Researchers are starting to unravel the mystery surrounding one of the most common BEHAVIORS: the yawn. WSJ’s Jonathan Rockoff and evolutionary psychologist Dr. Andrew Gallup explain new studies suggesting it’s a way of keeping your brain sharp. Science has disproved the theory that it’s the body’s way of sending oxygen to your brain when deprived.
