"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 activities of the mind is subtle and complex. Much is not yet understood. But we know that 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 I believe this means is that the healthier you are the less you have to worry about getting sick which means you won't be stopped from learning or getting better at something. Being physically fit means you have more free time to study and still reap the benefits of being healthy. One of those rewards is a longer life expectancy and not having to cut your life short by using drugs. So listen wisely always do the right thing and be active and healthy and don't take part with people who use drugs that would damage your body and ruin your life of success and prosperity.
