Science usually approaches aging from a mechanical viewpoint, but could there be more to the story?
Why do so many scientists now believe that aging has been programmed by evolution?
Science usually approaches aging from a mechanical viewpoint, but the evolutionary theory of aging has gained more support as we observe the wide variation in aging between species.
The million dollar question: Why do we age?
Theories like the free radical theory of aging propose that aging is an inevitable process of being alive; that every day on this earth exposes the body to reactive chemicals, and aging is simply the gradual accumulation of damage. While we know the body does indeed accumulate forms of damage, the suggestion that this is inevitable is now being challenged.
