I started noticing grey hairs in my head when I was 21. By the time I was 30, I had a definite salt and pepper thing happening. I'm not one to dye my hair, so I let nature take its course and hoped for the best.
I'm now 34, and I fully accept and embrace my grey. I've got lots of grey on both sides and a nice patch of white in the top front. Heck, I even have grey in my beard now, and I dig it. I see it as natural highlighting, a feature that practically makes me seem mature and wise.
And besides, I've still got a full head of thick hair. That's the main thing...
I took this pic during an awesome walk through Etienne Brule Park yesterday.
