Dean Richards' Sunday Morning

Dr. Michael F. Roizen answers questions during an interview at his office at the Cleveland Clinic Wednesday, Dec. 6, 2006 in Cleveland. Roizen, 60, but, by the standards of his RealAge test, he’s the equivalent of a 42-year-old, perhaps a few months younger. Even better, Roizen’s relentless healthy eating and exercise mean he’s increasing the calendar/RealAge gap. (AP Photo/Tony Dejak)
