Very nice pictures indeed.
I'm struck by the fact that your face has changed, even since we met, to reflects your changing person. It has become more defined, and your skin is lovely. As for the hair, I've always loved grey hair (yes I use English spellings...). Silver hair as well, but for me there is something just plain nice and down to earth about it.

Keep up those Zumba sessions, clearly they are really good for you!
