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 peak of their capacity when the body is healthy and strong."- President John F. Kennedy

What this quote means is that having a physical body is not a way to have a healthy body and life. If you don't have a healthy body and you're just lazy not doing anything it's going to be hard for you to do anything. Having a mind that does the right will make physical choices easier. Intelligence will function at it's peak of their capacity with a healthy and strong body. You make right choices when you're mind is in focus.
