Did you know that exercise helps you maintain a higher physical function as you grow older?

This is true even if you are over 40. So get up and get moving! In April's American Journal of Preventive Medicine, researchers studied and followed 6.398 adults from ages 39-63 over a 9 year period. Those that began or maintained a moderate level of physical activity had fewer limitations in their health as they aged. Those that choose to be couch potatoes, could not cancel out the long term effects of their spud-like habits.
