  • Haha, loved the vid :-) Fun fact for you: Higher primates (and apparently dogs) yawn contagiously. Nearly every other species on the planet yawns spontainiously (even fish and reptiles!), the notable exception is the giraffe! I'm a bit of a yawning geek, it's a great fun subject to learn about :)

  • Thats not true actually, yawning is nothing to do with respiration. Truth is nobody knows why we yawn, the best guess so far is that it is a brain cooling mechanism :)

  • its all to do with the vibes :D
