Many of us will be familiar with the basest form of ringxiety - when one phone rings and everyone in the vicinity suddenly starts checking their pockets or handbags with frantic abandon.
67% of US adults say they've heard their cell phone ring or felt it vibrate when it actually hadn't — a phenomenon experts are now calling "ringxiety."
