Excessive talking, chronic coughing, nervous habits, as continual movement of some part of the body, are all enervating influences. The first two are particularly reprehensible. Many people make and keep themselves sick by incessant talking.

"My feet hurt me, I feel sick all over"--ill-fitting shoes, painful feet, pains in the back, physical pain from shock, injuries, surgical operations, pathological processes, loss of blood, impingements, impairments and malpositions affecting the sympathetic system, and physical irritation, all make heavy demands upon nerve energy. Osteopathy and Chiropractic have been largely responsible for the recognition of the importance of the enervating influence of malpositions; but they have resorted to electricity, manipulations, needless "adjustments" and other stimulating measures, as correctives, and have often produced more enervation by their treatments than was produced by the malpositions.

If there is a leak in a dam and it is not repaired, it continues to grow larger until the existence of the dam is threatened. If there is a leak in the powers of the body and this is not corrected, its powers grow less and less each day until the stability and integrity of the body are threatened. If a man's life-blood is running away he makes an effort to stop the leak. If his nerve force is being leaked away day by day he should also make an effort to stop this leak.
