Sport, because of the diversion of mind involved, is an ideal form of exercise. An exercise that becomes a mere routine and that can be eventually gone through with so mechanically as to leave abundant room for thoughts of business or study or worries of other kinds, loses sight of one of the principal purposes of exercise as nature demands it.
Horseback Biding.—It is because of the complete diversion of mind that is necessarily involved in it, that horseback riding makes such a magnificent exercise for the busy man. The old expression "the outside of a horse is the [{205}] best thing for the inside of a man" is founded even more on the mental influence of horseback riding than its physical quality. The same amount of exercise in the open air, taken otherwise, often does not accomplish so much good, because a man's thoughts may continue to run on his business or be occupied with his worries, or he may not be able to divert his thoughts from himself and his digestion or his ills. A horseback rider must pay attention to the other animal, rather than himself, and that represents the complete diversion of mind so necessary for the health of most people. Just as soon as man rides an old favorite animal on whose back he can throw down the reins, allowing it to saunter on as it will, while he occupies himself with other things, then horseback riding loses its efficacy and falls back into the class of bicycle riding or carriage riding or walking in the open air unless there is diversion of mind in the scenes, or the necessity for care at street crossings, to banish preoccupation of mind. Unless business troubles and worries are necessarily excluded by its conditions, or are deliberately eliminated from the mind during the course of any exercise, it may even become a renewed source of worrisome thoughts, rather than a renewal of energy, mental and physical.
It is doubtful whether horseback riding should ever be recommended for those who have not been accustomed to it from their youth. To ask a man past forty to learn to ride horseback for the sake of exercise is nearly always a mistake. It becomes a trial rather than a recreation, and may thus do harm rather than good. On the other hand, horseback riding is one of the things that may be, and indeed often is, much abused. The old English fox-hunting squire would never have lived out his life even as long as he did, consuming the amount of proteid material that was his custom, and drinking his three or more quarts of port at dinner every day, but that the excessive drain upon his system by long days of hard riding in the hunting field made calls upon his nutrition which kept even this amount of food and stimulant from doing immediate harm. Just as soon, however, as long spells of severe exercise become excuses for the consumption of big dinners, and exercise is used as a factor to enable one to overeat with more comfort than would otherwise be the case, a vicious circle is formed, and one serious abuse is counterbalanced by another. What many well-to-do people of leisure need is not so much more exercise as less eating.
Walking.—Perhaps the best and most readily available form of exercise for most people is walking. It has one disadvantage. As soon as the walk becomes too much of a routine, and the ground gone over has lost its interest, or is even of such a nature as to permit or, indeed, tempt introspection and occupation with other things, rather than with the surroundings, then walking loses most of its efficacy as a form of exercise. Walking in the country, for instance, becomes monotonous, though at first it is a great source of pleasure. Walking in a large city, however, has little of this objection and as large city life has grown more and more strenuous in recent years, the good effect of walking to and from the office or walking in the busy parts of the city has been increased. Between the trolley and the automobile, and the hustling commercial traffic of the streets, it is impossible for a man to walk through the busier portions of any large American city without keeping his wits thoroughly intent on what he is doing, nor without requiring all of his [{206}] attention for his transportation. An abstracted man will in the course of a half hour have so many narrow escapes from being run down in a busy quarter that he will either eschew walking in that particular neighborhood, or give up his habits of mental abstraction, or else he will come to himself some day in a hospital.
Besides, the passing show in city life is itself of surpassing interest. It is not things but men that interest us most. There are so many phases of human life to be seen on busy city streets, so many things happen in the course of even a short walk to bring out prominently traits of human nature that, if a man is at all sympathetic, he finds much to occupy his attention, to distract him from his own worries and take him away from his business cares. The long walk to and from the office may thus become an efficacious source of thoughts that are different and of profound pleasure. All depends on the man and his mood. Men who try it whole-heartedly soon find a renewed interest in life. An hour of daily walking in the open air with the distractions of city life all around, provided the walking is done briskly and faithfully, is of infinitely more hygienic value than an hour of gymnasium work. There is only one thing that hampers this form of exercise—there are so many excuses to tempt one not to keep it up. If one gets to a gymnasium there is an instructor or director who keeps tabs on one's hours and so helps a weak human will, and excuses are easier made to one's self than to others.
