Which Athletes Live the Longest?

You hear it in the gym -- a burly weightlifter mutters that he could bench press three of the guys on the treadmills. A guy on a treadmill snickers that the weightlifter could never catch him. A soccer player says that thinking on your feet and anticipating where the ball will go takes much more skill than just doing the same thing over and over, and that she's the most agile person in the room. Athletics demands self-discipline, and each sport develops different skills and strengths in the people who play them. In addition, we all hear the public service announcements telling us that exercise is important for our health. But are all sports created equal when it comes to health benefits? And what about the biggest health benefit of all -- staying alive? Scientists have long since reversed that opinion. Now physiologists, biologists and physicians are comparing different types of exercises and sports to see whether one is better than another when it comes to living longer.
