This book is intended for special forces soldiers. And precisely because of the specifics of their service, the main emphasis in it is on the ability to achieve the deepest relaxation, on complete liberation from the fear of death and on the ability to masterfully anesthetize the consequences of any physical injury. This book is not a textbook on medicine. Any person trying to implement recommendations given in this book, you are personally responsible for the results of your experiments. One of the best books of this kind.
