding to one protein or using the same
technology use and pregnancy tests. so that's pretty interesting. he spent on the test in the sampled area. then from there you downloaded or sort of our app and from there you're able to find out, you know, the ratios of your control to sort of of your protein line. so what, what is there to the concentration of these proteins and based on the color of this test? so here you scan this, you find out that information you entered into our website and you can find a lot more by your router process that we would want to do subscription base. you know, you're going to get several tests here because, you know, slowly can get better as you know, as you improve. she, it was really cool. it would be very hard to conceive. even wanting to do that for me. and i'm from, i don't think anybody here has got to sign up for it. in contrast to nina, either,
gail glenn in costa rica has already ended her professional life, a successful swimwear designer. she was able to retire at age 50. ever since she's been involved in a range of social projects. it's about being unified, it's about to participate and be of service, you know, do what you can care for yourself, but do it. you can to care for others as well. and hopefully you get to a point in life where your basic needs are being met well enough that you have plenty of time to care for others. it boils down to the question, how do i do i save myself or do i save my community? and really, if your community doesn't survive, what kind of life are you going to have a couple years ago, a law was passed to protect the lung heavily. or the centenarians of the area that we live in, which is considered a legal blues on legal, you know,
by law in costa rica. so that's new. nicola is preparing for an increasing number of centenarians. a private initiative aims to raise funds to build a regions 1st, nursing home, rapid advances in longevity, research are prompting a rethink of existing social structures. what will our lives look like if we continue to grow older and older? centenarians did their contribution now at somebody else's turn to take care of them. well, when a via don't nicola where the live that i go those how when we visit the long tables, you ask them, how do you feel about this project we're doing well. yeah, i completely. i'm going to be a $103.00. how are you?
yeah, yeah, go, but that's great. but when you get old, you eventually need some help with a use that any like it and you're lucky to live with your daughter who looks after you get out. there are people who have no support or no family dies, the employer, they left me okay, left me a noisy thing this year and no miss and to valley. yes, i feel happy to have lived such a long life. go with my friends and family are here. i don't, i want to live as long as god wants me to. i the boy that gave you the exact omega . not more hot. as time is of all being here and observing the people who live in this blue zone, i realize how connected they are. the social component is very important.
they don't get cut off and even on a gluten chug today, we know that being part of a strong community is a life extent. meant physician, that's a way for anyone to grow old and hunger might without turning to pills and injection as it alter our dna. i got, well, in my personal opinion, i would not waste time on blue zones when you have to fix the problem of aging. right here, right now, we've reached the point of evolution where we need to accelerate evolution ourself to do this when you to evolve when, when you to change us humans as well. talk with nature has no plan. nature is a random thing, right? but it works. nature is built up life on this planet or the last 4 and a half 1000000000 years. and it is fine tuned and honed and optimized things to an
unbelievable degree of perfection. so you have to be a little bit careful about messing with mother nature. thing with one of the interesting things about super centenarians, and centenarians is that they're immune systems last much better than the rest of us. which is a clue as to the fact that you need to have a good immune system. our to stay alive a long time steve horvath is one of the scientists said to follow the call of amazon boss jeff bezos . but before he embarks on that new task, he's focusing on another promising project. it's the so called trim trial, designed by his colleague greg fi to prefers means system aging. hardly any
other study in the field has prompted as much interest in recent times. the flow of immune cells plays a central role in fighting illness and our bodies. but there's a limited supply of these essential cells. our bodies, thymus gland produces t cells. the superstars of the adaptive immune system. however, once we reach puberty, the thymus begins to shrink. it is replaced by fatty tissue and eventually stops producing new t cells. once we've used them up, our bodies become more susceptible to pathogens and to h related diseases like cancer stroke and dementia. ah, when i saw that you could use growth hormone to regrow the thymus and take immune system function that was down to about 20 percent of the young immune system
function all the way back up to a 100 percent of youthful function. i just thought we have to do something about this, but nobody took any action. so i did an experiment on myself and i re grew my own thymus. he published a scientific paper that described one person and that was himself. in 2016, the trial was repeated. this time a total of 9 test subjects renewed their thymus. v suspected the treatment was having a positive effect on the whole body. but how could he prove it? this person came to me uncertain, can't you help me to analyze a treatment and the minute he said the word fine was rejuvenation. i already said yes him a ha. steve horvath compared blood samples from the test subjects before and after
treatment. and he was just as amazed if not more amazed as we were about the results. if they are confirmed, it will be a sensation. the original intention was, get rid of the fat off the thymus. this treatment had a side effect, an unexpected side effect. it really rejuvenated the methylation the epigenetic clock. all 9 test subjects turned their epigenetic clocks back by around 18 months in a year of treatment. that means they had essentially reversed their biological age by 2 and a half years. we began to get reports from some of the people in the trial that i feel gray, you know, i feel so energetic. now i feel my mind is working faster than it's worked before before the trial was over. this volunteer says, you know, my,
my wife has been telling me that my hairs growing and dark again. and i said, really i, that's interesting. let's have a look. so we looked at his hair, and boy, it was a big, very strong difference. and his hair was darkening all over the place. i need to say we're all very excited about it. but we are also very sober scientists and oh, and therefore we always felt we desperately need a 2nd validation study. and that's really why i continue to work with greg. why i become a study participant, a 3rd study with more test subjects, he aims to corroborate the original results derived. so if successful, find mas regeneration could be the 1st scientifically proven anti aging treatment for human beings. but the scientists need more data. steve horvath and his brother
have volunteered to take part in the trial. as identical twins, they are ideal candidates. steve will get the rejuvenation treatment, and marcus will join the control group. we're now ready for your baseline testing, and this is that the testing that you do before entering the term ex trial. and then we'll assess you after 12 months of treatment and see how you fair at that point. the 1st step is a functional test where you're literally just standing up and sitting back down as many times as you can within 30 seconds. mean entire life ever since we know, i know i had a fantastic break and maybe after 12 months of the term treatment, you'll be able to compete with that. all right, and i'll give you a countdown on your mark. yes. go
live in my in my now that we have your blood pumping. we're going to looking at your epigenetic clock. and then the 80 women and men of different ages are taking part in the latest time of study. and the treatment center also hopes to rejuvenate himself once again. i can't wait any longer, right? i'm getting older. i don't want to age. i'm 71. i don't know how old i will be. that's an open question. i hope but longer than usual, that's all i can say at this point. the main component of the treatment is
