5 Weird Involuntary Human Behaviors Explained
Our body leaves a lot to autopilot, which is a good thing. Imagine having to walk through your day actively remembering not to pee your pants. That would be totally lame.

Find out what science has to say about these weird behaviors in this week’s It’s Okay To Be Smart! No yawning while watching.
