50 is the new 40

Just take Julio Franco, still playing major league ball at 48 -- and now the oldest major leaguer to ever hit a home run.

Watch Aubrey de Grey on why aging can be defeated:

"In a shocking challenge to conventional wisdom, Cambridge researcher Aubrey de Grey argues that the process of aging is merely a disease -- and a curable one at that."

I particularly like his illustration of "Longevity Escape Velocity", showing how he believes a person can expect to live more or less forever provided that they are healthy enough once the relevant medical breakthroughs accelerate.  Aubrey is also head of the Methuselah Mouse Prize, giving researchers an incentive to extend the life of mice.

Misfortune aside, I expect to live well over a hundred years.  Did you see the stem cell discovery today?
