But anyhoo, bicycling is one of the greatest forms of all-around exercise. Running and swimming are in the same elite class as effective forms of daily exercise for aerobic fitness, strength, coordination, balance, and all the other benefits of exercise. And no other form of exercise (besides walking) fits into daily living as well as bicycling. It's a tremendous benefit to be able to get exercise while you're commuting to work, shopping, going to the bar, or whatever. No, you won't live forever if you ride every day. But you most likely will live a lot longer and certainly have a better quality of life.
