Silver/grey hair in men

Just wanted to throw this out for discussion: what do you think of men who have silver or grey hair mixed in with their natural color? My boyfriend has long, black hair threaded through with silver strands, and I think it looks incredibly sexy! It makes me wonder why women are in a rush to cover up their silver hairs, because I think the difference is dramatic. As a blonde, I can't wait until my hair turns silver, but, judging from genetics, I have a good twenty+ years before this occurs!--HT