Massage as Exercise.—This curious tendency of men to take their exercise far more regularly, provided some other is concerned in their taking it so that it cannot be neglected without explanation, is illustrated in many of the experiences of the doctor in modern life. A number of forms of massage have come into vogue as wonderful cure-alls. It is comparatively easy for some men, and above all for many women, to take their exercise by means of massage rather than in some more vigorous way that requires their own initiative. A man who is working hard, and who feels the need of exercise, will not take the easy natural way of getting up half an hour earlier, having his breakfast half an hour sooner and then walking down to his office four or five miles, but he hears of someone who gives vigorous massage and he engages him to come every morning and exercise him for half an hour or an hour. In order to do so, he has to get up an hour earlier, but the fact that he has the engagement with someone else, rather than with himself, makes it more difficult for him to make excuses, and so morning after morning, in spite of the fact that he may have been up late the night before, perhaps to a big dinner, he gets up to be given his exercise. If he is a heavy eater he will, of course, at the end of a week or ten days feel ever so much better for he has been using up material that was clogging his circulation and irritating his nervous system.
At the end of a month he will probably feel so much better that he will conclude that he has found the root of all evil in life, or of all disease, in a failure of circulation that can be removed by means of massage, manipulation and passive movements. When he gets well enough to give it up, he drops straight back into his old troubles, because what he needs is a radical change of life that will adapt his eating to the amount of exercise that he takes, and his exercise to the amount that he eats. If this fails to come, he has had only a temporary benefit that has probably tempted him rather to increase [{207}] the amount that he eats normally than otherwise and will probably do him harm in the end. This massage brings about a distinct reduction in the weight of women, and as most of them are very desirous of this, the remedy becomes even more precious to them than to men. Here, too, however, it is only a temporary expedient. They are tempted to eat more than before, or at least not to reduce their diet, and the good that is accomplished is only for the moment, while no habits, either of restraint of eating, or of more exercise in the open air which so many of them need, have been formed.
Passive Movements.—The success of osteopathy has been largely founded on this curious peculiarity of human nature. People are not satisfied to regulate their eating and exercise in a sensible way. They prefer to submit to various methods of exercise, manipulations and passive movements which make up for the muscular exertion that should help the circulation within the body, but do not accomplish the purpose nearly so well as the voluntary exercise of muscles. It requires little exercise of will to submit to this treatment, while for many people it requires considerable exertion of will power to exercise their muscles for themselves. The old particularly, who are likely to suffer from achy conditions around joints, always worse on rainy days, which would be expelled by enough exercise to stimulate the circulation in these structures, find the new remedial measures of vicarious exercise of great service to them and consequently osteopathy has gained many votaries. Old members of many a state legislature who have been accustomed to ride for so long that exercise is almost an unknown quantity in their lives, are treated by the osteopath and lose so many vague pains and aches and discomforts of various kinds that it has not been difficult to persuade them that it is a great new discovery in medicine, and so in many of the states the osteopaths have secured legal recognition.
Summary.—Exercise, as exercise, often does harm rather than good. Thin people seldom need exercise, stout people seldom take enough of it. No one should be encouraged to exercise merely that he may be able to use up material that he has eaten, when it is evident that he is eating more than is required for his ordinary occupation. The question can never be settled without taking into consideration all these individual peculiarities of each case. Properly used, exercise is one of the most important therapeutic aids. But it is liable to as many abuses as are drugs, and the patient's attitude of mind toward any particular exercise is always an extremely important factor. If the exercise produces fatigue and disgust, then it will do no good, in spite of all that is hoped from it. If it creates true diversion of mind, it will surely be precious, even though it may, for other reasons, seem unsuitable.
