This book gave me something that no other self protection related book has given before. The missing piece to the jigsaw on our understanding of what makes somebody tough. The secret domain. I will not talk about that here because it would spoil your reading of the book but I can assure you that you will come away gobbsmacked. The author also interviews key figures from Martial arts, boxing, bodyguards, streetfighters, Forien Legion, Territorial Army, Wrestling, Armed forces, Bouncers, Vietnam veterans,and so on to find out how they would make somebody tougher than they are now! The title implies that its a book for 'Guys' but its content is relevant to both sexes. This is a great book that you must check out if you are interested in what makes tough people tough..
