Physical Fitness 
''physical fitness is not only one of the most important keys to a healthy body, it is the basis of dynamic and creative intellectual activity. the relationship between the soundness of the body and the activities of the mind is subtle and complex. much is not yet understood. but we do know what the Greeks knew: that intelligence and skill can only function at the peaks of their capacity when the body is healthy and strong.''
 ~ John F. Kennedy

what this quote means is that if your tied from school your not going to want to go home do homework or do anything. your just going to want to go rest if your really tired. But on the other hand if your full of energy  your gonna want to stay for tutoring do your home & go to basketball practice. you can be full of energy by maintaining a healthy body. for example, eating healthy, doing exercise etc. if you don't have a healthy body and your over weight your gonna get tiered easily and want to eat more. if that happens its gonna be harder to get back in shape and go back to a healthy body. its not only just being in good shape but also if you have a disease your not gonna  want to live anymore. so thats why it is god to eat healthy so can prevent disease  from coming to you and getting really sick. over all maintaining a healthy body is the best thing to do.
