A very thorough, informative book. However, a lot of his sources are not true and can be debunked with a quick Google search, e.g. the notion that female faces change shape to be more sexually attractive when fertile, and that female-named hurricanes are deadlier than male-named hurricanes.
Of course, this is not a problem. The sources are there for us to peruse ourselves after all! When reading anything, always remember not to take everything as fact just because someone with credentials presents it in a believable way. ;)
