Although I'M in my early 40's, I still didn't get grey hair yet. I may find one or two gray hairs once in a while, but not more. Same thing with the beard.
I then thought that if I was to get all grey, how would I react?
Would you try to hide gray hair by coloring your hair, or would you accept getting old and having gray hair?
To me, gray hair means you're getting old. I don't like that getting old feeling.
How did you react when you saw your first gray or white hairs appear?
