Sugar pills, injections of nothing — studies show that, more often than you’d expect, placebos really work. At TEDMED, magician Eric Mead does a trick to prove that, even when you know something’s not real, you can still react as powerfully as if it is. (Warning: This talk is not suitable for viewers who are disturbed by needles or blood.) (Recorded at TEDMED, October 2009 in San Diego, CA. Duration: 9:06)

THE sun slipped below a jagged horizon of red pines, and another long winters night began in the north woods. I sat on a cot in my long johns, a few feet from a wood stove blasting heat like a furnace, inside a canvas tent pitched here about 15 miles from the nearest road in southern Ontario.
On the blue tin plate in my lap lay a lake-trout filet that was all I had to show from six hours of fishing through a hole cut in two feet of ice. The temperature outside was zero, our warmest night yet by a good 10 degrees.
