it is a myth that people actually yawn because they are tired though coincidntly you may be tired.The main reason we yawn is because the cells of the body have been starved of oxygen, it may be environmntal at thats why we all join in, especially more so in a indoor environment.

it goes back to the caveman days. when it was time to go to sleep, the Alfa male would yawn to signify the it was time to sleep and it would be passed down through yawns. simple minds are easy to program which Povlow(sp?) discovered.

It's a proven fact that yawning is contagious somehow. Weird how that works, if you ask me.
