Hof began a lifelong quest to see just how far his abilities would take him. In January of 1999 he traveled 100 miles north of the Arctic Circle to run a half-marathon in his bare feet. Three years later, dressed only in a swimsuit, he dove under the ice at the North Pole and earned a Guinness World Record for the longest amount of time swimming under the ice: 80 meters, almost twice the length of an Olympic-sized pool.
When he didn't experience frostbite or hypothermia, the body's usual reactions to extreme cold, his extraordinary ability started to get the attention of doctors who specialize in extreme medicine.
Dr. Ken Kamler, author of “Surviving the Extremes,” has treated dozens of people who tried to climb Mount Everest, and instead nearly died from the frigid temperatures. He couldn't believe it when he got word of a Dutchman making the ascent with no protection other than a pair of shorts.
