How could gray hairs form on such a young person?

I just turned 18 March 22nd and today I just realized a strand of gray hair. How is this so? I mean, I don't think its a big deal to the point where I go out and buy hair dye. I'm just wondering, is it stress?
I am a Senior with alot on my plate, but I think I hold everything together down well.
And how would this explains about the many gray hairs my male friend and female friend both have compared to my one strand?

I'm 19 and I have a spot of grey. It doesn't bother me. It's actually from a scar when I got hit in the head a long time ago. Maybe that is what yours is coming from too.

Grey’s Anatomy Spinoff Casting – Meet the Girls

After the bit-by-bit revelation of the cast of the upcoming spin-off of Grey ’s Anatomy, two more additions are unveiled. And this time, they come in the form of two womanly figures.

Aside from Grey’s Anatomy’s Kate Walsh, who will obviously lead the series, the controversial spin-off has already confirmed Taye Diggs, Tim Daly, Paul Adelstein and Chris Lowell as cast members. To nearly balance the male dominated squad, the people behind the show have incorporated Amy Brenneman and Merrin Dungey as of March 13, 2007.

The two fresh add-ons to the Grey’s Anatomy spin-off are no novices when it comes to television exposure. In fact, these two are considered veterans, having acquired numerous television and films credentials. Brenneman, a 42-year old Connecticut native, is an actress popularly known for her role as Amy Madison Gray on the serial drama entitled Judging Amy. She also starred on the television series NYPD Blue from 1993 to 1994. This Harvard graduate also appeared in movies like Heat, Casper, Daylight, Fear, Nevada, Your Friend and Neighbors, Things You Can Tell Just by Looking At Her, and Bye Bye, Love to name a few.

As for Merrin Dungey, this 35-year old actress from Sacramento, California, is best known for her portrayal of Francie Calfo on the action-drama series Alias. She is an accomplished ice skater and the youngest recipient of the UCLA Acting Award. Her other credits included All the Time in the World, The King of Queens, Summerland, Malcolm in the Middle, The West Wing, Friends, Living Single, Murphy Brown and Curb Your Enthusiasm.

Now that the Grey’s Anatomy spin-off is gradually uncovering its ensemble, the viewers’ interest and curiosity becomes more and more intense. And although six cast members have already been made public, there is still no word on their character plot or even the title of the much-awaited medical drama.
