Researchers have discovered yet another benefit of exercise: It not only helps skin look younger, but may even reverse skin aging in those who begin exercising later in life.

Mice that had access to running wheels had an opposite response: They maintained healthy hearts, muscles, brains, and reproductive organs, and their fur never turned gray.
