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?
People that can actually approximately calculate it probably won’t do it. But, as far as I know, then the smaller amount of atoms we take in a sample group of your body, the higher possibility that they were a part of someone’s else body. Thus saying, 1 or 2 random atoms of your body certainly were someone’s organ before. And if we will consider absolutely any creature that could have a specified organ, then the probability rises even more.
