The question "How much are you worth?" is not answered by discussing your bodily conditions, for your body is not yourself. It is your dwelling, but not you. It, however, expresses you.
A man builds a house, and through it expresses himself. The external appearance causes the observer to form an opinion of him, and each apartment bears the impress of his individuality. To look at the house and then to walk through it will tell you much of the man. The outside will tell you whether he is neat, orderly and artistic, or whether he cares nothing for the elements of beauty and neatness. If you go into his parlor, you can judge whether he cares most for show or for comfort. His library will reveal to you the character of his mind, and the dining-room will indicate by its furnishings and its viands whether he loves the pleasures of sense more than health of body. You do not need to see the man to have a pretty clear idea of him.
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?
No "kit of tools" was ever so complete as is the bodily instrument given to each one of us. Its mechanism has been the inspiration of inventors; it combines all forms of mechanical devices; its delicacy, intricacy, completeness and adaptability challenge the admiration of the philosopher, the engineer, the master mechanic.
I cannot here tell you of all its wonders,[1] but I would like to give you such an exalted idea of its importance that you would look upon it with reverence and take a justifiable pride in keeping it in perfect working order. I would like to make you feel your personal responsibility in regard to its condition.
