But it is an interesting idea anyway. I’ve seen at least 3 or 4 comments in this sub which assume or reference a limited QI that takes you on the longest route to your natural end of lifespan, until you finally die of old age. But that could more pedantically be called QL (quantum longevity). Please pardon the pretentious lingo! What happens in old age? Do you just keep shifting from deathbed to deathbed, avoiding timelines where you die in three minutes, then one minute, and then every second shifting timelines and staying alive forever, suffering in a death bed for eternity? Age is counted arbitrarily and will likely always be counted arbitrarily. The information that drives our consciousness includes the entire natural history of your brain, which means you are technically 14 billion years old. The only thing that gives me pause about quantum immortality is old age. Maybe we don’t get to experience super old age in this reality. A tentative theory unifying Quantum Immortality, Reincarnation, Dreams, and How to build a soul-transfer machine, similar to aliens technology What happens when you die of old age? Like say you die at 100, you wake up in another timeline and live to 101 but eventually you would have to die permanently right? In this I also solve the question or paradox about dying due to old age. Please excuse me for the haphazard writing style and lack of flow. This is intended to be more of a philosophical or speculations. I apologize in advance for being all over the place, more just a stream of consciousness rather than a properly formatted essay. Prelude: My problem with this idea is the concern of old age, and entropy as a whole. If people live to be infinitely old, then why are there no records of people living even more than 200 Years? There are far more people throughout history who are dead than are currently alive. I’m sorry if I am being unclear or confusing or misunderstanding this. How does death by old age factor into Quantum Immortality? For instance, if you died at age 69 of natural causes, would you keep switching to realities where you keep surviving age related illness to the point where you could live to be 2000? A theory: when you die of old age, you wake up in your bed at a younger age, or in another body. The events of your life are a faint memory that you soon forget as you go on in a different layer of the dream we call life. .
