Hard bones can be boiled to make a good sustaining broth and the remains can become interesting jewellery, paperweights, ancient artefacts.

Or guitar nuts and saddles. If I ever need a hip replacement, I'm gonna make sure they give me the removed parts, and I'll have a good (non-squeamish) luthier use them to upgrade a couple of my instruments.

Then I'll wander off, singing, "I'm Back in the Saddle Again..."

Peter.
