Everyone knows the feeling. Someone makes an embarrassing remark about you: your face heats up, your skin turns pink. The phenomenon intrigued even the naturalist Charles Darwin, who saw in it "the most peculiar and most human of all expressions."
The strangest part is that a compliment produces the same effect as mockery. Praised in front of others, you feel the same warmth rise to your cheeks. What exactly is happening under the skin, and why does the body respond the same way to shame and to pleasure?
