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.
