15 minutes alone. It’s a short amount of time, but for many people this lasts forever. Even behind closed doors, it seems like anxiety follows us. Researchers at the University of Virginia conducted an experiment to understand how 18 men and 24 women would behave when left alone in a room for 15 minutes, with nothing to do. Two options were given to them: either rest or else inflict themselves with electric shocks. Twelve men and four women, presumably bored, chose the shocks. One of them even resorted to that punishment 190 times.
