>>12197663It gets even wilder when you realize that your body's a Ship of Theseus of atoms, constantly shedding and replacing its building blocks. All the atoms that composed your kid self are long gone, and the ones your body is currently made of are much more recent, picked up along the way. Pieces of you from 10 years ago are now in circulation all over the world, spread out in the bodies of inanimate objects, plants, animals, people both older and younger than you etc. just like they were before you came to be. Those childhood memories you hold are from a person you haven't physically been for a long time.
