This might be interpreted by some to border on the fringes on pseudo-science, but I feel logic dictates that conclusion must be one of many possibilities according to the theories. Has anyone ever considered that the many worlds interpretation combined with the anthropic principle has some interesting ramifications? It would stand to reason, by many worlds and the anthropic principle, that Schrödinger's cat would exist only in a universe which it can. The cat's conscious experience would likely never be aware of its own death, even though its double is dead in the box. So if our universe is constantly forming new branches, it would stand to reason that a person may have died many times already, but to his own conscious experience, he will continue on in the universe or universes in which he is alive. Once one man of many of his copies is the "last man standing" by consequence of being old to the point of death with no other possibility for an accident; or at a point which all possibilities will lead to death--the man will have traversed as much time in a conscious state as possible. One could also consider quantum eraser experiments and its variations. Particle/waves do not take dead end paths. Quanta exist only where they can and also on paths in which they can continue. It would thus stand to reason that a strong anthropic principle exists by way of quantum behavior--that the anthropic principle is it not merely an illusion, but a natural manifestation of quantum behavior. The natural conclusion could be that if you are reading this and are not a philosophical zombie, that you will never experience an accident unless it is the only possible outcome from this point in time. I may die to you, but it is more likely that I am still alive to me, and vice versa. Conscious experiences may be intersecting with varying wave probabilities or even forming "alive-probable" relationships due to quantum behavior, acting to preserve the probability that you will continue on with the people you know until probability leaves no outcome except separation by death, probably beginning with the person most likely to die to you. If many worlds holds, we will all live for a very long time and the concept of death is misunderstood. We may become separated, but you yourself will live as long as you possibly can, or at the very least, if you are the last man standing, you will perceive nothing other than a very long life. Of course then the question would focus on what differentiates your consciousness from your dead copies. It may not be definite but it is possible by all this that the universe/multiverse preserves conscious observers with more efficacy than we realize. Have you ever fallen from a tree at 20 feet, only to be completely unhurt? Ever skid your way through oncoming traffic to avoid a rear-end collision? Have you ever experienced a seemingly impossible outcome which saved your life? I have.
