we yawn because of our lack of oxygen

my india pig yawned just a while ago, i was wondering why he done that aswell lol

[Abercrombiespanker]

Real reason, tiredness, get tired you breath less and you yawn to get a big breath of air and it is contagious.

yawning releases electricity in the brain, unwanted, clustered stresses that fire about in our heads and keep us alert and awake. when we yawn our neurotransmitters vibrate and expel all the shit of the day. it slows our breathing down and relaxes us for sleep. well thats what i think! it definelely disposes of something that the body no longer needs. i love yawning and try to do it as much as possible. it feels good and has a positive effect on the body.

Haha, this was interesting. I yawn a lot too, and I guess why I yawn is because of anti depressants I am on, along with anxiety disorder. I always feel like I yawn TOO much and I feel rude, haha. That's good to know though, thanks. (:

yawning is psychological, did i spell it right? anyway, when u see someone or hear someone yawn it makes u yawn too lol.

That was very interesting. I never knew it was associated with certain disorders. I remember one of your earlier videos when you found out about the MS. How is that going?
