Sir Andrew Clarke used to have his patients chew a definite number ol times on each bite—say thirty times. Even so great a man as Gladstone submitted to this rule and gradually learned to accustom himself to eating very slowly. Fletcher's system of chewing the food until it passes down the esophagus of itself without any swallowing effort is a better rule. It is a surprise to most people how unconsciously swallowing can be accomplished in this way and how little liquid is needed in order to prepare food to be swallowed. The formation of the habit, however, is not an easy one. Persistence and frequent reminders are needed, or else the beginnings of the habit are soon dissipated and old bolting habits reassert themselves.
Water Drinking.—In drinking, habit is as supreme as in eating. The majority of people who work outside and perform muscular labor crave and take an abundance of water. Many of those who live indoors, especially in steam-heated houses, may need it quite as much if not more, but get out of the habit of drinking water. As we need about three quarts of water per day for use in our economy, this no water habit often becomes a serious factor in the production of physiological disturbances. We have replaced water drinking and the milk drinking of the olden times by tea and coffee, and as these are stimulants, habits form very readily with regard to them. I have known people who were sure they would be miserable without their half-dozen cups of tea or coffee each day, and who actually would be miserable for a few days, when deprived of it. They were seriously impairing the efficiency of their nervous system by so much stimulation. Unfortunately, it is just those whose nervous systems have least stability, and are already the subjects of more stimulation by conscious introspection than is good for them, that are most likely to form the tea and coffee habits, and who are most harmed by them, though they find it hard to understand the reason therefor.
Air and Exercise Habits.—Habits with regard to exercise and fresh air are particularly important. In this matter it is only habit that can be really helpful. To work at high pressure indoors for several days, and then, when one is quite on edge, to take a lot of severe physical exercise is not good. Every human being should go out between meals. I am not one of those who believe much in exercise for exercise's sake—what is needed is fresh air. Our sanatorium patients who sit out-doors all day have fine appetites. The advice to a busy man that he must form the habit of being out between every two meals for from half an hour to an hour would usually evoke a strenuous protest, but all he needs to do is to get up half an hour earlier and walk down to his office, and if he will walk back in the evening he will have plenty of air and exercise between his meals.
Change of Habits.—Patients do not want to change their habits. They come to a doctor to be treated. They want some medicine that will, without further inconvenience, rid them of certain discomforting symptoms. At the beginning, at least, patients resent interference with their habits. They are quite satisfied, and to modify them requires an effort that must be continued for some time. The changing of old habits and the formation of new habits are most important for the ordinary ills to which mankind is prone. Modifications of habit constitute real hygiene and are not mere corrections of symptoms, permitting the habits that have led up to them to go on.
Patients may conclude that it is too much trouble to change their habits. We all know persons who feel that they can not give up their coffee. As to whether or not the modification of a habit is worth the trouble it involves, the patient must be the judge after the case is put properly before him. It is possible that he may learn to endure the inconvenience given him by his symptoms rather than to stand the inconvenience of changing a nicely settled habit, and forming a new one. The reward should be put very plainly before him, however, and besides, the consequences of his habit in the future should be suggested so that he may realize just what it will lead to.
MENTAL HABITS
It is evident from the foregoing that physical habits have much to do with making life easier and saving expenditure of nervous energy, but just this same thing holds good for mental states. With care, a proper habit of mind and of the mental attitude towards difficulties in life, can be so cultivated as to ward off many of the discouragements, and most of the causes of depression that weigh heavily on some people. The natural disposition can not be entirely overcome, but habit, as a second nature, can modify the personality so as to make conditions much better than before.
With this wonderful power in habit, it is too bad that its force for good is not used. It is especially important that its force for evil shall not allowed to dominate human actions so as to make them harder of accomplishment. Many people, who are greatly troubled by the inconveniences and discomforts necessarily associated with human life, worry over it to such a degree as to make themselves sick. The expression I have quoted elsewhere of the old man who said, "I have had many troubles but most of them never happened," is a typical example of what the habit of looking at things from a wrong standpoint means to many people. They are confirmed pessimists. Their one consolation, when a small evil happens to them, is that perhaps this may be sufficient to ward off the greater evil that fate surely has in store.
