This is one way of saying that the processes of repair and waste are constantly going on in the body. Every action of the body, every impulse of the mind uses up some cell-matter, which must then be passed from the body as waste. This is called tissue disintegration. New cells to repair tissue waste are built up from the nutriment which the blood carries from the alimentary canal after the process of food digestion is accomplished. This is called tissue construction, or the process of assimilation. Technically, these are the metabolic, or destructive and constructive processes. Both are essential to health and life. Any substance taken into the body, which will interfere with these processes of nutrition and waste is inimical to health, and in time of disease, dangerous to life.
Alcohol is such a substance.
The cells and tissues of the body which are touched by alcohol are more or less hardened and injured by it, hence are less perfectly nourished
