Burn up to 6000 calories per day without even moving

Extreme pressure and excessive thinking can increase breathing rate, blood pressure, and muscle contractions. World chess championship of 1984 was called off because defending champion Anatoly Karpov lost 22 pounds during the tournament.

Antarctic expedition made scientists' brains smaller, study finds
