Wim Hof, of the Netherlands, stands up to his neck in ice for an hour and twelve minutes, Saturday, Jan. 26, 2008, outside the Rubin Museum of Art in New York, during a successful attempt to break his previous world record for immersion in an outdoor ice bath. Known as 'The Iceman,' Mr. Hof controls his body temperature by the tantric practice of tumo and is the only non-Tibetan in the world to have mastered this art.
