        Most of that oxygen has been around I would think, but I guess some atoms would’ve come from recent micrometeorites or whatever.

      I guess, some bacteria might have made it into your body in other ways, but might still be considered part of you in the wider sense…?

          Ah yeah, my comment was caveated as such, because I assumed those bacteria to have mostly gotten there via food. Then again, no idea if any even survive going through the stomach acid…
