      Apart from specific non-proliferating cells, statistically all of your entire body’s cells will have been completely replaced every 7 years*.

      So we’re all exactly like that… just over such a long period of time we don’t notice it.

      *For the quickest proliferating cells in your body, like your skin cells, this is a matter of just weeks.

        iirc nerve cells basically live forever. So I’m the end, you’ll completely regenerate, except for your nerve cells

            And new neurons are being made all the time, just more slowly and in specific places that then migrate to where they’re needed, so as not to disrupt too much of the neural mesh (and thus completely derail memories or other models).

        Some of the atoms/molecules in your body have probably already cycled through the entire food web and come back to you … probably multiple times, especially if you don’t move around a lot and you eat locally produced food.

          Probably not, even in non-proliferating cells. They do still have to repair damage after all.

          But I have no idea of what the timescale is for the complete replacement of every atom in your body

      With consciousness not being fully understood it’s possible you’re a different person every time you wake up or just randomly between thoughts or maybe you’re everyone and you just quickly round robin context switch or maybe you don’t have a consciousness and I’m the only one who has one?

      This is my view: Your body ages and regenerates. You are a living ship of theseus, you are a different person at different stages of life. Yet, you retain the memory of your past life.

      The ship of theseus is an entirely different ship, but it retains the memory of a self.

          People with Alzheimer’s usually are totally different people. Though they do tend to retain some long-term memories or skills.

            People with Alzheimer’s usually are totally different people.

            Are they, though? They certainly aren’t treated as such socially. We don’t start calling them by different names, they remain married to the same partners, they don’t lose ownership of all their stuff, they’re still considered the same person for tax and government benefit purposes…

              That’s just everyone around them not letting go (not saying we should). In the context of memories making us who we are, they’re totally different people.

      I’m taking bids for a contract: what’s the minimum rate of surgeries per year you can offer to make me immortal. I offer a perpetual fraction of my lifetime earnings, to be agreed upon later.

        I can make you immortal with zero surgeries per year! Just sign right here for 20% of your lifetime earnings in perpetuity.

        Sure, sure, I know that sounds like a scam, but don’t worry – it’s guaranteed! If you ever die (thus discovering that you have not, in fact, been made immortal), you’re entitled to a full refund of everything you’ve ever paid into it, plus interest!
