Brief Summary
The video discusses the science of aging, distinguishing between chronological and biological age. It highlights the roles of genetics, lifestyle, and external factors in the aging process. The video also touches on current research into slowing aging, including targeting zombie cells and increasing NAD+ levels, and how these advancements may extend health span and lifespan.
- Aging occurs on a cellular level and is influenced by both genetics and environmental factors.
- Lifestyle choices, such as diet, exercise, and cognitive activities, significantly impact how we age.
- Current research focuses on increasing health span and lifespan through interventions like targeting zombie cells and boosting NAD+ levels.
The video starts by pondering the concept of aging and its inevitability for all living beings. While growing old is often not something people aspire to, it is presented as a privilege. The video challenges the common perception that our aging patterns are solely determined by genetics, asserting that genetics only account for about 30% of how we age. This suggests that individuals have considerable control over their aging process through lifestyle and environmental factors.
Aging occurs at a cellular level and is influenced by external factors like environment, diet, and physical and cognitive routines. The video introduces a hypothetical person named Maya to illustrate how different life stages and choices affect aging. In her childhood and early adulthood, Maya experiences optimal development by engaging in activities like volunteering, which slows cognitive decline, and learning new languages, which enhances thinking skills.
As Maya enters her 30s, her metabolism begins to slow down, and she starts losing muscle mass. Maintaining a healthy diet and exercise routine becomes crucial. In her 40s, the body starts to shrink, with height decreasing due to changes in bones, muscles, and joints. Exercise can help mitigate this. By her 50s and 60s, Maya faces new physical limitations such as impaired vision and hearing, and decreased skin elasticity. Despite these challenges, she embraces aging, symbolized by her gray hair.
The video explores the potential of technology to slow down aging, noting that humans currently live an average of 90 years. It mentions Jeanne Calment, who lived to be 122 years old, and Lucille Randon, who is 118 years old. The focus of modern medicine is shifting towards increasing health span—the number of years a person lives in good health—rather than just lifespan. A century ago, the average lifespan in the United States was only 53 years, highlighting the significant progress in longevity.
Research indicates that people are staying younger for longer, with 60 becoming the new 56 and 40 becoming the new 37.5. Dr. Morgan Levine's work distinguishes between chronological age (age by birthdate) and biological age (age based on health). Biological age is determined by factors like exercise, diet, and stress levels.
The video discusses scientific efforts to slow aging by targeting "zombie cells," which lose their ability to replicate and contribute to aging. Another approach involves multiplying NAD+ cells, which are crucial for cellular repair and function but decline with age. NASA is also exploring these technologies to protect astronauts from the accelerated aging effects of radiation during Mars missions. The video concludes that while achieving Benjamin Button-like reverse aging may not be possible, scientific advances are paving the way for increased longevity.

0:00 now imagine being born old and getting younger for the rest of your life well we've seen this movie before haven't we Benjamin Button taught us some valuable lessons as we get older our body changes our habits our likes and dislikes our emotional intelligence all of this changes with time but what exactly is aging and how come every living being on the planet is subject to it ever since we were little people have been asking us what do you want to be when you grow up rarely does anyone answer oh I want to be old yet as Groucho Marx once said growing old is something you do if you're lucky now picture yourself in 20 years time what do you think you will look like
0:45 your face will have a few extra wrinkles perhaps but I bet you've just pictured a version similar to your father or Mother We tend to use our progenitors as molds of how we'll look when we grow old yet genetics is only responsible for 30 percent of our aging patterns the good news is we're not 100 percent faded to play out the same health problems or aging patterns as our parents that's nothing but a popular myth you have real control over how your body ages now let's get one thing out of the way aging happens on a cellular level you start aging from the moment you are born and you continue aging every single day of your life Gump even while you're watching this video but most of what
1:31 ages us has to do with our interactions with external factors the environments we live in the food we eat and our physical and cognitive routines all of of that counts maybe Maya can help us understand that better Maya was born a healthy baby smart curious and happy well into her childhood and early adulthood Maya's on what's called an upward curve of development her brain and bones are growing to their full potential our brains age well into our 20s so it's good to give them extra stimulus in order to guarantee their best development it's good then that Maya volunteered at the local dog shelter since she was little studies show that giving back slows cognitive decline in other words it makes your
