It’s an option, but it’s worth noting that you’re not always idling your brain in quite the same way unless you happen to work somewhere were there are no roads to cross, cars and cyclists to dodge, nor other pedestrians to navigate around.

I sometimes find toilet breaks or coffee breaks (waiting for kettle to boil) fill the “daydream debugging” requirement. But that depends on having a clean bathroom with enough stalls, or an empty kitchen without other people making drinks.

Working from home definitely helps here. Though significantly less so during the holidays when kids are off.

Edit: just in case there’s any misunderstanding, I’m not suggesting having the kids around is a bad thing. I love my kids. Just that they have an obvious impact to my concentration.
