As a consequence of the absence of athletics and its diverting interest, the German is apt to have learned more than his English colleague, but a {200} comparison of mortality and morbidity tables would show that his resistive vitality, his power to overcome disease and recover from accident is not lower than that of his colleague from across the North Sea. The German is less strong muscularly, and in a contest of physical effort would as a rule come out second best, but then we have gotten beyond the period when it is important for a man to be able to defend himself by physical force, except in emergencies that may never come. Surely the English time and effort devoted to athletics is not justified by this. _Preparation for a Sedentary Life_.--Certainly if a young man is going to live a sedentary life in his after years, it does not seem advisable for him deliberately to devote much time to muscular exercise during his growing years. This only provides him with a set of muscles for which he has no use. Ordinarily it is assumed that muscles are organs for the single purpose of evolving energy. This is not true, since they are important organs for the disposition of certain food materials and for the manufacture of heat for the body. Nature in her economy probably never makes an organ for one function alone, but usually arranges so that each set of organs accomplishes two or three functions, thus saving space and utilizing nutrition to the full. The man with a well-developed muscular system, which he is not using, will have to feed it, and besides will have constantly to exert a controlling power over the heat that it manufactures whenever it is not dissipated by actual exercise. For these reasons he will be constantly nagged by it into taking more exercise than his occupation in life demands, and if he does not do this, his developed musculature is likely to deteriorate so as to be a serious impediment, or to degenerate by fatty metamorphosis into a lower order of tissue that is a clog and not a help to life.
