"When someone is yawning, do you yawn too?"..
7 May 07
Yawning is the sucking in of oxygen as your brain is lacking oxygen and that is you you yawn in the first place. So if you yawn and suck in an ammount of air that takes away air from another person so they then have to yawn as well. I think it is something like this. I remember having a discussion with my science teacher. But that was like 2 years ago or something.

I have always wondered the reason for that too! I'm not sure why, but it happens to me all the time too. Sometimes when I'm talking to a friend and one of us yawns, we'll just start passing it back and forth and we take turns yawning! lol It's pretty funny, but it starts to get annoying after awhile when you can't get it to stop! haha
