These beings are doubly fortunate; for they have escaped not only their particular malady, but another not less dangerous to their own well-being and that of those around them――a morbid valetudinarianism, a perpetual fussiness about their own ills and ails. The victims of this complaint are the _malades imaginaires_, constantly coddling themselves, thinking of no one but themselves, of whom we meet an endless number in the wealthier classes of society. It must have been of such as these that old Dr. Johnson blurted out his rough judgment,――“Every sick man is a scoundrel!” They usually forfeit more than they win by such selfish concentration. It is a symptom of disease to think constantly about one’s health. The most effectual remedy for it is to think about increasing the comfort of others. There is no need for me to go into details of what such a training should be to protect one as much as possible against the development of hereditary diseases. The precepts must be adapted to the particular case and circumstances, and in this age Personal Hygiene is a science by itself, with abundant and competent instructors. Its scope is not limited to the prevention of disease, but extends to the strengthening and symmetrical development of the whole body. No one who intelligently pursues his happiness will omit the study and practice of its precepts. Health is not indispensable to happiness. Fortunately, no one condition is indispensable. But there is no other condition which so generally and potently contributes to it. Therefore, he who intelligently seeks enjoyment will pay early and frequent attention to athletic culture; he will seek some healthful and agreeable physical exercise; his posture will be erect and his breathing full; his periods of effort will be prolonged to positive fatigue, and will be judiciously alternated by others of changed activity or complete repose. The trainer of athletes lays down for his pupils a rigid discipline. He is as far from encouraging overstrain and excessive exercise as he is indolence. He condemns stimulants and narcotics beyond a most moderate use; and he is solicitous about such things as sleep, and food, and cleanliness. If his pupils find it repays them to submit to his stringent dicta for the hope of winning a champion’s belt or a silver medal, is it not worth while to accept the much less severe regimen necessary to obtain the Olympian garland woven of the joys which a sound and elastic health offers?
