Yawning: the great mystery of life! Why is it that when we hear a yawn, see a yawn, or even think about yawning, we yawn?!
This video challenges you to get through the entire thing without yawning. I tried my best to hold out… I felt them coming on every few seconds and held them back. That was until the chimp got me 40 seconds in. Now, I can't stop yawning! Seriously, I think I've yawned 10 times since watching this. I can't even write yawn without yawning. Ok, that's it!
