The question is not whether it is a cached tought but whether it is a good thought. And what I claim is that it is both good and extremely difficult to understand precisely because of our natutal bias to avoid death. As for references, I suppose it is a central thought in continental philosophy since Hegel: Heidegger and Jonas but you can find it elsewhere, even as far away from existentialism as Mayr or Maturana.
