To be true, I was a bit sceptical when I started reading this book. The author didn't help when he started with examples based on "dating" and its rules, a concept that is extremelly alien to Europeans. He continued with some blatant factual errors, but the more you read, you began to understand that he wasn't totally wrong. In the end, I was a reluctant convert, even if I believe that he treated a number of subjects a bit shallower than was necessary.

All in all, a recommended reading.
