Daring to Go Gray

I've never been a fan of supermodel Kristin McMenamy.  There was always something about her androgynous eyebrow-less look that I found unappealing.  But now that she has matured to the ancient age of 45, I find her more attractive, especially because she has allowed her hair go gray.
I think that she looks great

I'm not giving up my unruly long blond locks anytime soon, but I do find premature gray hair, especially when it is this long, to be striking.
Opinions?
