You probably felt like yawning when you clicked on this link. If not, you’re probably at least thinking about the fact you’re not thinking about yawning. And if you are susceptible to yawns, the word “yawn” written over and over probably isn’t helping. Yawn, yawn, yawn.
If you’re still suppressing that tingling feeling in your ears and the back of your throat, well done. But now try watching this video by College Humour. Full of yawning. Their sole mission in life is to get you to yawn. Can you make it through?
