The secret of eternal youth can not be found through a study of the body alone, nor the mind alone; it does not have its sole existence in the elements of the earth, nor does it exercise its power exclusively through those forces of nature that can not be seen. When we learn to perpetuate youth, we add immeasurably to the joy of living, and since man is made for happiness, everything that can increase his happiness should be made a part of his life. | How to Stay Young by Christian D.
