  1. So, I woke up today, and yawned. So a question popped into my mind: why do people yawn? I've heard sometimes you yawn because you see others do it, but you know what I mean.. what triggers it?
  2. Go here: http://en.wikipedia.org/wiki/Yawn

    Freaky. Reading that article, I yawned at least four times. Yawned again as I'm typing this edit. My eyes are now officially watering...
  3. I know what you mean. I started yawning when I read this thread. It is definitely contagious!:weird:
