man that is one messed up situation! ive seen a story on tv a few years back where a person got stuck inside a small hole in a cave and his body is almost vertically-upside down, it must have been an excrutiating experience since our body is not designed to be in an upside-down position as there wont be blood flowing into our heart that way. the guy died eventually as rescuers cant get him out of the hole as he's too far down the hole to be extracted.
