One of my greatest pleasures is spontaneous yawning. So fond of a good yawn I have not mastered a surreptitious yawn. I have been known to yawn at inopportune moments. The very act of yawning floods the brain with cool air keeps us alert. A remnant from days inside caves, yawns are also contagious and the very act of yawning can start a chain reaction.
In fact I predict a few of you are possibly yawning at the very thought of yawning. Something to to be happy about. Heres to yawning. A positively wonderful bodily function.
