To Battle Age, Exercise

Researcher found 'unprecedented changes' in mice who move

(Newser) - Just three 45-minute runs a week were enough to reverse the aging process in mice, according to researchers at McMaster University in Canada.

Scientists Reverse Aging in Mice

Could the process work for humans?

(Newser) - Harvard scientists have reversed the aging process in mice, injecting them with an enzyme that healed tissue and reportedly spurred the growth of new neurons in their brains.
