Bathing less frequently than once a week is almost as dangerous to health as it is to attractiveness. 2. Distaste for unclean linen or undergarments and for acts or foods that interfere with vitality should become instinctive. 3. Excesses in eating or playing should be automatically corrected the next day and the next. Parties we shall continue to have. It will be some time before reasonable hours and reasonable refreshments will prevail. Meanwhile it is probably better for an individual to sacrifice somewhat his own vitality for the sake of the union, the class, or the church.

Visits to the dentist twice a year at least, and whenever a cavity appears, even if only a week after the dentist has failed to find one; whenever the gums begin to recede; and whenever anything seems to be wrong with the teeth. 5. Periodic physical examination by a physician.
