" A little knowledge—which is what you may call ignorance—is, in fact, a dangerous thing. Almost everyone, at least in the industrialized world, knows that drinking water from a filthy pond or polluted lake can cause life-threatening diarrhea. Yet, relatively few people realize that holding on to resentment, anger, and fear, avoiding exposure to the sun, not getting enough sleep, or eating junk foods, chemical additives, and artificial sweeteners is no less dangerous than drinking polluted water; these habits of life may just take a little longer to kill a person than tiny amoeba do.
