Original Title: TIL of Guðlaugur Friðþórsson, a fisherman who in 1984 survived 6 hours in 5 °C cold water after his ship sank and then trekked barefoot for 3 hours across lava fields before reaching safety. Despite only wearing shirt, sweater and jeans, he showed almost no symptoms of hypothermia or vasodilatation.
