This is a neat little site. Interesting take on the various perspectives on aging.

"Why do we age? This may seem like a silly question. The more you drive, the less tread there is on your tires — simple wear-and-tear. Why should our bodies be any different? But would you still expect your tires to need replacing every 40,000 miles if they had a built-in system that sensed when rubber wore off and then re-grew it according to an internal blueprint?"
"Another popular theory of human aging is called the "free radical theory." Free radicals are chemicals that accumulate in our cells from the environment that can react with and damage DNA. Prolla's team measured the levels of a common free radical in the normal and mutant mice at different ages — but they found no difference. This led the team to conclude that the higher rate of cell death could cause aging even in the absence of free radicals." - Eva Gladek |
