less inclined to athletic pursuits involving exercise which compels deep breathing.

The method of breathing recommended for women is absolutely identical with that suggested for men. It is a curious fact that until recent years the world generally, the medical profession included, held the opinion that there is a fundamental difference between men and women in breathing. Observation of the natural breathing of boys and girls would soon prove the absurdity of this opinion. Owing to the universal use of the corset, thoracic breathing, or chest breathing, the result of the artificial constriction of the body at and below the waist line, appeared to be the natural method of breathing for women, whereas diaphragmatic breathing was recognized as proper and natural for men. Only in recent years have medical authorities recognized that this difference was really due only to artificial methods of dress and that natural breathing in women and men is absolutely the same. Recent fashions have permitted the enlargement of the waist line in women, but unfortunately there is still too much constriction of this important part of the body. When the world becomes more truly civilized and our methods of dress are based upon common sense and an intelligent understanding of the physical requirements of the body, we may hope that the dress of women will be such as to permit entire freedom in the matter of breathing, and the easy expansion of the body at the waist line. Some day women will learn the value of suspending skirts, stockings, etc., from the shoulders instead of relying upon the restriction at the waist as a means of support.

If you wish to ascertain more exactly whether or not your breathing is entirely satisfactory, stand up, take a deep breath, and observe not only the expansion in the region of the stomach and abdomen but also at the sides and in the back. If you place the palms of your hands upon the lower ribs in the back, just above the waist line, you should feel the expansion of the body in this part pressing upward through the action of the diaphragm as a deep breath is inhaled. Also by pressing the hands upon the lower ribs at the sides, just above the waist line, you will feel the lateral expansion in this region at the same time that the expansion is noted in the front of the body. You will therefore realize that there should be an expansion of the lower ribs at the back and at the sides along with the expansion in the region of the stomach and abdomen. Of course, when a very full breath is taken there will also be an expansion of the chest following the filling up of the lower part of the lungs.

[CHAPTER IX: Outdoor Life]

Civilized man is an indoor animal. We no longer live in tree-tops nor even in caves, but in houses, and a great many of us spend the larger part of every year in close, ill-ventilated, overheated rooms. From a health viewpoint the cave-dweller would no doubt have the advantage over the average American who follows a sedentary occupation. The steam-heated apartments of our great cities are thoroughly aired only on rare intervals, and consequently those who reside therein often dry up in mind, soul and body along with the furniture.

In order to live in every sense of the word we must become a part of the great outdoors. Outdoor life adds to one's vitality and vigor. It increases one's energies and enthusiasms. You cannot be ambitious or vivacious, you cannot really amount to anything in life, if you are confined to an overheated flat.

If there is any hobby that is worth while it is one that takes us out- of-doors. What the attractive features of your hobby may be, is not of very great importance provided this object is secured. You must be lured away from your stuffy living rooms and encouraged to breathe the fresh, pure air of the open.

There are out-of-door exercises of all sorts which are of great value, but even a seat in a motor car wherein your exercise is confined principally to increased respiration through the pleasure that comes with fast riding, is at least of some value. The health of the nation, as a whole, has been greatly improved by the automobile through its encouragement of the outdoor life. But if you can join with your outdoor life some active exercise which will use all the muscles of the body the benefits will be much greater.

There are various open-air pastimes that can be made unusually vigorous, and so can be highly recommended if one is possessed of ordinary strength. Football is perhaps one of the most strenuous of outdoor games, and is to be especially advised where one has the vitality and endurance which fits him for an exercise of this character. Golf is an example of a milder outdoor pastime that is particularly suited to middle-aged and elderly persons, although young men and women are benefited by it, too. It affords excellent exercise in walking, and the swinging of the golf clubs affords more exercise for the chest, arms and back than is usually supposed. One who is not accustomed to the game will usually find the muscles of the arms, shoulders and chest sore or at least stiff from the unusual exercise when first attempting to play this game.
