In recent years, this quiet, peaceful condition, with eyes closed, thorough relaxation and absolute attention, has sometimes been spoken of as the hypnoidal state. If it be recalled that hypnos in Greek means sleep, and that this is a state resembling sleep with the restfulness that sleep gives, the term is valuable in its suggestions. If, however, the word is connected with hypnotism, then there may be an unfortunate connotation. This state is entirely free from the dangers of hypnotism, and instead of making a patient dependent on his physician, teaches him to depend on his own will. It is not a new invention as this term hypnoidal might seem to indicate, but is as old as our history at least. CHAPTER II EXERCISE In recent years a great change has come over the popular mind regarding exercise, especially in the open air. It is well to emphasize at the very beginning the subject of too much exercise, because there is no doubt in the minds of many who study the question, that many Americans, and indeed people of the northern nations generally, take a certain amount of voluntary {199} exercise that is not good for them, though they take it at the cost of considerable effort and sacrifice of time and are firmly persuaded that it is of great benefit. Sufficient Exercise.--There is a much larger number of persons who do not take sufficient exercise. The amount to be taken is eminently an individual matter. Neurotic patients exaggerate everything in either direction, so that perhaps the state of affairs that exists is not so surprising as it might otherwise seem. Instead of the uncertainty that prompts now to too much exercise, and again to too little, for health's sake there must, as far as possible, be a definite settlement of the needs.
