I also enjoy "this is hard, I'm going to lie in the hammock and think about it for a while"

I do the equivalent at work - go away from the computer and think. Well I'm a contractor / consultant with many home office hours now, but I did the same as an employee. In most cases I leave my phone at the desk because a) it helps me focus (same as leaving the computer behind) and b) it signals that I'm not wasting time, I'm thinking. No one has ever complained.

From photos of some development offices of companies that "get" software, the usefulness of hammock-driven development seems well understood there.

When I used to smoke I had the same thing with going outside to stand in the cold and think.

Also, strangely, I think the "deep breathing" of smoking helped with the cognitive processes. That and the release from the nicotine cravings ofc.

Losing the ability to nap was the single most difficult adjustment I had to make when I went back to an office job after seven years working remote. I didn't take long naps, but the ability to lie down and close my eyes for twenty minutes after lunch every day made a big difference. It was also helpful, when I really needed to get some serious thinking done, to have somewhere I could lay back and shut my eyes and really just focus on the problem for a while. The one and only time I tried this at Microsoft, someone burst into my office in panic when they saw me lying down, afraid I had collapsed from a stroke.
