Remember. 1. Overworking the eyes is as injurious as overworking the stomach. 2. Keep your hands away from your eyes; germs on your hands may get into your eyes and cause them to become sore. 3. You overwork your eyes when you try to read or write in a poor light or in a bad position, as when lying down. 4. You overwork your eyes when you try to study with eyes that are not properly focused. 5. Keep your fingers out of your ears. 6. Take care of your ears by letting them alone.
[CHAPTER XIV]
CARE OF THE SKIN
If you break or cut the skin on your body, you make an opening through which germs can get in. You cannot always help breaking your skin, but you can always wash the break with soap and water, and put a clean cloth over it to keep out germs.
The work of the sweat glands
The work of the little sweat glands is very important to your health. These glands are just as important as the kidneys, and if they did not do their work, you would die very quickly. If your body is covered with dirt, the work of these glands is seriously interfered with; and when the sweat glands are not doing their full amount of work, the kidneys must do more than their share. It is never right to make one part of your body do the work intended for another part.

When the body is dirty, not only are the sweat glands interfered with, but the little sebaceous (oil) glands become plugged up, and blackheads appear on the face and body.
