How to Cure Aging – During Your Lifetime?

Health is the most valuable thing we have in life, but we tend to forget that until we lose it. We’re living longer than ever before, which is great, but an unforeseen consequence of this is that we also spend a larger and larger portion of our lives being sick. Getting old currently means spending more time in pain. So scientists are trying to shift the attention of the medical community from optimizing lifespans to optimizing healthspans, the part of our lives during which we’re disease free. To do this, we need to attack the root cause of almost all bodily defects: aging itself. Unbeknown to most people, the science of aging has made enormous progress In the last few years, with human trials about to begin in the near future. Let’s look at three examples of discoveries that might benefit people who are alive right now INTRO 1: senescent cells. Your cells have an expiration date. Each time one of your cells divides, it copies its chromosomes. Because of the way this works, they lose a tiny bit of DNA at the ends. This could be catastrophic, so to protect themselves we have long segments of DNA called telomeres that sort of act like the stiff bits at the end of shoelaces, but they shrink with every cell division. In some cells, after a number of divisions the telomeres are gone, and the cell becomes a zombie, a senescent cell. Senescent cells stay around and don’t die. The older you get the more of them are inside you. They harmed tissue around them and are linked to many diseases that accompany old age like diabetes and kidney failure. But what if you could kill them off? Scientists genetically engineered mice so that they could destroy their senescent cells as they pleased. Older mice without senescent cells were more active. Their hearts and kidneys worked better, and they were less prone to cancer. Overall, they lived up to 30 percent longer and in better health than average mice. Since we can’t genetically engineer all the cells in the human body, we need to find another way to get rid of our senescent cells. But how do we kill them without harming healthy cells? Most cells in the body commit a programmed cell suicide when they’re damaged, but senescent cells don’t. It turns out that they underproduce a protein that tells them when it’s time to die. So in a late 2016 study, mice were given an injection of this protein. It killed 80 % of all their senescent cells, while causing almost no harm to healthy cells. The treated mice became generally healthier and even regrew lost hair. As a result, there are a number of new companies looking at treatments involving senescent cells and the first human trials will start soon. 2: NAD+ Cells are made of hundreds of millions of parts. They’re the structures, machines, messages, and the catalysts that make reactions happen. All these parts constantly need to be destroyed, cleaned up, and rebuilt. As we age, this process becomes less effective and so parts become crumpled, bunched up, or are removed slower, or they are no longer produced in the quantities we need. One of these parts is NAD+, a coenzyme that tells ourselves to look after themselves. At age 50, we only have about half as much in our bodies as we do at age 20. Low amounts of it are linked to a whole bunch of diseases from skin cancer to Alzheimer’s, cardiovascular disease, and multiple sclerosis. But NAD+ can’t enter cells so we can’t get it as a pill. But scientists notice that other more flexible substances could enter cells and would then turn into an NAD+ inside. In 2016, multiple trials on mice showed that they boosted the multiplication of skin, brain, and muscle stem cells. They were rejuvenated, had a higher ability to repair their DNA, and had a slightly increased lifespan, This even got NASA interested, which is looking for a way to minimize the DNA damage astronauts would be exposed to from cosmic radiation on Mars missions. There are human trials being planned right now, but it’s too soon to say if this will boost our healthspan or even lifespan. But NAD+ is a serious candidate and could become the first human anti-aging pill. 3: stem cells Stem cells are like cell blueprints that sit at various places in the body and copy themselves to produce a steady flow of fresh young cells, but they decline as we age and so we decline too. Without new parts, human bodies break. In mice, scientists observed that as the stem cells in their brains disappeared, they started to develop diseases So they took stem cells from baby mice brains and injected them directly into the brains of middle-aged mice, more specifically the hypothalamus, a polyp that’s involved in regulating a lot of bodily functions. The fresh stem cells reinvigorated older brain cells by secreting micro RNAs that regulated their metabolism. After 4 months, brain and muscles worked better than those of untreated mice and on average, they lived ten percent longer. Another study took stem cells from mice embryos and injected them directly into the hearts of older mice. As a consequence, they had improved heart function, could exercise 20% longer, and weirdly enough their hair regrew faster. Conclusion What all of this tells us is that there is not a single magic bullet with which to cure aging. It requires a complex array of different therapies. We can kill off senescent cells to clear away the junk, give ourselves fresh new stem cells to fill the gap, all while regulating the metabolism of the other cells using medication. This video comes with a big caveat. After all, these studies have been carried out on mice. There’s no guarantee the same therapies would work in us to the same extent, but they are proof of concepts. To learn more about how we can modify our own healthspan, we need human trials. We’ve only covered a tiny part of the research that’s being done right now, and only scratched the surface of these ideas. The field of healthspan extension needs more attention and funding. If it gets it, all of us might enjoy growing old without pain If you now want to support the research on aging directly, you can do so at, a community of people actively supporting the scientists working to cure aging.

