Why Are Yawns Contagious?
Contrary to popular belief it has very little to do with carbon-dioxide or oxygen, but everything with hitherto mysterious mirror neurons that seem to be flow enablers I bet. While their function of inducing copied behaviour has been investigated over a range of human behaviours and activities, including such shared experiences as smiling, body-language and learning, I predict that the proof will be known as soon as the researchers get bored with the testing rest.
If research proves me right it will also provide unequivocal proof that our nature provide for shared enthused actively, and uses the same method to inform our peers of experiences that are not worthy of mutual pursuit.
