Too little attention is generally given to the preservation of health. It is far better to prevent disease than to know how to treat it when contracted. It is the duty of every person, for his own sake, and for the sake of humanity, to inform himself in regard to the laws of life and conscientiously to obey them. All need to become acquainted with that most wonderful of all organisms, the human body. They should understand the functions of the various organs and the dependence of one upon another for the healthy action of all. They should study the influence of the mind upon the body, and of the body upon the mind, and the laws by which they are governed.

We cannot be too often reminded that health does not depend on chance. It is a result of obedience to law. This is recognized by the contestants in athletic games and trials of strength. These men make the most careful preparation. They submit to thorough training and strict discipline. Every physical habit is carefully regulated. They know that neglect, excess, or carelessness, which weakens or cripples any organ or function of the body, would ensure defeat.

How much more important is such carefulness to ensure success in the conflict of life. It is not mimic battles in which we are engaged. We are waging a warfare upon which hang eternal results. We have unseen enemies to meet. Evil angels are striving for the dominion of every human being. Whatever injures the health, not only lessens physical vigor, but tends to weaken the mental and moral powers. Indulgence in any unhealthful practice makes it more difficult for one to discriminate between right and wrong, and hence more difficult to resist evil. It increases the danger of failure and defeat.
