we were discussing the parsha at the table, and my cousin was re-enacting how Chushim ben Dan knocked off Eisav's head with a stick and it rolled into Mearat Hamachpaila. that was when someone commented how some of the parshiot are bloodbaths. sister2 pointed out that the stories from Navi can be even more gruesome, as the Jewish kings were constantly fighting battles for land.
"they always got stabbed in the same spot" she commented "right below the fifth rib"
"well that's the spot that closest to the heart" my dad said. he looked at me "right, Miss Nursing Student?" (whenever we discuss anything anatomy or medical related, my parents look to me for confirmation. definitely keeps me on my toes!)
so i explained about the PMI for listening to the apical pulse being in the fifth intercostal space at the mid-clavicular line. but then i recalled how sometimes it takes me a good minute or two to find the right spot to listen to the heart. i wonder how warriors in battle were able to find it in an instant. maybe they had soldiers who were designated to run ahead and grab the enemies, hold them down and feel under their armor for the ribs, count to the fifth, and mark it with a Sharpie, so the advancing army would know exactly where to shoot.
