There is no reason why any human being should die before eighty at least. With proper care the century mark should be reached in the majority of cases. This may sound like an extravagant assertion, but it is absolutely true. It all depends upon taking care of the human machine. Ask an engineer how long a locomotive would last if drawn at express speed every day, or if left standing idly on a siding! He will tell you that overwork or disuse are fatal to mechanism, so far as its capacity for lasting is concerned. Well, the most finished product of man’s handiwork in machinery cannot begin to compare with that wonderful, complex piece of mechanism—the human body; and if care will prolong the life of the lifeless machine, the veriest dullard cannot fail to perceive that the same rule applies with ten-fold force to the human organism, which possesses within itself the power of recuperation—a living machine, every atom of which is being daily replaced as fast as the friction of life disintegrates it. If the locomotive were capable of being reproduced in like manner—of having the daily waste of substance replaced during rest by proper attention to its needs—do you think its owners would ever allow it to wear or rust out? Would they not bend every energy to prolong its existence indefinitely? Most assuredly they would. And is the body, the earthly habitation of the real man, of less importance to himself than the creations of his own hands? Common sense says, “No!” But daily experience shows us that the bulk of humanity are far less careful of the earthly husk that shelters the divine ego than of the machinery that ministers to their wants. We repeat, there is no reason why man should not live to be a hundred, or even more, if only proper care be exercised. The hurry of modern life is fatal to the expectation of longevity, so also is over-indulgence in the pleasures of the table, which is one of the besetting sins of the present generation. If from childhood the care of the human body was made the subject of constant instruction, the second generation from now would see such a marked change in the personnel of the race as would astound even the most sanguine. What if a few less dollars were piled on each other? Which is the more to be desired, a perfect, healthful physique, or a full purse?

To preserve the body in health is an easy matter, if the individual will only bring the same thoughtful intelligence to bear on the subject that he does on the ordinary affairs of life. The natural agencies for the preservation of health are, as previously stated, Pure Water, Sunlight, Fresh Air, Diet and Exercise. The first three are furnished “without money and without price” by the all-wise mother, while the two last simply require a slight exertion of will power, tempered with intelligence.

Of the quintette of agencies mentioned above, water is one of the most important. Water is the original source of all animal life. From it the earliest species were evolved, and by the natural law of correlation, it continues to be one of the most important factors in sustaining existence. Water enters more largely into the composition of all organic substance than the majority of people dream of, and this is notably true of the human body. Few people realize that seventy per cent. of their earthly tenement consists of the fluid in which they perform their ablutions, yet such is the fact.

This important physiological truth should be carefully laid to heart, for it accentuates the vital necessity of imbibing a sufficient quantity of fluid daily to preserve the proportion in the system requisite for health. Water is the only known substance that possesses the power of permeating every cell and fibre of the living organism, without creating disturbance or irritation. Water is, in fact, an indispensable necessity for physical existence—its excess or deficit creating abnormal conditions; but the latter is the more common condition. Being universally present in all the tissues of the body, water is the principal agent in the elimination of waste material from the body, according to Nature’s plan—hence, for the preservation of health, every adult should drink from two to three quarts of water per day, certainly not less than two quarts. One of the remedial factors in the copious use of water in “flushing the colon” is that a liberal percentage of it is absorbed through the walls of the colon, directly into the circulation, thus increasing the amount in the tissues, and causing more fluid to pass through the kidneys—cleansing them.

Hot water is, in reality, a “natural scavenger,” but its virtues are only imperfectly known. As a therapeutic agent it is almost without a peer, and yet it is so little used that it is practically a dead letter. Chemists are burning the midnight oil in their laboratories searching for new weapons with which to fight sepsis, while hot, boiled water, which is one of the best antiseptics in existence, is almost ignored. It may be asked why (if it is such an invaluable remedial agent) it is not more extensively used and advocated? In the first place, its merits are not generally known. In the second place, physicians who know of its value hesitate to prescribe it, for the reason that the majority of patients expect the doctor to prescribe drugs, and are disappointed if he does not. There is a tendency on the part of the majority of people to slight that which is near at hand and easily obtained, in favor of those things which are designated by mysterious titles, or are difficult of attainment. Man has been so long accustomed to regard with a species of awe the hieroglyphics on orthodox prescriptions, that he finds it difficult to dissociate from it the idea of talismanic power.

But to return to its uses. Hot water used as a stomach bath (see description in the appendix at end of book) is a valuable auxiliary in the preservation and restoration of health.
