Interesting tidbit from Dr. Oz show yesterday afternoon.
Put a pencil vertically along side your face, lined up with the outer corner of your eye. If you do not have any eyebrow hair on the other side of the pencil (opposite from your eye) it could mean you may possibly have a thyroid problem.
Dr. Oz said that the eyebrow hair of people with thyroid problems starts to fall out from the outer side of the brow.
I though that was interesting!
