At the recommendation of my partner, I read this in one four-hour sitting while on the plane. The book provides an overview of the hormone changes that occur over the lifetime of a woman (spoiler alert, there's quite a few more than for the males). I found it to be quite informative and a great wealth of knowledge to have available, particularly when dealing with the opposite sex.
The stages include: Fetal, Girlhood, Puberty, Sexual Maturity, Pregnancy, Breast Feeding, Child Rearing, Perimenopause, Menopause, Post Menopause. In addition, hormone levels change constantly throughout the menstrual cycle. Overall, I'm pretty sure I'd have a lot of problems with that many hormones changing all the time.
Since I was reading it in printed form, I didn't mark down as many quotes, but here are the few I did:
During times of physical separation, when touching and caressing is impossible, a deep longing, almost a hunger, for the beloved can set in. Some people don't even realize how bonded or in love they are until they feel this tugging at their heartstrings when the beloved is absent. We are used to thinking of this longing as only psychological, but it's actually physical. The brain is virtually in a drug-withdrawal state.
Louise was hurting--literally--from the loss of love. Until recently, we thought that phrases like "hurt feeligns" and "broken heart" were simply poetic. New brain-imaging studies, however, have revealed their accuracy. Rejection, it turns out, actually hurts like physical pain because it triggers the same circuits in the brain.
