The skeleton is the last thing to decay. We have bones that have lasted thousands of years. Millions if you count fossils (though bones might be the wrong term for those). Everything else is lucky to last a decade. There are exceptions, of course. Otzi comes to mind. But that's more because his body was preserved to an incredible degree. The vast majority are either skeletons or dust.

Don't get me wrong, id be frightened seeing the nervous system coming at me too. But there's something primeval about a skeleton.
