Another reason to ditch the tie … According to a new study, wearing a tie is bad for your health. The study, published in the journal Neuroradiology, found that wearing a tie significantly limits the blood flow to the brain by constricting veins in the neck and subsequently hindering the ability to think. Not only that, but it can be extremely dangerous for anyone suffering from high blood pressure, because wearing a tie can cut off circulation by as much as 7.5 percent. Back in 2003 a separate study even found that wearing a tight necktie can increase the chances of developing glaucoma and blindness. (Tech Times)
