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 health and strong”  President John F. Kennedy

What I think this quote is trying to say is that physical fitness is not the only thing to have a healthy body, but so is Intelligence. When you have a nice personality , your body is healthy and fit. It is good to have a nice personality because it makes you into a nice person. Everyone is going to want to be friends with you if you are kind and intelligent. People with unhealthy bodies continue to do the same bad things. They don’t have intelligence so their body isn’t fit. People who do drugs is one example of not having a healthy. Having good skill and intelligence leads you to good high stakes. Always try your best and have a healthy body. Having a healthy body means you are a CTR person and that is the best thing you can be.
