In E.'s case the overexcitable hypokinetic stage lasted until about the ninth year, and then there was a great improvement, though he still was of the same general type. He became a fairly good runner for a short distance, learned to swim, though he stood the cold water poorly, was clever and graceful as a dancer and was quite popular. At sixteen he left school to enter business, because of the straitened means of his family. He entered into adolescent period later and suffered greatly from his sixteenth to nineteenth year from, fatigue, hypochondriacal fears, and had to have a good deal of medical attention at this time. Sex questions perplexed him, for he became quite passionate and at the same time had much moral repugnance to illicit relations. His sexual curiosity was intense, and he read all manner of books on the subject, went to the burlesque shows on the sly and almost became obsessed on sex matters. At this stage he made only a mediocre showing in his business career, though his evident honesty secured him promotion to a clerk's position. After his nineteenth year he seemed to gain again in energy and endurance and was fairly well until his twenty-eighth year, though he had to nurse his endurance at all times, developed very regular habits of sleep, diet, etc., and in this manner got along. Once he had an opportunity to join an organization which would have paid him a better salary, but the hours were irregular, and it would have demanded much exertion and excitement, so he passed it by. In 1917 he joined the army, partly because of patriotic motives, partly because he was convinced that army life might develop his endurance and energy. He was sent to an army post in the South and within two months of his entrance had "broken down." He was sleepless, restless, was irritable and "jumpy," had lost appetite and the feeling of endurance. Life seemed intolerable, though he had no desire to do away with himself, for he had no quarrel with life itself but was disgusted with his inferiority. He was hospitalized, but this did little good and he was afterwards discharged as medically unfit.
