Bear Grylls spent three years with the British Special Air Service (21 SAS). During this time he suffered a free-fall parachuting accident in Africa where he broke his back in three places. After months and months of rehabilitation, focusing always on his childhood dream of Everest, he slowly became strong enough to attempt the ultimate ascent of the worlds highest peak. Bear has a natural talent for communication and his speaking and TV show (which include Ultimate Survival and Man Vs. Wild) have brought him worldwide acclaim. He is among the youngest and most successful speakers in the world.
