yawning

Turns out that yawning IS contagious.  And, it's your friends that might be the leading cause. lose friends and family are more likely than acquaintances or strangers to catch someone's yawns, a new study finds. The researchers suggest this yawning contagion is, in part, the result of empathy, in which we can attempt to see things from another person's angle and respond to that person's emotions.
