Bear was brought up on a small island off the south coast of England, where his late father taught him to climb and sail.
A martial arts expert, Bear went on to spend three years as a soldier in the British Special Forces (21 SAS). He then suffered a free fall parachuting accident in Africa, and broke his back in three places.
Yet despite this, and after months of military rehabilitation, he went on to become the youngest Briton ever, and one of only an elite number of climbers, to reach the summit of Mount Everest.
Now one of the youngest and most sought-after motivational speakers, he relates his remarkable experiences to audiences and corporations all around the world.
Bear lives with his wife, Shara, and their little son, Jesse, on a Dutch barge in London and on a small, remote Welsh island.
One day he hopes to buy a home that doesn't leak.
