Working the jaw is tied to memory and thought. So said a New York Times article reporting recent scientific research.
If that’s the case, why do I get my best ideas while showering, or while driving, rather than when eating? Maybe I chew at more times than I know. One of Mom’s aunts worked her jaw constantly, with a small smile. And then she would say something. And then return to silently working her jaw around. Mom spoke ill of this aunt, calling her the family conniver, the trouble-maker. I guess to create her schemes she had a lot of extra thinking to do.
I hope I’m not like her. Mom doesn’t seem to think so, thank goodness,
