The purpose of this book is to spread knowledge of Individual Hygiene and thus to promote the aims of the Life Extension Institute. These may be summarized briefly as: (1) to provide the individual and the physician with the latest and best conclusions on individual hygiene; (2) to ascertain the exact and special needs of the individual through periodic health examinations; (3) to induce all persons who are found to be in need of medical attention to visit their physicians.
Dancing combines wholesome exercise, social enjoyment, and the acquirement of skill and grace, but it is seldom of much hygienic value because it is frequently overdone, and often involves bad air and loss of sleep. In one large plant where the employes were examined by the Life Extension Institute, the management regarded the harmful effect of dancing as their chief obstacle to efficiency. Many of the large force of girls and women were accustomed to dance until late in the night, bringing on a condition of chronic fatigue.
Card-playing and similar games afford wholesome mental recreation for some persons. However, they, too, are liable to be associated with late hours, and other disadvantages even when they do not degenerate into gambling. Card-playing, dancing, and many other popular forms of amusement often border on dissipation.
