Your bones are made of calcium, which is also a metal. You've got a metal frame inside your body.
Hate to burst your bubble, but the calcium inside your bones is not in a metallic form but as calciumphosphate. So no metal frame but one made of a salt I guess.
The thing that started this conversation is hemoglobin, which is also not metallic but a protein. I don't think anyone was confused and thought that there's actually shiney silvery elemental metallic calcium in our body.
