Footnotes
The body is affected by what it does (exercise, work, sleep), by things taken into it (food, air, drugs), and by things outside of it (the house in which one lives, climate, etc.). That phase of hygiene which has for its object the making of the surroundings of the body healthful is known as sanitation.
