Physical education trains children to be physically and mentallly active, fit and healthy...for life. It is said that if you have an active body, you have an active mind. So, for every child it is important to do P.E., because they get fit especially girls and boys, and have a healthy life. It's important to do P.E. in school because the teacher knows what are the best exercices for your age. I think the best sport for everyone, especially children is SWIMMING; which helps children to strech their body, and also to active to thir mind quickly. Don't forget that a healthy life is a happy life and a healthy life is also an active body and an active mind! Like George S. Patton Jr. said "An active mind cannot exist in an inactive body."
