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; that hardy spirits and tough minds usually inhabit sound gods.

The effort to improve the conditions of man, however, is not a task for the few. It is the task of all nations-acting alone, acting in groups, acting in the United Nations, for plague and pestilence, plunder and pollution, the hazards of nature and the hunger of children are the foes of every nation. The earth, the sea and the air are the concern of every nation. And science, technology and education can be the ally of every nation.

Great crises produce great men, and great deeds of courage.
