Since the atoms that make up me are billions of years old, and given the wild cycle of matter in nature, what is the probability that, for example, I contain at least a small percentage of atoms that were once someone’s penis? And if that’s the case, is it possible that at some point all people and all matter on Earth will be 100% made up of atoms that have been penises at least once?


We’re all just borrowing recycled particles for a little while, before making them available for others, in future. Just that man started messing with that traditional equation when he came up with burials, and later coffins.
Not just that, but our living bodies are composed of something like ~50% bacteria and other organisms, and with mites living in our pores, eyelashes, etc. Fun stuff to think about, eh? :D
Wish I could just tap out and pass control over to them for a while, sometimes. “Here, you guys have fun, I’ll see you in 8 hours.”
Fun concept. Related to that, I understand that our gut bacteria have some actual influence on how our brains operate.
