Menopause causes the ovaries to decline in function. Hormones diminish, and this includes estrogen, progestin, and testosterone. Since a woman's body is complex, there are a multitude of symptoms that can result.
I have noticed, for example, that a postmenopausal woman can be talking to me at night, and indeed let's make that a ~ cool ~ night with a breeze. Her upper lip and forehead are covered with sweat. In fact, her upper eyebrows and neck glisten in the moonlight. I ask (during our conversation on menopause), "Do you get hot flashes?"
I wait, patiently.
"Well, I guess that it just doesn't feel good," she says.
