You see, what I mean is that you will possess knowledge your parents did not possess. In such a grand position the future men and women――your children――will be started right. And so will you if you heed and absorb what I shall tell you. Big muscles do not necessarily mean strength, but to be strong one must have well developed muscles. Seems an odd statement; doesn’t it? A man may inherit big bones to which are attached big muscles. The fibres of these muscles may be coarse, inelastic and under control of a slow motor――a sluggish nervous system. Just as you may have a big motor car, big frames and running gear, but under-powered. Now remember that all real muscular power originates in the nervous system and brain. If the nervous system and brain are not in perfect condition, the full power of the muscles can never be utilized any more than you can get the full power out of your big car if the cylinders are too small or so weak in construction that you do not dare to run them at full speed. This is one reason why men born with big frames and large muscles are not always the strong men. Frequently these men break down in the prime of life. Also during their active lives they really never get all their power in use. I consider such men unfortunate in that they do not possess the knowledge of their condition, so they neglect in early life the necessary rules and habits which, if heeded would bring them to old age in full possession of their natural strength. The weakling who realizes his failings and knows how to correct and care for them, is more often the strong and healthy man in middle and later life. This fact teaches us one of the great laws of nature; that is that we cannot for a day neglect our body; the born strong man does, he never watches or cleans his big machine――it goes to rust and wears out in parts. These strong men as youths, from the mere fact of having big, hawser-like muscles controlled by a slow-moving force, do not have the incentive to build up active muscles nor the energy to train the nervous mechanism controlling muscular activity. The result is that such a man’s muscles remain coarse fibered, fatty, bulky, and respond slowly to the motor centers of the brain. Moreover, they feel in such perfect health that they are careless about their habits and throw away a lot of energy that the man who is building up strength takes care of――saves for future use and material. A youth who desires to build muscular strength goes about it carefully and slowly. Remember that all staying powers, brain or muscle, must be built up slowly. The tough and hardy oak does not grow like the weak poplar――quickly. Its growth is steady, regular and slow, but in the end it is powerful, long lived and richly reproductive. Make haste slowly is one of the fundamental laws of nature.
