The five best doctors anywhere,
And no one can deny it,
Are doctors sunshine, water, air,
Exercise, and diet.
These five will gladly you attend,
If only you are willing;
Your mind they'll cheer, your ills they'll mend,
And charge you not one shilling.
O.S. Hoffman, from Poems That Touch The Heart (1941, 1956)
