Matt Ridley writes great books. What makes them great is the abundance of information he presents to justify his conclusions as well as his willingness to admit when a conclusion is mere speculation. For anyone interested in evolutionary biology, this is a great book. Two thumbs up (though he does not focus on why only apes have opposable thumbs).
Wow! This was quite a listen! Sex positions and advice were incredible and insightful but a lot of the rest of the book is about ancient practices some of which which seem very strange today - even a bit absurd - like how to get your wife..or one of them..to help you seduce another woman!
I must say, though, that ancient time certainly did not have the puritanical attitude and guilt about sex many have today. They LOVED it and went after it full bore! Kind of refreshing. I agree with another reviewer that the narrator was just right for this kind of book.
