I found this pretty interesting. I do it everyday yet i am unaware of what it truly is.
http://en.wikipedia.org/wiki/Yawn
A yawn is a reflex of simultaneous inhalation of air and stretching of the eardrums, followed by exhalation of breath.
Yawning is associated with tiredness, stress, overwork, lack of stimulation, or boredom. Yawning can also be a powerful non-verbal message with several possible meanings, depending on the circumstances. In humans, yawning has the infectious quality, i.e. seeing a person yawning, or just thinking of yawning, can trigger yawning which is a typical example for positive feedback.[3] The exact causes of yawning are still undetermined.
I can bet you will yawn from reading this link.
