I looked in the mirror this morning after working through the night, and guess what I saw? A few noticeable gray strands caught my eye. A sudden wave of sorrow hit me as I wondered if I have aged this much already. Have you ever been startled by a sudden increase in gray hair after pulling an all-nighter or having an intensely stressful day?
