Dr. Albert Saitz, in the Medical Record, writes that, owing to the atrophic changes of age, not only the weight but the height of the body is diminished, the body as a whole being shorter and lighter, while its individual parts are also lessened in size, with the exception of the heart and kidneys. . . . Changes take place in the skin, rendering it dry and wrinkled, the hair becomes thin and white, the teeth drop out, the body bends. These changes induce a general decrease in vigor; the power of the muscles is lessened; the combustion going on in the body is diminished, as is shown by a decrease in the amount of carbonic acid gas exhaled. The vital capacity of the lungs is decreased, although there is a quickening of the respiratory rhythm. The pulse-rate rises, the secretions are diminished . . . Such, briefly stated, are some of the characteristics of old age.
