Twenty to 30 years ago, recreational activities for children usually meant going outside and playing running games or riding their bicycles or playing other physical games, like hopscotch, jumprope, kickball, things like that. Children were much more physically active, which was good for their overall health.
These days, television, computers and video games have become increasingly popular as pastimes for American children. Unfortunately, these activities require little physical energy; kids just sit there. As a result, children aren't exercising very much, they are getting fatter at a younger age, and many are unable to pass the most elementary physical fitness tests (like running 50 yeards, or doing 25 push-ups).
