Longevity Gene Found

quixote9 writes "Calorie restriction while maintaining nutrient levels has long been known to dramatically increase life spans. Very different lab animals, from worms to mice, live up to 50% longer (or even more) on the restricted diets. However, so far, nobody has been able to figure out how this works. Scientists at the Salk Institute have found a specific gene in worms (there's a very similar one in people) that is directly involved in the longevity effect. That opens up the interesting possibility that doctors may someday be able to activate that gene directly and we can live long and prosper . . . without giving up chocolate."

Our current life expectancy is already putting such a burden on our social security system. When will people realize that quality of life != quantity of life? How is our great-grandkids' generation supposed to support millions of supercentenarians?

Birth rates are already well below maintenance levels in most industrialized countries, and even China is set to see it's population peak soon due to the one child policy. The solution to the problem of too high growth is helping developing countries out of poverty.

We're maybe as little as a century away from actually seeing the worlds population shrinking unless we start increasing lifespans a lot faster than we have.

Who Doesn't Wan't More Time?

If I could get a few more years earlier in life while I still have gobs of energy and relatively no responsibilities... Suddenly four years for a degree wouldn't seem like a huge investment. A year of study abroad in Japan wouldn't be an issue. I might have two hobbies. Long term investments would make more sense. I would take more time to learn more things, aquire more skills, and experience a broader life.

In short, I think living longer would make it a lot easier to live sensibly. As it is, if I have to weight the risks of investing time or taking something I can do now, I end up taking the most courageous and risky courses possible.

I don't think it's a relative thing either. Not in the sense that, regardless of whatever time-span I had, I would always wish, "Wow, if only I had twice as much." In an absolute sense, I just don't think I'll ever have the years to do all the things I want to. It makes it seem really pointless to invest eight years into something (for instance, undergrad + med-school) when it's such a large investment that, by the time I get done, I will have lost many opportunities of youth, but I couldn't put such a thing off because, who wants to invest eight years in something that will only pay off for twenty?

Humanity is robbed. People live crazy lives because we are going to die too soon to live fully, so life is futile. Damn whatever you recognize as the determining factor of our longevity. The light is green to research like this.
