There are generalisations for both sexes, and these are scientificlay proven but there will always be exceptions. Having read (actually listened to the audio book) why women cant read maps and men dont listen, a lot more makes sense about myelf as a guy as well as women. Other than the obvious, there are marked differencies between male and female, different hearing (explains the hifi), they have different eye size/sight (why they can find things in cupboards, but we judge spaces in cars better) they have more conections between the left and right hemespheres of the brain (why they can read a book, watch television and hold a phone conversation all at the same time and we cant) This is a very entertaining book and well worth a listen. The little plays acted out in this will make you cringe with ther portayal of arguments you HAVE HAD.
