Very few realize how essential water is to digestion and to the digestive canal after the process of digestion is completed; and that it has physiological effects on the system generally is less widely known. There exists a great natural demand for water to carry on the normal functions of the system; for both atmosphere and heat draw moisture from the body, and a considerable amount is utilized in the processes of our daily work and in unexpected efforts. An organism composed of almost eighty per cent. of water requires a generous supply for subsistence--a supply equal to the expenditure of vitality involved in carrying on the numerous functions of body and brain. Some day it will be discovered that water is mainly the element employed in psycho-physiological processes. Water is easily changed to air, and atmospheric air to water, in the system. The generous consumer of air and water will have a good stock of vital or of psychical force on which to draw for the process of thinking. A thinker is a creator, and he must be successful if his thoughts be rightly directed and he have an ample supply of liquid food--water. CHAPTER IX. WHEN ENEMAS SHOULD BE TAKEN. Method is imperative in this strenuous life of ours. Nature in her universal operations seems to sanction a uniform system in our daily conduct. Had we a regular time for doing things, periodicity would be established in our sleeping, eating, bathing, defecating, work, recreation, etc. Unfortunately, we are prone to ignorance, self-indulgence, procrastination, which render us careless and reckless in regard to the common-sense conditions of normal living; and before we are fairly out of our ’teens we begin to bear a crop of proctitis, colitis, constipation, etc. It is in this way that periodicity as to stooling is lost, and whim, convenience, or necessity takes its place. As a result, we dribble or strain under the fecal and gaseous burden. This happy-go-lucky method accounts for much of the gastro-intestinal disorder complained of by so many, who “want to die” when the painful neurasthenic blues hover around and pervade their bodies like a dense fog. The insidious manner in which proctitis, colitis, constipation, and self-poisoning progress from mild through medium to severe stages does not, generally, alarm the victim of intestinal neurasthenia until many years have elapsed, and one or more of the vital organs have become diseased, and the whole system is thoroughly under its toxic effects. Thus, slowly, are the various segments of the gastro-intestinal canal changed to an abnormal condition.
