Dr. Wright, an orthopedist, has created a medical program specifically designed to target the fitness and performance needs of mature athletes. "No matter how fit we may have been at 20, we're very different people after 40. You have to understand your body and approach exercise and injury in a new way," according to Wright. "The good news is that not only can we retain the vigor of our youth, we can actually perform as well, if not better." Wright practices at the University of Pittsburgh's Center for Sports Medicine. She's also the team physician for the Pittsburgh Steelers. Freelance writer Winter became co-author after receiving a cold call from Wright about the book project.
