1. Henry is a 26-year-old man who doesn't believe in the value of exercise. He asks his friend Sam, who works as a team doctor for a college basketball team, "Why should I exercise? What difference will it make? And what kind of exercise could I even do for the rest of my life? I'm so uncoordinated anyway." How should Sam respond to all three of Henry's questions? How does exercise work to help the body and what lifetime exercise program could Sam suggest? What are some strategies Henry could incorporate in his daily routine to increase his levels of physical activity?
