What's the general impact of graying hair on SMV? I'm 28 with a full, dark brown head of hair. By looking at all the men in my family it's obvious I'll never go bald by natural means, but I have a streak of silver running through my bangs and my sides/sideburns are begin to turn silver as well.

I've always seen it as a distinguishing feature, but a recent TRP thread sowed a seed of doubt. My face is lean and clean-shaven and my hair is short and well kept.

tl;dr: salt & pepper - yay or nay?
