Re-read the thread and your posts. While you did not use the word "stupid", you made things and your opinion of him quite clear.
He did not agree with your anatomical description of the reaction of shock, so be it. Instead of the long and varied descriptions of the major and minor pecs, you could have pointed out that there are ligaments and blood vessels that would play a major part in the tight feelings one feels when shocked, that do run across the middle of the chest. And for your information, the middle of the chest does not have any muscle going across it. The pecs are down either side over the rib cage. That was all he wanted to know.
