You don’t live 2400 hours at a stretch with your roommate with zero breaks or outtimes, bro. I doubt you can even live with your SO that long without going out once. Even those in jail get to go out of the room every day.
IIRC there is a popular folk tale about this. A king was exasperated with his princess who got down bad for some peasant, so he locked both of them together in a room for a month and when they came out both of them had nothing but abject hatred towards each other.
I would have 0 problem with living like this, it’s called “ignore each other” lol
