GROW YOUNG AS YOU GROW OLD.
NEXT to air and food in the human economy, comes exercise. We may have plenty of fresh air, and a proper allowance of the right kind of food, and yet, without helpful daily exercise, these will not avail to keep the body in good condition. In answer to the question, "Why do we grow old?" a French writer gives these three reasons: "We do not get enough physical exercise in the open air, we are poisoned by microbes which the phagocytes have not succeeded in destroying, and we are depressed by fear of death." Of the three reasons it will be noted that he gives the place of first importance to lack of exercise. There is nothing else which can take the place of physical activity as a preserver of youth and energy. In short, it is exercise that keeps the body in tune and "up to concert pitch," just as exercise keeps the voice or a musical instrument in perfect tone.—Success.
