Two or three nights every week, I help a bunch of young kids in east Allentown learn how to play baseball. Some are very well coordinated for their age, but none has an attention span longer than two seconds. That's why baseball can be dangerous for young kids, regardless whether wood or aluminum bats are used. After two seconds, most of them are looking at their mom or have their heads down. Infielders kick dirt or go into some trance. Outfielders pull grass and count clouds. One of them actually took a nap. Invariably, the kid paying least attention gets nailed. When I was a kid, it happened to me regularly. I eventually played the "left out" position.
