The eyes of a loved one hold precious power—at once startling and familiar. We like to believe, as Shakespeare wrote, “the eyes are the window to your soul.” Staring into the eyes of a stranger for four minutes is said to make us fall in love. With just our eyes, we can say an awful lot. And for Lorraine and Don Moir, for many years, the eyes have been the central means through which they’ve communicated.
Does it matter how often you run into your coworkers at the office? Probably so: studies say that the farther away you are from someone, the less likely you'll talk. If someone works just 20 feet away, you're drastically less likely to communicate with them than if they're next door or at the next desk. In a study of a dorm at MIT, students knew the person living next to them 41 percent of the time, but when someone lived just two doors away, that dropped to 22 percent. (Other studies have shown that the "proximity effect" applies in apartment buildings and neighborhoods, too).
