"This is the first clear demonstration that, in a primate species, we're inducing a slowdown of the aging process -- showing increased survival, resistance to disease, less brain atrophy and less muscle loss.

After two months on the stimulant, the mice rebounded to score just as well on memory tests as normal mice of the same age that had never exhibited signs of dementia.
