Last week I wrote about the coffee going cold. Eight posts, two longform pieces, nine images — scheduled in one sitting. One person, one dog, one conversation. I called it an exoskeleton, and I meant it warmly.
This week I want to write the other half of that sentence.
Because here is what nobody tells you about an exoskeleton. The machine doesn’t rest. It doesn’t get tired. It doesn’t lose the thread.
You do.
When you put on a piece of equipment that lets you work at three times your previous speed, what you are actually doing is compressing three days of cognitive load into one. The machine doesn’t feel that. You do. And most of us don’t have the wiring for it.
I’m learning this the slow way.
Two kinds of attention
Stephen and Rachel Kaplan spent decades working out why humans break down in environments that demand constant focus. Their Attention Restoration Theory, proposed in 1989, distinguishes between two kinds of attention.
Directed attention is the effortful kind you use at a screen. It filters, focuses, suppresses distraction. And it depletes.
Soft fascination is what nature does to you. The gentle noticing that happens when you watch a branch move or a dog sniff a patch of grass. It replenishes.
Marc Berman tested this at the University of Michigan in 2008. Participants completed a demanding memory task, then took a 50-minute walk. Half through an arboretum, half through downtown Ann Arbor. Nature walkers improved their working memory scores by roughly 20%. City walkers showed no improvement. The effect held even in Chicago winter. You don’t have to enjoy the walk for it to work. Just be in nature, and the brain does the rest.
Meta-analyses since then have landed on a rough threshold: around 120 minutes of nature exposure per week is where the cognitive benefits consolidate. Two hours. That is it.
Two hours a week is the price of staying human at a screen.
Where the work gets metabolised
But here is the research I find even more interesting. Nature walks appear to shift the brain into a Default Mode Network-dominant state. That’s the mode associated with mind-wandering, memory consolidation, and insight. Which means the walk isn’t rest from the work.
It’s where the work gets metabolised.
The connections I can’t force at my desk arrive on their own, somewhere between the third tree and the fourth. The committee, Fimme and Sien and I call them. They’re not giving me ideas. They’re giving my brain permission to do the work it can’t do while I’m looking at it.
I don’t think I’d have understood any of this if I weren’t running an AI-amplified workflow. When your output ceiling was bounded by how fast you could type, the asymmetry between work and rest was smaller. Now the ceiling is somewhere I can’t see, and the only thing between me and burning out is whether I remember to be a person.
Fimme and Sien do not care that I can build a whole quarter’s worth of automations before breakfast. What they want is to smell a specific tree. To notice a bird. In the most literal sense, they are uninterested in the exoskeleton.
That uninterest is the most useful feedback I get all day.
The tell
The honest description of this moment is that it’s thrilling, and it’s disorienting, and the two feelings are the same feeling. The research says two hours a week. My dogs say it’s not optional. I am starting to believe they are both right.
The exoskeleton makes you fast. The walk makes you legible to yourself.
Tomorrow morning, same path. The committee will still be there. The coffee will go cold again. And somewhere between the third tree and the fourth, the work I couldn’t finish at the desk will finish itself.
That’s the tell.

PASS IT ON.
