when I
read Bob (BYB's) post about his cutting his finger-- i reacted by curling in the finger I had cut--(index in my case) and
"Protecting" it-- I remember the pain-- and I don't want to feel it again

This supports a feeling, or a belief, that I've had for some time that they laws of the physical universe are applicable to our psyches as well. Perhaps this is the basis for psychodrama, art therapy, and other therapies. Comments, please?
