Why do we yawn?!


Question:

Why do we yawn?


Answers:

I was always under the belief that it was you catching your breath again because as you start to drift into a sleep, you're breathing slows down. This catches that back up since we're actually awake and not sleeping...

But it's funny how addictive a yawn is, I read the question and yawned. x.x;
