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.
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
Yeah but those cells still have proteins making new parts.

Human neurogenesis is far from making our brain a ship of theseus.

But do the molecules and atoms in each cell stay the same?
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
