In my opinion death is simply explained by the human body not having reached it's final form yet. We are constantly evolving, but evolution has been concentrating on short term survival for a millenia. It's only recently, in evolutionary terms, that long term life has become viable. I would say our healing abilities point to the fact that we are evolving along this path, and that it is also an obtainable goal, just look at the immortal jellyfish.
