I read a similar book once entitled "What could he be thinking?" or something like that. It was based on research that detailed how men's brains are constructed differently and what impact that has on behavior. It was very enlightening, and a good read at a time when I was doubting MrH's masculinity, etc. It turns out that he is a man's man and I was only focused on the areas in which he was weakest at showing it. After reading all the other examples, I could plainly see that there aint nothin wrong with his masculinity.
Anyway, I was totally fascinated by the book. It didn't delve into the female brain, other than to say this is different than the female brain in the following way: xyz, but one could read between the lines and figure out the differences.
I have never understood the feminist insistence on absolute equality, even in light of obvious differences. I think that it sets the feminist cause back quite a bit, in fact, because it makes the originators look unintelligent.
