The problem of finding a golden mean between excess and defective diet, exercise, work, and excitement, was almost always present. The fads that individuals stressed were horseback and bicycle riding, hunting, tramping, sleeping out-of-doors on an open porch, developing a programme that kept both mind and body busy all day with objective things, indulging in one or even several avocations often far removed from the main line of interest, etc. Some stressed more or less exact routine, while others found virtue in having none but always following their inner inclination and took pleasure in breaking up old habits. One old man loved skating; another, when he was seventy-three, took up automobiling with great zest. A man of ninety has a rub-down by a nurse every night and morning, with some massage. Another is so dependent upon the food to which he is accustomed that he always takes his cook with him in his private car and even if he goes out to dinner must be served with viands prepared by this particular servitor. Then, after exactly half an hour, he leaves the table, even when he is visiting, for a brief siesta. DeSaverin tells us that old people are liable to develop Epicurean appetites and, as they advance in age, can distinguish liquid and solid viands with far greater acuteness than when they were younger. Our data do not, however, confirm this but suggest that gustatory inclinations grow more amenable to reason. Appetite, we are told, is the safest guide, pointing true as the needle to the pole, to the nutritive needs of the body. It is, nevertheless, very modifiable, and the old often easily come to like the food they have learned is good for them, although they very rarely adopt dietaries suggested for their benefit by nutrition laboratories. It does seem, however, that there should be institutions where old people can go periodically for personal surveys of all their habits and receive suggestions that, based upon their idiosyncrasies, would doubtless be marked by very wide individual variations. It is certain that the diet and regimen most advantageous for the person of one diathesis would be very deleterious to another. _Are you troubled with regrets for things done or not done by or for you?_
