LOS ANGELES --
You might get plastic surgery to get a little of your youth back, but there may be a cheaper, healthier way to take ten years off your life. Get off the couch, and walk.The latest research shows that regular walking can reduce heart disease by up to 50 percent, decrease osteoarthritis pain, and boost your aerobic fitness to levels of a much younger person. Experts say start slow, and build up to half an hour, three times a week. Use a pedometer to count your steps, and mix things up by changing your route.
