White Hair

Today my manager and co-worker pointed out that I had a white hair growing out of my head. It should have been simply amusing, as it reflects a frustration we've all had at work. However, I have become slightly disturbed by it. I was just reading the other day that getting gray hairs in your 20's is normal, however since I had never seen one I thought I was still fairly safe. Now the tables have turned, can I expect to find a new one each day, how soon until my need to dye my hair will become a necessity to cover up stray grays? I should run out immediately and purchase myself some eye cream and a pricey anti-wrinkle cream, lest this single gray hair is a sign of an accelerating aging process the likes of which have not been seen since Dorian's portrait, wouldn't that be a tragedy.
