That thread got me thinking, too. Society may not think I'm as hot as I was at 20, but I FEEL hotter now. If given the choice, I would not go back to my younger self. I feel stronger than ever, and I think I look better than ever, too.
So, I guess I am still defined by my self image, but that image is finally something I like, not something I want to change. Who would have thought, that the girl who hated her appearance for so many years, would finally be able to feel this way! Yay for getting older!
