time to develop internal strength. The influence of exercise in purifying the blood and in promoting activity in all the internal organs really strengthens the "department of the interior" at the same time that it develops the muscles concerned. Muscular stagnation means organic stagnation, to a very large degree. To be thoroughly alive and to enjoy the possession of unlimited vitality it is necessary to be both muscularly and functionally active. The requirements of Nature, or what are more commonly termed the "laws of Nature," in reference to all these bodily functions must be strictly observed, for it is only under such conditions that life and health can be maintained at their best.

The body may be regarded as a machine. Why not make it a strong machine, and as perfect as possible? Its efficiency means everything. If you had an engine, a motorcycle, a sewing machine or a printing press that was a very poor machine, you would like to exchange it for a better one, would you not? You would even spend large sums of money to secure a better machine to take the place of the poor one. But if your body is imperfect, inefficient, weak, rusty and clogged up with grit, dirt and all the waste products due to the "wear" in the bodily structures, you seem nevertheless entirely satisfied. You go on from day to day and from year to year without thinking of the possibility of getting a better physical equipment. But why not consider the body in the same light as any other machine that is of value to you. Your body is the thing that keeps you alive. If it is a poor instrument, then it is more important that you should get a better one than that you should buy a new engine or new printing-press or new sewing-machine. The only difference is, that it is within your power to get a better body machine by building up the one that you have. You can repair it, you can add to its vitality, you can strengthen the functional system, you can make it more perfect and efficient. You can make it a high-power machine that will be of real value in any undertaking that you may wish to carry out. You can make it strong instead of weak, and you can thus enjoy that superabundant vitality without which life is hardly worth the living.

CHAPTER III: The Proper Bodily Posture

The very great value of maintaining the body in a proper position cannot be too strongly emphasized. Man is the only animal that walks erect. He is the only animal in whom old age brings a forward bending of the spine. The hanging head, which is the attitude of hopelessness, and which is caused to a very large extent by the mental attitude that goes with approaching old age, no doubt does a great deal to quicken physical decline.

Therefore it would be wise to remember the very grave importance of a straight, erect spine. Each day of your life should be to a certain extent a fight for the best that there is in life and a struggle to hold the spine as nearly erect as possible. If you are sitting in a chair, sit up straight, head back, chin in. If you are walking or standing, the same rule should apply. The more nearly you can assume the position which is sometimes criticized by the sarcastic statement that "He looks as though he had swallowed a poker," the more nearly you will approximate the ideal position.

As will be shown in the succeeding chapter, it is not necessary to make extraordinary efforts to hold the shoulders back or to arch the chest. The one idea-chin in, down and backward-will accomplish all that is needed. The chest and shoulders will naturally take care of themselves.

Furthermore, it is well to remember that this attitude in itself has a tremendous influence upon both the physical and mental organism. The mind, for instance, is affected to an extraordinary degree by this position. It quickens the reasoning capacity, helps to clear the brain of "cobwebs" and unquestionably adds to one's courage. The man who is afraid hangs his head. He who is void of fear holds his head erect, "looks the world in the face!" There is no question that if a man without fear were to assume the position of fear, with hanging head and shrinking body, he would quickly find himself stirred by the emotions associated with such a posture. He would soon "get scared!" In fact, the attitude of the body has so much to do with one's mental and emotional state that the question of self-confidence or lack of confidence may often be decided simply by throwing your head up and back and assuming the general bodily posture that goes with confidence. It not only expresses confidence: it also develops confidence. There is a great truth here that psychologists and those who write "character building" books have not sufficiently understood or emphasized. And when you feel discouraged, the best way to overcome the sense of depression is to "brace up" physically. It will help you to "brace up" mentally. Try it.

Then there are the definite physiological results of maintaining an erect spine. The mechanical arrangement of the spine itself is such that if it is held erect the important nerves that radiate to all parts of the body from this central "bureau" are able more perfectly to perform their functions. Where there is pressure on these nerves there is bound to be imperfect functioning. The affected organ will work lazily, indifferently. In fact, the entire science of the osteopaths and chiropractors is based almost wholly upon the value of spinal stimulation and the remedying of spinal defects.

There is another way in which an erect carriage has a direct physical influence, namely, in maintaining the proper position of the vital organs. When the body is held erect the chest is full, round and somewhat expanded, affording plenty of room for the heart and lungs. This, in itself, is conducive to vitality as compared with the flat- chested attitude. The stomach, liver, spleen, pancreas and intestines all tend to drop or sag below their normal position when the body bends forward. In maintaining an erect position all these organs are drawn upward and held in their natural position, and this means greater vigor and better functioning on the part of each. This particular consideration is of special importance in the case of women. It all goes to show the truly wonderful value of maintaining the spine in a properly erect attitude.

The sitting position usually assumed is far from what it should be in order to insure health. As a rule, we sit humped forward, with a decided bend in the spine, ultimately developing splendid examples of what we call round shoulders. The spine, while sitting, should be held as nearly straight as possible. The position of the head, to a very large extent, determines the general posture of the body. As nearly as possible the chin should be held inward, downward and backward. I will admit that this position is almost impossible when one is using the ordinary type of chair.

An extraordinary effort is required to sit properly in the conventional chair. Furniture of this sort should be made to fit the body in the same way as our clothing does. The back of a chair should be made to fit the backs of those who are to occupy the chair. The chair-back should, at least to a reasonable extent, approximate the normal shape of the spine. If the chair, throughout its entire back, cannot be thus shaped, then it should be cut off even with the waist line of the occupant. Such a low-back chair will usually allow one to sit erect without serious discomfort.

There has been much criticism of American men on the ground that they are inclined to sit down on the small of the back. They slide forward in the chair, with the back bent over and the shoulders humped forward. But the fault really lies with the construction of the chair. The back of a chair does not fit the human back, and the seat is not at the right angle to rest the body.

Why is it that men commonly like to tilt a chair backward on the
