  • That’s actually not true, there are quite a lot of cells in our bodies which are never replaced such as the lenses, cones, and rods in our eyes, egg cells, neurons, the hairs that detect sound in our ears, our heart muscles, among many others. The ones that do get replaced vary greatly in how long that takes or how often it happens.












  • As someone with adhd it’s completely normal for me. When you’re a kid you have good reason to keep track of your age because at that time of your life you change dramatically between ages as you develop as a person, plus it’s important when asserting your identity to other as that too develops. When we’re older it’s just a number that only comes up once a year and is not that much different from the previous number, and so it’s easier to lose track of especially for people who have an affected working memory and time blindness like me. Idk if you have adhd or how often people without adhd experience this sort of thing but I can speak for my own experience. I forget how old I am, and other people’s names, all the damn time lol.

    Multi-track drifting. Also while some infinities are smaller if you’re just counting out an infinite number of individual humans then I’m pretty sure they’re the same size infinities one is just social distancing. Smaller infinities are ones like those in between each part of the bigger infinities. To represent a smaller infinity you’d maybe have to have an infinite number of smaller humans crammed into a spot the size of one of the spaces between the humans on the other track, or something along those lines. The real number track does contain smaller infinities between each integer via infinite decimal points but I don’t think one track would technically be smaller than the other in this case since they run parallel to each other but neither are technically limited in the “length” of their infinity so to speak. But I could be misremembering how they classify smaller infinities.
