I'm 53 and happy to be here. Starting to grey, but prefer to refer to it as "highlights" in my hair. I too still wonder where the years have gone. No kids, so can't tell the passing of time by their growing up. I read somewhere that life is like a roll of toilet paper...the closer you get to the end, the faster it goes. I'm trying to take more time to savor the days now, as they do seem to fly by.
I'll be married to the same wonderful man 28 years on Valentine's day. awwww, how sweet, huh? We figured this way we'd always remember our anniversary! LOL