2:18 brain healthier for a longer period of time learning new things such as a new language is also good for that period of life it increases your thinking skills and mental agility and delays the Aging of the brain then comes the 30s supposedly the prime time of one's life a decade when happiness levels are increasing but that also when Maya's metabolism starts to decrease by two to three percent every 10 years around this decade she'll begin to lose muscle mass as well so keeping up that yoga or muscle building routine will be the best antidote eating healthy might not have been Maya's priority until then but it sure will be now she'll start eating foods that will help accelerate her
3:04 metabolism like ginger and other Foods during her 40s Maya's body will start to shrink every 10 years after the age of 40 we lose about half an inch of our height this happens due to changes in Bones muscles and Joints there's no way to fully stop the shrinking process but exercise will help to reduce it a bit during your 50s and 60s Maya's Offspring will be off to school and out of the house so she'll feel Freer than she has been for the last few years but she'll have to come to terms with some new limitations regarding her body her vision and hearing are more impaired one-third of Americans in their late 60s and early 70s have hearing loss but she can use glasses and hearing aids if it
3:50 comes to that her skin has lost a lot of its elasticity so the wrinkles are very apparent she might regret all that sunlight she got while not using sunscreen when she was younger but on the bright side Maya's rocking in all gray hairdo and loving it Maya is embracing the cycles of Life some of her friends are turning to the newest Technologies in order to slow down or even reduce the Aging of their bodies humans live an average of 90 years which is already a lot if you ask me to this day the longest living person was around 122 years and 164 days her name was Gene Kalman a French woman the oldest person alive as I speak is also a French woman
4:36 Lucille Rendon she's 118 years old one can't help but wonder is there something in the water over there in France the promises of new technologies show that more people could be living to 110 or 120 years old some questions remain though why would someone want to live that long and should Humanity aim for that goal collectively one of the main focuses of medicine today is to increase People's Health span instead of just increasing a person's lifespan also known as the number of years someone will be alive medicine is trying to increase our quality of life and we don't have to travel into some distant future to say we are living longer than before I mean a hundred years ago a
5:23 person's life span in the United States was around 53 years so yes we are now living longer if you look at some old photos you'll see that people also look much younger nowadays than they did decades ago if you look through old yearbooks from the 70s you'll notice how 19 year olds look 30 or even 40 according to our modern standards researchers at Yale and USC have found out that we are in fact staying younger for longer their results suggest that between the early 1990s and the late 2000s 60 became the new 56 and 40 became the new 37 and a half according to Dr Morgan Levine's newest book true age humanity is on the brink
6:10 of slowing the aging process down Levine says we have two ages our chronological age the one we celebrate on our birthdays and our biological age this means that you can be 30 years old chronologically but be 25 years old or even 35 years old biologically what will determine your biological age is basically how healthy you are which takes us back to what we said at the beginning of this video how's your exercise routine how healthy do you eat are you able to maintain a low stress routine other than that science has identified a very specific type of cell that they believe is responsible for human aging they're popularly known as zombie cells ew due to some stress these cells lose
6:58 their ability to replicate and instead of being ejected by the system they remain in our bodies they don't replicate and cause our bodies to age more and more some scientific experiments have been conducted they targeted these zombie cells trying to remove them from people's bodies but it hasn't been 100 proven that this can hold aging another modern bed is on multiplying NAD plus cells you see our cells are made out of hundreds of Parts all these parts constantly need to be destroyed cleaned up and rebuilt the thing is as we age this process becomes less effective we produce less and less of the so-called NAD plus coenzyme which is like a self-regulating part of our
7:44 cellular structure it reminds ourselves of their reproductive functions when we are 50 years old we have about half of the NAD plus we had when we were 25 years old low amounts of this coenzyme are linked to a bunch of diseases and the aging process itself Maybe by increasing these amounts we could slow down our body's decaying processes and increase people's lifespan now here's a fun fact this even got NASA interested and they're now making sure to guarantee some of this technology to their astronauts on future Mars missions after all they'll be exposed to a lot of radiation which will end up affecting their molecular and DNA structure probably making them age faster due to this exposure maybe it will never get to
8:31 experience life as Benjamin Button but it seems like our scientific advances are heading to provide longevity for us humans that's it for today so hey if you pacified your curiosity then give the video a like and share it with your friends or if you want more just click on these videos and stay on the bright side
