This is fascinating. Humans don't have to leave earth for long or far before they start to forget what "human" means.

"Every astronaut who spends more than a few months in orbit comes back describing some version of the same disorientation. Rain smells overwhelming. Fabric feels abrasive. Familiar streets feel piloted rather than driven. The Earth their bodies evolved for has become, briefly, a foreign planet their nervous system is re-learning in real time."
