The weakling has been compelled to be careful. Habits of moderation grew
upon him in youth, and his health has improved as he has advanced in
years. He may never be strong, but great physical strength is not
essential to health. Thus the strong often perish and the weak survive.
If both classes lived with equal care the strong would outlive and
outwork the weak every time.
It is necessary to give the skin some care if continued good health is
desired during the latter part of life. The skin has a tendency to grow
hard, which should not be allowed. It will always remain soft if it is
properly cared for. When our ancestors roved forests and plains with
scarcely any attire, the skin exposed to the rain and the sunshine,
there was no need to give it special care. It served its purpose of
protecting their bodies and was exercised through its immediate contact
with the elements in all kinds of weather. Now the skin has little
opportunity to exercise its protective function and the result is that
it is not as active as it should be. The skin must be active to rid
itself of the waste that the blood-vessels leave with it. The best
exercise for this important organ is rubbing.
