I'm a big fan of the Uncle John's Bathroom Reader series, but this book is a complete miss. It tries for the wry tone of the other readers but just comes out sounding juvenile and often flippant when discussing serious topics - for example, its rather graphic description of how to dismember a human corpse (in a chapter about cannibalism) has a disconcertingly cheery tone, and when the very same tone is used in the next chapter (a discussion of how to create cosmetics in the wild - yeah, I'm going to be concerned about my appearance when I don't know where my next meal is coming from), it's just irritating. I'm actually annoyed that I wasted both money and time on this book. Take my word for it and don't bother. ( )
