"Check it out!"
This isn't scientific inquiry. Here is an accomplished neuroscientist's attempts at writing a romance novel/pop psych classic. The behavior patterns and explanations--and the patient/client stories that support these explanations--are presented very generically. Although some women don't necessarily follow Brizendine's biological timeline--some start on the career track before moving into motherhood (or even adolescence) later in their lives--the author seems successful in cataloguing all the general behaviors and explanations for the reader's easy referencing. One even gets more comfortable with the scientific jargon as one reads along.
All in all, I like this book and will definitely refer to it in reference to understanding the women in my life. But note however: both audiobooks for the Female and Male Brains books are unabridged, yet it takes the author 7 hours to read the Female and only 4 to read the Male. Comedy? You make the call.
