Even the elderly should exercise

It has been found that older runners live longer and suffer fewer disabilities than healthy non?runners. This observation applies to a variety of aerobic exercises, including walking.

A study by authors, from Stanford University School of Medicine, published in the Archives of Internal Medicine has shown that being active reduces disability and increases survival.

There are benefits of vigorous activity late in life. Earlier many experts believed that vigorous exercise would actually harm older individuals. And running, in particular, would result in an epidemic of joint and bone injuries. But this new study proves otherwise.
Exercise is like the most potent drug. Exercise is by far the best thing you can do.
