EXERCISE IS A HEALTH PILL

Writing in "Harvard Magazine" Frank Hu, epidemiologist at Harvard School of Public Health, noted, "The single thing that comes close to a magic bullet, in terms of its strong and universal benefits, is exercise."

Marilyn Moffat, a professor of physical therapy at New York University and co-author with Carole B. Lewis of "Age Defying Fitness" (Peachtree, 2006) concurs, noting "The data show that regular moderate exercise increases your ability to battle the effects of disease. It has a positive effet on both physical and mental well-being. The goal is to do as much physical activity as your body lets you do, and rest when you need to rest."
