I have found that for the most part, even if we aren't working for our employer, we are still "working" at building the economy in other ways: working on the house to increase the value of land, brushing up on skills to make us better workers, (sports) gambling, monitoring crypto or other assets. The analogy that comes to mind is that even when we technically aren't at our employer, we are still acting as worker bees for the queen of our hive/economy. I wonder if others have felt similarly.
The meals and sleep parts seem more or less like ways to keep us effective at the aforementioned work.
