Some doctors think it's even powerful enough to delay the aging process by more than a decade. That's because activity such as running, jumping rope, bicycling, even brisk walking, improves the body's ability to take in oxygen and use it. And that seems to affect organs through out the body, helping older people to maintain a high quality of life and live independently
The review in the British Journal of Sports Medicine also finds that keeping up a brisk level of activity helps prevent injury and illness.
