No man chronically neglects any one of the above rules without reducing
his industrial efficiency. No man chronically neglects all of them
without becoming, sooner or later, a health bankrupt.

should become habitual:

1. 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

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. While trying to improve group

one, of eating less next day, of sleeping longer next night, of
being particularly careful to have plenty of outdoor air.

4. Visits to the dentist twice a year at least, and whenever a

anything seems to be wrong with the teeth.

5. Periodic physical examination by a physician.

6. Examination by a competent physician whenever any disorder
cannot be satisfactorily explained by violation of the daily
routine or by interruption of business or domestic routine.
