And what should these people do? If there is one good lung left, or a goodly portion of two, there is much which they can do. Before breakfast they need to be more careful than others because of their poorer circulation. Still, in a warm and comfortable room they can work to advantage even then. In most instances consumptives have not large enough chests. Stripped to the waist, there is found to be a flatness of the upper chest, a lack of depth straight through from breastbone to spine; and the girth about the chest itself, and especially at the lower part of it, is often two or more inches less than it is in a well-built person of the same height. Now, to weed out these defects, to swell up and enlarge the chest, and bring it proper breadth, and depth, and fulness, this will go far toward insuring healthy and vigorous lungs. And how is this done? Standing under the handles in an appliance like that represented in Fig. 8, holding the body rigidly erect, the chest out, the knees and elbows unbent, bear the two handles downward on either side of you until the hands are as if extended on a cross, using only very light weights at first. Lower the weights again, then bear down again, and so do ten. Just as you bear down each time, inflate the lungs to their utmost, and hold the air in them until you have lowered the weights again. Rest about a minute, then do ten more, and a little later ten more. This will be enough before breakfast work the first week. At breakfast, and whenever sitting down throughout the day, determine to do two things--to sit far back on your chair, and to sit at all times upright. No matter how many times you forget or fail, even if a thousand, keep trying until the erect posture becomes habitual. This point once reached, you have accomplished a great thing--one which may aid not a little to save your life. Next, about an hour after breakfast, start out for an easy walk. Going quietly at first, the head held, if anything, back of the vertical, and the step short and springy; quicken later into a lively pace, and, holding that as long as you comfortably can, return to your room. If your skin is moist, do not hesitate a minute, but strip at once, and with coarse towels rub your skin till it is thoroughly red all over, and then put on dry under-clothing. If you then feel like taking a nap, take it. When well rested, do thirty more strokes at the pulley-weights. In the afternoon try more walking, or some horseback work if you can get a steed with any dash in him. After you are through, then more weight work. Finally, just before retiring, take another turn at the weights.
