I eat very spicy food and I've noticed for a while now I've lost the ability to detect when I'm being burned in my mouth (at all, it's actually a bit of an issue sometimes). The rest of my body is the same as it always was - save for my fingers, which I can use to flip things in hot oil (probably a result of exposure to hot oil). Perhaps you are on to something :)

Chef hands come from calluses and the nerves in your fingers dying a little, I think! It's pretty useful tbh
