I’m no scientist by any stretch of the imagination, but I would assume that as we grow more knowledgeable about ourselves and how we are affected by not only what we consume but by what environmental factors do to us physically and psychologically, we find that death by natural causes (as was a common occurence in the generations before) becomes used less often on the coroner’s report. Rather than guess what killed someone, we can use our technology and intellect to decipher the exact cause of death. The term ‘death by natural causes’ always struck me as weird, for what else could there be? Death by supernatural causes? To answer your main question, I would say No, not directly. It all has to do with the level of our technological sophistication.
