For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some ‘organic element’ since I couldn’t accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.

    From Wikipedia on bones:

    Bone matrix is 90 to 95% composed of elastic collagen fibers, also known as ossein,[5] and the remainder is ground substance.[6] The elasticity of collagen improves fracture resistance.[7] The matrix is hardened by the binding of inorganic mineral salt, calcium phosphate, in a chemical arrangement known as bone mineral, a form of calcium apatite.[9]

    So the statement is a bit faulty, not only because of the relative low amount of calcium in our bones, but also because it appears as a mineral. We distinguish between salts and metals because of their chemical properties being quite different (solubility, reflectiveness, electrical conductivity, maleability and so on).

    Edit: I do realize the point of the comment was not to be entirely factual, so if I am allowed as well I would say science is pretty metal.

      We also distinguish between metals and non-metals by field of study. Ask an astronomer which elements are metals sometime.

      Thanks for the reality injection!

      The statement was glib but even the partial truth of it made me wonder when I first learned it.
