A new study in Italy found that DENTISTS can sense when you’re afraid just from the odor you give off. To make it worse, they might make more mistakes because of it. Researchers had dental students work on mannequins that were either in a normal t-shirt or a shirt someone wore during a really stressful exam. When they worked on a mannequin that was in a stress shirt, they made SIGNIFICANTLY more mistakes that could have damaged a patient’s teeth. It is figured that the sweat smell subconsciously made the dental students nervous, almost suggesting that stress might be contagious in some way.(Photo: Little Shop of Horrors)
