Reasons I've had gray hair since I was 12

(According to other people)
  1. I hit my head as a child
  2. I'm super stressed
    And have been for 10+ years
  3. It's a birthmark
  4. It's where I keep my wisdom
  5. Red hair turns gray more quickly
    I happen to have bits of red hair
  6. My maternal grandmother grayed early in life
    Despite almost all of my traits coming from her, this is a stretch.
  7. The only thing I know for sure: I have gray hair cause I let myself.
