Can You Fight Aging? Scientists Are Testing Drugs to Help 

A magic pill that boosts life expectancy to 150 years isn’t likely, but an increase in the average lifespan for men and women is conceivable

Say it’s 2050 and you just turned 70 years old. You feel as vigorous after a workout as you did at 35. Your skin has nary a wrinkle. You don’t have to remember where you put your glasses because your vision is still 20/20. Your mind seems as sharp as ever.

Will people eventually routinely live—and live healthily—longer? That’s the vision of the burgeoning field of aging research, where scientists are trying to extrapolate tantalizing life-prolonging findings from animal experiments into medicines that slow, prevent or even reverse the aging process for humans.
