indigestion which everywhere prevail among themselves. Some of the most incorrigible workers, with both brain and muscle, known to me, take but _one meal a day_,[42] and this because they found the change necessary in order to enable them to perform their arduous labors and preserve their health. Others similarly situated divide this meal into _two halves_——taking a small meal morning and night, or, better than the latter, a lunch in the morning, and at night, after ample rest, the principal meal. No person ever tried this plan and found any need of a change because of lack of nourishment.[43] I mention this last point to meet the stock objection of people who essay to escape from the logic of the position——the necessity for the modification of their own dietetic habits——behind the old dogma, ‘one’s meat is another’s poison.’ (See p. 43.) It is entirely probable that a robust man (a frail one would succumb to the exposure, with or without food) exposed for days together, and for the entire twenty-four hours, to the extreme cold of winter, exercising vigorously meantime, could eat three full meals a day and escape digestive disorder. The habit of approximating as nearly as possible to this diet, in a temperate climate, or while the bodily warmth is maintained by artificial heat, originates the greater proportion of our ailments; while lack of exercise, and the folly of attempting to oxygenate this excessive quantity of food with air that is breathed over and over again——a process which one writer likens to eating one’s own fœces——amply accounts for the balance.
