The Greenwich Time reminds us that moderate exercise brings enormous health benefits, especially in the elderly. "I would say there is probably no single group in the United States that has more to gain from exercise than the elderly," said William Evans, director of the Nutrition, Metabolism and Exercise Laboratory in the Department of Geriatrics at the University of Arkansas. The rest of us benefit from exercise as well. Studies consistently show benefits in health and longevity resulting from moderate, easily accomplished exercise. If you are not exercising, you should certainly talk to your physician about it.
