Dont pull those grey's....two will take it's place. Dont know how true that is but have allways been told that.
Well...being the old-fart that I am, I have plenty of them grey hairs. I dont remember my first grey hair but I would have to say it introduced itself around the age of 25 so about 18 years ago. The grey does not bother me at all, matter of fact I think it add's character.
