the body's living scaffolding, rebuilt entirely while you weren't paying attention
means A bone is one of the hard, calcified structures forming the skeleton of vertebrate animals, supporting the body and protecting its organs.
from From Old English bān, sharing roots with Old Norse bein and German Bein — though oddly, in those Germanic cousins the word came to mean "leg" as much as "bone," a drift you can still hear in the German Bein. Beyond the Germanic family the trail goes cold: there's no firm Indo-European ancestor, making bone one of those plain, ancient words that seem to have always just been.
