yawn.

I saw someone yawning yesterday... I forced myself to look, to watch from start to finish, the contagious yawn. I felt a peculiar sensation in the musculature of my jaw for a good two minutes afterward. A yawn was trying to raise up from deep within... I kept suppressing it, not wanting to yield to the primordial reflexes. I did manage to suppress. But I thought it so peculiar that we are wired this way. What sociologic benefit is there to the reproduction of someone else's yawn? Most things that we do not reason into existence are remnants of evolutionary psychology. Impulses, feelings... they are there because they helped the individuals within a species survive and thrive, yes... natural selection. Yet, I find no potential reason why the contagiousness of a yawn should propogate itself through centuries of humanity.

Anyone have ideas?
