I do find that interesting, however, there is something that people who view this do not take into consideration often times. The thoracic cavity is not homogenous like gelatin blocks are. There exists many "partitions", as it were, and lots of empty/dead space. Energy is not distributed nearly as efficiently through the thoracic cavity as it is through a gelatin block.
