Personally, I like grey, white, and silver hair on men and women. I think it stems from respecting and liking people older than me. They have so many stories to tell and have experienced more than I. I have a few grey hairs myself and Don has a full head of silver hair. He'll tell you I gave him every one. I say it's in his genes. ;)
I ride public transit quite a bit and sometimes I notice a pretty young lady giving me a 'look' (must be my handsome features). Nope. Her intent is just to get up and offer a doddering old fart a place to sit.
