Yeah exactly, why would it?

  I am just adding to your explanation. The brain is insensitive not because it is "inside your skull" but because of the lack of pain receptors in the brain. Our bone marrow is inside our bones. Trust me, it is not pleasant to touch.

    Yeah that's exactly what I was saying. It doesn't need touch receptors because it's inside your skull. It makes sense to evolve pain sensitivity in your bones because if you are doing something which is causing damage inside your bones, you had better have a signal to stop. For most of the evolutionary history of humanity, if your skull was compromised, you would be dead.

      Ah! I understand your point better now. You didn't mean skull enclosure to be the direct reason but something that influenced the lack of pain sensing nerve endings to have a reason to develop there.

        Exactly
