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.
