This has been a longstanding theory of mine. The brain is lazy and doesn't like to think - people sometimes miss manual labor because you don't have to spend too much time thinking since at some point it becomes rote.
The ones in which you fully disconnect are so good for your private life. You leave the office and don't even think about opening the work laptop anymore, that's something special.
Which also makes 'keeping up with evolving tech in your off hours' so frustrating, it's no longer fun.
When I worked in food service, any problem that came up that wasn't solved when my shift ended, would likely still be fixed by the time I worked next.
Compare that to current job- must maintain several projects, all of which are constantly changing scope, while leveraging soft skills and playing office politics, while worrying about career development...
