For years it was thought that children could not perform under extreme physical activity because they're cardio vascular system is not quite developed.

We most likely won't see any 12 year old pro sports teams on the rise in the near future but are we sheltering kids these days? We should acknowledge that they are tougher than we give them credit for. Science has proven that they're probably stronger and in better shape than most adults.
