The skin itself is constantly undergoing great changes in its structure, just as is any other part of the body. The outer skin, often called the scarf-skin, is composed of cells, which are short-lived, and are constantly being sloughed off and replaced by younger cells forcing their way up from beneath the old ones. These worn-out and discarded cells form a coating of waste matter on the surface of the skin, if they are not brushed off or washed off.

In our chapter on the use of water as an irrigator for the internal man, we told you of the importance of keeping the pores open, and how soon a man would die if his pores were sealed, as shown by experiments and occurrences in the past. And this accumulation of worn-out cells, oil, perspiration, etc., will at least partially seal up the pores unless the body is kept clean. And then, again, this filth on the surface of the skin is an invitation for stray germs and bacteria to take up their abode there and thrive. Are you extending this invitation to your friends, the germs?
