Why is "femur" THE go to non-skull bone? Like any writer anywhere is thinking about a bone name to mention in their story and almost everyone goes, uhhhh idk, femur? Why do we just not know any other bone names?
@ArcanePigeon the scapula is my favourite, though admittedly probably mostly because a lot of my musculoskeletal issues occur around it 
@OctaviaConAmore Every human knows a small subset of bones:
Skull
(Any bone they have broken or had other issues with)
Femur
That is all.
