As someone who currently sleeps, works, and relaxes in the same room these absolutes you're throwing out come off as hilarious. I've literally always lived in a room with both my bed and my computer, always worked and gamed from my computer, always slept within a couple of meters of my desk chair and computer.

You absolutely can work, relax, and sleep in the same space.

Does that mean I prefer that? Could I gain some meaningful benefits from having more spaces to dedicate to certain tasks? Absolutely. And the moment we tax the ultra-wealthy out of existence and therefore make housing affordable again, I'll make those rooms.

But working from home is not reliant on a square ft/m metric that the home must pass, nor how those spaces are organized or themed. I think saying it does only hurts my ability to stay at home, which is better for the environment, the economy, my productivity, and most importantly my life and mental health.

Our brains are not wired to do such a dramatic difference in mental activity in the same location.

Sounds made up bro.
