A New Theory on Human Longevity
This is Science Today. People can expect to live
longer today than ever before. This is usually chalked
up to better medicine and healthier living conditions.
But according to James Carey, a professor of entomology
at the University of California, Davis, we may have
evolution to thank for our longer lifespans.
We developed this theory on the longevity…orientation
toward this with humans. And so when we explore this
we find that lifespan extension is what we call self-reinforcing.
That is the greater the lifespan, the greater your
health is and the better your health is more your
life span and so forth.
that longer lifespans allow people to create stronger
social bonds and to make the medical discoveries that
prolong our lives. He says it's these factors-more
than diet and exercise-that will continue to extend
the human lifespan.
There will be things like organ replacement and there
will be disease cures. But I feel that down the road
we'll have a basic understanding of how to arrest
aging at some level.
