...cancer doctors, since it was the first study to show that a drug can lower the risk of fractures in men with prostate cancer. So far, most trials of osteoporosis treatments have focused on postmenopausal women, who are at high risk of bone loss with the sudden drop in estrogen that occurs after menopause...

Why Her?, Fisher posits that there are four broad temperament types--"explorer," "builder," "director" and "negotiator." Each of these types is expressive of a different neurochemical system: dopamine and norepinephrine; serotonin; testosterone; and estrogen.

"This study isn't an indictment of hormone use at menopause," says Berek. "It just means that like all medicines, hormones have their benefits and risks, so they have to be used very judiciously and for a short time...
