In all of us oldsters the problem of personal hygiene looms up with new dimensions. In our prime we gave little attention to health. The body responded to most of the demands we made upon it. If we were very tired, we slept the sounder. We paid no attention to minor ailments, which soon righted themselves. We ate or drank what, and as much as, appetite called for; exposed ourselves to wind and weather, heat and cold, wet and dry, with impunity. We could go without sleep a night or two if necessary and feel but little the worse for it; could abuse our eyes, nerves, heart, digestion, muscles, and more or less escape all evil consequences; could work at top speed and with an intensity that rung up all our reserve energies for days or weeks if need be, and could feel sure that our good constitutions would enable us to bear the strain and to more or less promptly recuperate. But now our credit at the bank of health begins to run low. We must husband our resources lest we overdraw them. Overdoing is a veritable bugaboo. There are certain symptoms we must never disregard on pain of days of lessened efficiency. We have had one or more signs of special weaknesses we must heed. There are some things that we must rigorously refrain from eating or doing. There is a weak organ, too, that must be humored. Appetite has perhaps been too keen and must be reined in. We must select the items of our dietary with discretion and self-restraint. A typical respondent says he can still indulge his love of hill-climbing, bicycling, swimming, and even skating, and exercises with diverse gymnastic apparatus that he has had set up in his garage, to say nothing of golf, which he holds to be best of all, and autoing, which has become with him a veritable craze. All these things at the age of seventy-five he still does occasionally but is becoming shy of doing so lest he be thought trying to seem young. He lately stole out alone at twilight to skate, when one urchin called to another, “Hey, Johnnie, doesn’t that old man skate bully?” He said he felt like cuffing him for calling him “old” and hugging him for praise of his performance.
