Drugs are too easy to obtain today. Some day people will be so enlightened that they will not allow themselves to be medicated. This is the trend of the times. Until such a time comes, society should protect itself by making it very difficult to get any of the habit-forming drugs. If necessary, the free hand of the physician should be stayed. Much of the confidence blindly given him is misplaced.
CHAPTER XXI.
CARE OF THE SKIN.
The skin is neglected and abused. Very few realize how important it is to give this organ the necessary attention. If we were living today as our ancestors doubtless lived, we could neglect the skin, as they did. They wore little or no clothing. The skin, which formerly was very hairy, served as protection. It was exposed to the elements, which toughened it and kept it active.
Today most people give the skin too great protection, and thus weaken it. The result is that it degenerates and partly loses its function with consequent detriment to the individual's health.
A normal skin has a very soft feel, imparting to the fingers a pleasant, vital sensation. It either has color or suggests color. An abnormal skin pleases neither the sense of seeing nor feeling. It may feel inert or it may be inflamed.
The skin is a beautiful and complex structure. It is made up of an outer layer called the epidermis and an inner layer, the true skin or corium, which rests upon a subcutaneous layer, composed principally of fat and connective tissue.
The epidermis is divided into four layers. It has no blood-vessels and no nerves, but is nourished by lymph which escapes from the vessels deeper in the skin. It is simply protective in nature.
The true skin is made up of two indistinct layers, which harbor a vast multitude of nerves, blood-vessels and lymph-vessels.
In the skin there are two kinds of glands, the sebaceous and the sweat glands. The sebaceous glands are, as a general rule, to be found in greatest numbers on the hairiest parts of the body and are absent from the palms of the hands and the soles of the feet. They throw off a secretion known as sebum, which is made up principally of dead cells that have undergone fatty degeneration and of other debris. The sebum serves as lubricant. It is generally discharged near or at the shaft of a hair.
