Charles Krauthammer: The health-care myths we live by - The Washington Post: "After “first, do no harm,” medicine’s second great motto should be “above all, humility.” Even the tried-and-true may not be true. Take the average adult temperature. Everyone knows it’s 98.6 . Except that when some enterprising researchers actually did the measurements — rather than rely on the original 19th-century German study — they found that it’s actually 98.2.
But if that’s how dicey biological “facts” can be, imagine how much more problematic are the handed-down verities about the workings of our staggeringly complex health-care system."
