“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. Intelligence and skill can only function at the peak of their capacity when the body is healthy and strong.” -President John F. Kennedy

President John F. Kennedy means that you can only be at your best when your body is healthy and and strong. When you are tired you can’t do anything because your body doesn’t have the energy to do it. If you want to do something you need your intelligence and skill to be at its best and highest peak. For example, when you are sick or tired you can’t concentrate on homework or anything in general. This means that your body isn’t at its peak, it isn’t healthy and strong. Now if your body's health and strong you will be able to do anything. You will feel like you can do anything even what is impossible. Physical fitness doesn’t just mean to be healthy on the outside, but also in the inside. For example, you have to be physical fit in your mind and heart. In your mind meaning that you think positive because thinking positive leads to how you feel on the outside. In your heart it means that you are a kind person. If you aren’t kind you will eventually feel horrible about it, but if you are kind you will feel amazing and that will also affect who you are as a person. I believe this is what President John F. Kennedy meant with this statement.
