"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."- John F. Kennedy

 What this quote means to me is that physical fitness is the key to be a healthy and happy person in life. If you want to be happy in life you need to be in good physical shape. You need to be in shape mentally and physically in order to be happy in life.
