The human skeleton is pretty tough. If you drink a lot of milk and get plenty of sunshine, your bones can grow to be stronger than concrete; shattering a bone requires a really, really strong hit, as in "crashing your car at 60 km/h"-strong. Did you know that crematoria actually grind bones because otherwise the fragments could be too big to fit in the urns? Also occurs in fantasy settings. This might be part of why people are Made of Iron. Also, compare Made of Plasticine; here, everything but the skeleton appears to be. See also Robotic Reveal. Examples of Stripped to the Bone include:
