MORE PHYSICAL ACTIVITY = LONGER LIFE

Study finds leisure-time physical activity extends life expectancy as much as 4.5 years

"We must not underestimate how important physical activity is for health - even modest amounts can add years to our life," said I-Min Lee, M.D., Sc.D. , professor of Medicine, Harvard Medical School, Cambridge, Mass., and senior author on the study.

Physical activity has been shown to help maintain a healthy body weight, maintain healthy bones, muscles and joints, promote psychological well-being, and reduce the risk of certain diseases, including some cancers.
