Today's interesting fact has to do with ties and high blood pressure.

Recently medical research has confirmed that wearing a part of the traditional western formal business attire can contribute to a serious health risk.

A tie increases pressure in two ways.

1) It places pressure on the glands of the neck that help the body control blood pressure and cause an increase in that way.

2) It constricts the blood vessels of the neck and the restriction this causes creates a feed back to the heart which then raises the blood pressure to get the correct amount of blood into the brain.

Both of these have been shown by the increase of pressure within the eye.

There is evidence that it can also cause Glaucoma.
