Surgeon hopes to inspire folks over 40 to get moving

"No matter how many times we promise ourselves to change unhealthy habits, it seems we continually falter, lured by the couch, the TV and a big bag of snacks. Adults of a certain age could always use a little inspiration. Vonda Wright is happy to oblige. Wright is an orthopedic surgeon who advises and studies aging athletes, including competitors in the Senior Olympics. She also runs a program at the University of Pittsburgh Medical Center that gets aging couch potatoes on their feet and into a 5K walk or run in 12 weeks. She's the author of a new book, Fitness After 40: How to Stay Strong at Any Age."
