A great physician has said, "I know not which is most indispensable for the support of the frame,--food or exercise." But who, in this community, really takes exercise? Even the mechanic commonly confines himself to one set of muscles; the blacksmith acquires strength in his right arm, and the dancing-master in his left leg. But the professional or business man, what muscles has he at all? The tradition, that Phidippides ran from Athens to Sparta, one hundred and twenty miles, in two days, seems to us Americans as mythical as the Golden Fleece. Even to ride sixty miles in a day, to walk thirty, to run five, or to swim one, would cost most men among us a fit of illness, and many their lives. Let any man test his physical condition, we will not say by sawing his own cord of wood, but by an hour in the gymnasium or at cricket, and his enfeebled muscular apparatus will groan with rheumatism for a week. Or let him test the strength of his arms and chest by raising and lowering himself a few times upon a horizontal bar, or hanging by the arms to a rope, and he will probably agree with Galen in pronouncing it _robustum validumque laborem_. Yet so manifestly are these things within the reach of common constitutions, that a few weeks or months of judicious practice will renovate his whole system, and the most vigorous exercise will refresh him like a cold bath.
To a well-regulated frame, mere physical exertion, even for an uninteresting object, is a great enjoyment, which is, of course, enhanced by the excitement of games and sports. To almost every man there is joy in the memory of these things; they are the happiest associations of his boyhood. It does not occur to him, that he also might be as happy as a boy, if he lived more like one. What do most men know of the "wild joys of living," the daily zest and luxury of out-door existence, in which every healthy boy beside them revels?--skating, while the orange sky of sunset dies away over the delicate tracery of gray branches, and the throbbing feet pause in their tingling motion, and the frosty air is filled with the shrill sound of distant steel, the resounding of the ice, and the echoes up the hillsides?--sailing, beating up against a stiff breeze, with the waves thumping under the bow, as if a dozen sea-gods had laid their heads together to resist it?--climbing tall trees, where the higher foliage, closing around, cures the dizziness which began below, and one feels as if he had left a coward beneath and found a hero above?--the joyous hour of crowded life in football or cricket?--the gallant glories of riding, and the jubilee of swimming?
