This has always pondered my mind at times. I have heard yawning is a sign of lack of oxygen, but how does that effect someone else to yawn at times? Is it merely the power of suggestion? from one brain to another? and there again is another question.

I agree with you that's something to wonder about. But the fact is, considering that lack of oxygen as a reason for yawning is only one guess, science has yet to determine just why we, and all other warm blooded animals yawn to begin with. Personally, I have to do it if I see the dog yawn. Go figure!

There are several theories surrounding this. Some think that when someone yawns near you, the air pressure is changed and therefore makes the person next to them yawn. Some primordial psychologists believe that it is because when a person yawns, they are bearing their teeth, and this sets off a primal urge inside of your brain to bare your teeth as well.
I think this is just another one of those mysteries in life we may never know the answer.

Oh dear, not this question again. You should search Yahoo Answers for similar questions and refer to answers given to those Q's. That'd probably be more helpful.
