This book appeared as a result of the struggle or agreement of several prerequisites. One of them, and I often heard it, is "To be afraid of wolves - not to go to the forest." There is no need, they say, to catch up with fears. Everything is not as terrible as it is written in books. Another is that climbers, like representatives of other difficult or even extreme sports activities, although they strive for a zone of increased objective dangers, are not at all suicides. And their actions and actions are still carefully calculated. As a rule.
