A GOOD HOBBY.——On pages 84, 111, and 137 I have barely touched upon this subject. I wish now to call attention to it as a matter worthy of greater consideration than might perhaps be gathered from what has been said. Personally, I begun the practice, when I was about sixteen years old, of taking long, deep breaths occasionally, at odd times during the day, from reading a little slip explaining its usefulness in “strengthening” the lungs, and increasing their capacity. At the age of eighteen, I remember, upon being examined for a life insurance policy, the examining surgeon expressed great surprise at the unusual “swell” or expansion of my chest——about five inches increase when my lungs were fully inflated, over chest-measure when I had forced out as much air as I could conveniently. Upon explaining, that for a number of years I had made a practice of throwing my shoulders back, taking very deep inspirations slowly, holding my breath a moment, and then as slowly “breathing out”——doing this the first thing every morning on rising, and in a sleeping-room which was never close, again on going out, and occasionally during the day,——the doctor said: “A good plan that accounts for it.” In all cases of weak lungs, whether chronic or from “taking cold” (see pp. 40 to 45 for a consideration of the colds delusion), when it is difficult to take a full breath on account of “cramps,” catches, or pain in the lungs, this practice will be found of great value, if persisted in. In many instances it seems impossible to take a long breath——is, indeed, impossible; but a little gain may be made every day, by crowding down “one notch,” so to say, at each trial. Quite a large percentage of all persons will find on trial that there is more or less of tenderness upon first making the attempt, or at one time or another, whenever there is any degree of irritation of the stomach. The patient, or experimenter, should inspire a little, however little, beyond the point which seems all that he can do, and persist in this treatment every day. There can be no doubt but we have here a most important aid in the treatment of consumption, not only, but of all ill-conditions of the physical man. But the deep, full breathing that comes from having exercised vigorously is best of all (see page 84). 2 [NOTE ON BRIGHT’S DISEASE.]
