A recent study found wearing a necktie could reduce blood flow to the brain.
Researchers in Germany compared MRI results with a group of men wearing a necktie to those not wearing one.
They found that the ties squeezed arteries in the neck, resulting in seven percent decreased blood flow to the brain.
Researchers said that could be dangerous for those with high blood pressure.
