@StillwaterRipple,
I had a (legal) revealing experience qua blood chemistry in 1971:
I was (quietly, secretly) mad at someone purportedly, ostensibly
in my mind because of what I deemed a social affront.
After I had an outstanding, very flavorful and satisfying Italian meal,
I felt so dramatically better, that it became conspicuous to me
that I had been irritable from low blood sugar b4 I had the meal,
NOT because of a perceived social blunder against me.
The b4 and after David were in very abruptly stark contrast to one another.
The moral of the story is:
remain well armed and eat plenty of really good Italian food.
