New Research Could Slow Human Aging

schliz writes "A team of scientists from Japan and New Zealand have helped baker's yeast live 50% longer than usual by artificially stabilizing a genetic sequence called ribosomal DNA. The study's authors say that rDNA is a 'hot spot for production of the aging signal.' Because rDNA genes are very similar in yeast and humans, they say their experiment is a first step towards anti-aging drugs."

      over active people also wear out their body parts with the exertion. there is a happy medium though and i think that it just needed to be clarified. if you run several super marathons every year its going to kill you early... if you run a 5k it's all good.

      I think more studies are showing that intermittent interval sorts of exercise are the best.

      You do explosive runs for short bursts...and then do slow walking, lower activities in between, but these short intense explosions of activity mixed with low intensity activity seems to have the best effect on the human body.

      At least from what I'm reading these days...

      Right. So if I work hard, exercise and deprive myself of good food, I might live long enough for them to slow down my aging process to 1/10th of normal. And I'll have a chipper 4 more years until death, instead of several weeks.

      And as this study shows, genetics can play an even larger part. But try convincing my 84 year old mother that, she's convinced eating right and getting exercise was why she's old and healthy, despite the fact that she's the baby of the family and almost all of her siblings are still alive. One is 99 and owned a bar when she was middle aged, my guess from knowing bar owners she was far from a teetotaler.

      Now I understand what part of my DNA had the health screeners say my vitals showed a healthy forty year old and excellent for someone 61. They thought I must work out, but I get little exercise and eat a lot of junk food, drink a little beer and have smoked pot for four decades. Most people are amazed that I'm over 50. Of course, my rDNA won't keep me from staggering in front of a bus or something.

      If all your grandparents died of natural causes before age 60, no amount of diet or exercise will keep you alive past 70. But perhaps this research will come up with something that will.

      You are over simplifying things. I mean it is great if you are on track to a long and happy life of easy to maintain good health. But I can think of numerous scenarios right now where a person's grandparents die of natural causes before 60 and the genetic issues that person inherits are now treatable with modern medicine. Sure on an actuarial table, it doesn't look good. But it is probably better to say that if all your grandparents died of natural causes before age 60, make sure you have regular checkups with your doctor as you hit your forties and beyond.

      Anecdotally, I had a relative that was a heavy smoker (cigarettes) and overate all the wrong things. Had warnings for years from doctors. He must have been blessed genetically because he still lived a pretty long time. Who knows how much longer he would have lived if he had eaten a better diet, quit smoking and gotten some exercise? Genetics is a part of the picture. It isn't everything. I also think stress has a big role. You sound pretty happy with your lifestyle. That can help. Just stay away from busses when you are drinking beer. :-)

    Other social aspects will be affected too — such as bosses not retiring for longer, thus slowing down careers of the underlings.

    Most everyone's careers would get slowered by that, perhaps proportionally to the lengthening of the active phase of life. But is that a bad thing? It would generally mean that people who get into higher positions would have more experience at average.

    Does this sort of thing cover both the aging of the body and the brain? What's the gain in living to be 150 if your brain stops functioning at any sort of useful level at age 70? Yeah, "lots of people" are still firing on all mental cylinders at age 70, but most are not. If everyone is alive up to age 150 but is a non-productive consumer of stuff starting at age 70 this whole "live long and prosper" thing will be a total nightmare. Even if brain aging is held in check, do we have the resources to support that many human beings on this planet?

      I know what you meant, but I get really tired of people acting like the brain and the body are something separate. The brain is part of the body; a complex and unique part, to be sure, but essentially it's just another organ. So if we can slow down aging generally, most likely our brains will benefit just as much as the rest of our bodies will.

    I agree that this would create massive social issues.

    However the idea that delaying the retirement age is politically difficult is only valid in the current context. In a society where people live 50% longer I think there would be great political will to adjust the retirement age to compensate.

    It's been done before in response to much weaker motivation.

    It may ultimately have big economic advantages. For example:

    1. Increased incentive to take care of one's health.
    2. Better return (over a longer lifetime) on the costs of raising and educating a child.
    3. Increased incentives to save.
    4. Better depth of experience for making decisions by adults.
