Yawning and Stretching

Yawning and stretching are natural processes.  

What we are doing when we yawn and "stretch" is not stretching in the common use of that word.  It is a contraction of some muscles even more than it is a stretching of others.  And that is why there is another name for it - and that is "Pandiculation".  

When we yawn and stretch, it would be more clear to say that we yawn and pandiculate!  

We have learned that social politeness generally frowns against yawning and pandiculating in public so we have generally come to do that far less often that our bodies would be optimal with.  

WE NEED MORE YAWNING AND PANDICULATING!  : )
