Yeah, I would NOT want to try to live through that week.
Meanwhile… Bilan….Pure iron and pure calcium are not only single elements, they’re metals.To at least some degree, thermally and electrically conductive, malleable, ductile, fusible, with specific melting points.
They’re also both so unstable they’re rarely found in nature.
Rocks, by definition, ARE naturally occurring, usually aggregates, and they do NOT have those metallic properties.And if it’s man made it’s not a rock.
Iron in nature is usually bonded with oxygen (rust) or aggregated with other minerals (hematite and other iron ores) ..indeed, rocks… but we don’t eat them.
Calcium is overwhelmingly found as calcium carbonate… which makes up marble, eggshells, clamshells, talcum, and Tums©. Some of those are rocks.
We do eat Tums© and calcium supplements…. but they’re man made… most people don’t eat naturally occurring aggregates (rocks) of calcium.
However… I wonder if there are any crystals of sugar occurring in nature? They might be another rock some humans eat.(the usual “rock sugar” is man made.)
