What I do feel, is indignant.
Indignant that I suddenly got to 50, and the world is insisting on telling me I'm now on the downward slope. My body is supposedly going to start falling apart, my brain failing. I'll have less energy. I'll need to exercise more just to keep my weight stable because my metabolism is going to have a strop. Just when I feel more like a woman again, now that the kids are officially adults, my body is going to make feeling sexy much more difficult, with gravity affecting skin, boobs, you name it....