i think that aging is a thing that we are all destinated too, because every cell go futher, and not all of them can be replaced.

What is the point of trying to cure aging when kids now the age of 14 may not even age to see 50 because we will have scorched our own planet. Think on that.

Certain cancer cells don't go through the senescence process if Im not mistaken, meaning that if our technology can reach the required point, couldn't we use a process to reverse aging, similar that of stem cell research combined with genetically engineered cancer cells?

I think fasting is the solution for cell renewal inside and out, and for longevity. fasting 16 to 19 hours everyday with five hours on eating, but eating healthy foods and fruits and vegetables. and plenty of good water. avoiding direct sun as much as possible, no smoking, no drinking alcoholan.
but most importantly communicating with God through prayer. also standing in the gap for others when you are needed.

Had a Grandmother that was 96 years and 9 monthes old, the creepy thing is that she could still walk and even run a little and acted all healthy untill she was about 93 years, its like she never aged untill than. But she were healthy her whole life, training, eating only good things, so keep urself healthy guys, never to late to start over, and i hope u live a wonderful life ❤

I would want to live to be 200 the first person to be 200 so I’m famous. I don’t want to live even longer because my bones will probably get very weak therefore me breaking more bones and I have never had a broken bone but I heard it is EXTREMELY PAINFUL.

So basically if humans want to stop ageing then we we need to inject younger versions of what is causing us to age.

I'm not sure what we're doing for humans, but the mice are winning. They're smarter, younger, age slower, reproduce newer stronger cells faster, have a better metabolism. At this point, I'm kind of jealous.

I want to live longer just to witness new inventions, discoveries, mars colonization and space travel.

Nothing else in the world is so attractive to want to live forever.

Why do people test on mice it’s a waste of time and money. The reason is because rats have different dna than we do so they react differently to a lot of things than we do. For example. Scientists one time tested a cancer cure on mice and it worked. But when they did it on humans they all went into cardiac arrest. So I don’t see why we use mice.

I'm actually really happy with these answers, we all have to die eventually, so the thought of never aging was a bit unethical (if that's the right word), but i like this because, instead of becoming immortal, just make your life healthier.

Love this.

I need this so i can see humans advance to possibly saturn in a long long time. Also, to stop aging might be frustrating for some people who want to die naturally.

As health span science progresses, "money span" becomes an even bigger challenge as millions of people will struggle to finance their lives. Who wants to live an extra 10 to 20 years poor? 🙁

why don't we mix them all? kill of SENESCENT CELLS! and then give really flexible cells that turn into NAD+ when in contact with blood. and then put good'ol fresh young cells from species that can live forever or if we need to get them from our own species no problem. species that live forever cells can work? ABSOLUTELY MAKE ME LIVE FOR 1 BILLION YEARS I WANT TO SEE MY 100+ GREAT GRAND CHILD and see judgement day when God kills us all off.

i wanna live forever but like if i want to i can be like "science kill me" if im done so im like mortal but i choose when i die
