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

This is a clear and basic understanding of how keeping our body it helps us do things. IF we dont keep it healthy we cant do much and just get lazy to do things. We can always learn from this to help our body stay healthy. Another thing you can be doing is working out , it helps the body and the brain to. You need to do a lot of things to stay healthy and it can help you and your brain over come many things. In school if you work out in pe there is a chance that you will do good in your classes since your body is all motivated. SO John F. Kennedy made a great statement here. I think everyone should follow this statement to help their selfies in their life .So that means that you are choosing the right 24/7. So do this to help your intelligence.
