''Physical fitness is not only one of the most important keys to a healthy body, it is the basic 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 peak of there capacity when the body is healthy and strong.'' -John F. Kennedy

 I like what Mr.Kennedy's quote says because it is very true if our body is injured or sick our functions are limited keeping a healthy body is extremely important that is why it is never good to do drugs, drink alcohol, or smoke cigarettes. Our body is the most important thing about us with out it we wouldn't be able to do anything let alone live that is why it is extremely important to keep our body's healthy by eating healthy,exercising, drinking water, and many other multiple things. Another reason why i like what Mr.Kennedy says is not much is known of our body and it's true not much is known our body is a masterpiece of artwork which is why it is so complicated to understand.
