Summary
You're probably going to yawn during this episode. Sorry. We'll cover why the old 'more oxygen' explanation didn't survive testing, the brain-cooling theory, and why yawns spread between people, chimps, and sometimes from you to your dog. Why the Hell Is That? is an Origami Penguin Press production.
