So the body is our house, and our individuality permeates every part of it. Those who look at our bodily dwelling can gain a very good idea of what we are. The external appearance will indicate to a great extent our character. We glance at one man and say, "He is gross, sensual, cruel, domineering;" at another and say, "He is intellectual, spiritual, fine-grained, benevolent." So we judge of entire strangers, and usually find the character largely corresponds to our judgment, if, later, we come to know the person. The anatomist and microscopist who penetrates into the secrets of his bodily house after the inhabitant has moved out can tell much of his habits, his thoughts, his capacities and powers by the traces of himself which he has left on the insensate walls of his dwelling. The care of the body, then, adds to our value, because it gives us a better instrument, a better medium of expression. The old saying, "A workman is known by his tools," is equally true of the body. The carpenter who cares for his saws, chisels and planes, who keeps them sharp and free from rust, will be able to do better work than the one who carelessly allows them to become nicked, broken, handleless or rusted. The finer the work which one does, the greater the care he must take of the instruments with which he works. A jack-knife will do to whittle a pine stick, but the carver of intricate designs must have his various sharp tools with which to make the delicate lines and tracings. When we speak of health and physical conditions in discussing the question of your value, we are discussing the instrument upon whose integrity depends your ability to demonstrate your value. Many young people think it nonsense to pay attention to the preservation of health. I have heard them say, "O, I don't want to be so fussy! It will do for old folks to be coddling themselves, but I want a good time. I'd rather die ten years sooner and have some fun while I do live." I wonder what these same young people would think if they should hear a workman say, "Well, I have here a fine kit of tools; I am assured that if they are destroyed they will never be replaced; but now, while I am learning my trade, I don't want to be 'so fussy' about keeping them in order. It will do for 'boss workmen' to take care of everything so constantly, but now I want to break stones with these delicate hammers, to cut nails with these razor-bladed knives, to crack nuts with these slender pincers. By and by, when I am older, I'll use them as they should be used, but I think it's all nonsense to be so careful now." If in later years you should hear him complain that he had nothing to work with, would you feel like pitying him?
