"Drenching the stomach with it just before, or during a hearty meal, plays the mischief with the digestions, and in most cases with the personal comfort. And yet it is a common practice.... The drink we recommend, and not too much of that, is water only. By a proper choice of food, much thirst may always be avoided.... As to the appetite for ice-water, for instance, in the hot weather, it is an artificial one; simple cool water, and not too cool, is much more wholesome."
Advice on what to drink, from the newly discovered writings of Walt Whitman, "Manly Health and Training, With Off-Hand Hints Toward Their Conditions."
