Gray Hair?

I found my first gray hair on my head the other day. I thought it was the way the light was hitting it but upon further investigation I found it to lack color. Seeing as how my hair is long there is much more of it to see. I don't see it as a big deal, it's only one, hell my sister is only 27 and she already keeps her hair dyed to hide gray. I ain't gonna be like that. I left it there because I don't care and for the chance to make it think it is getting away with something. I will get rid of it at some point I am sure, when I annoys me enough. Could be stress related, not that stress ever really gets to me. My trip to the hospital might have done it, I'm not sure. Whenever I find hairs that are another color they have already performed their metamorphasis. I have never found a hair mid-molt. Hopefully when it does go gray it is cool and not like some person who has muscle spasms decided to paint a picture on my head.
