One of the classic characters bred by american culture of the past century and a half is the health fanantic, the man who (in Twain's phraseology) eats what he doesn't want, drinks what he doesn't like, and does what he'd druther not, all the while smugly announcing himself to be energetic, joyful, and certain of long life, and exorting his errant neighbour to reform.
- Samuel Clemens, Following the Equator, two vols. New York, 1906, 2:151.
