the metal hiding in your bones, quietly running on the strength of stars.
means A soft, silvery metallic element (symbol Ca) essential to living things, forming the hard structure of bones, teeth, and shells.
from From Latin 'calx,' meaning 'lime' or 'limestone' — the same root that gives us 'chalk' and 'calculus' (originally a little pebble or limestone counting-stone). Sir Humphry Davy named the element in the early 19th century after isolating it, borrowing 'calx' because lime had been calcium's most familiar disguise for millennia.
