I reckon this, like many others I've thumbed through till the wee hours of the morning quelling an otherwise insomniatic episode, is a good place to begin the adventure. At least in the notion that it gets the mind to thinking, and maybe consider the matters relevent to solving problems not normally encountered in the everyday experience. I wouldn't consider any of them the end all, be all for survival knowledge. It's like learning how to ice skate from just reading a book. You get some idea of the theory, but until you actually get to the application and find out what it really takes in guts and reasoning capacity, it is just trivia.
