The famous British traveler, TV host, and writer Bear Grylls tells how and why the ability to survive at any cost became his profession. Even as a child, he was fascinated by fitness: he trained a lot and relentlessly, climbed mountains, hung on the bar, invented ways to escape from a locked room, went out to sea on a small sailboat, and enjoyed the feeling of danger. Later, growing up, Grylls went through the harsh selection tests for the SAS (British special forces), and after several years of service there, he fulfilled the main dream of his life—climbing Everest. The author describes in detail how he prepared for this event and what difficulties he had to overcome to reach his goals.
