Saving "Just a Little More" for Tomorrow Morning

This episode looks at something familiar but rarely named: the way curiosity, not work, is often what keeps us awake.

It traces a pattern — an AI conversation raises a new question, an overseas glasses brand leads to another, a news story about space opens into the technology behind it — and how each thread feels less like distraction than research, which makes it harder to stop.

There's a reference to a UC Berkeley study in which people kept awake for around 35 hours showed roughly 60% greater amygdala reactivity to disturbing images, alongside weakened coordination with the prefrontal cortex. The study involved significant deprivation, but it reframes what "just a little tired tomorrow" might actually mean.

The practical idea that emerges is simple: decide when to stop before things get interesting, not after. An AI conversation doesn't have a closing time — it responds as long as you ask — so the end has to be chosen deliberately. One suggested way out is asking the AI to summarize what you now know and what you still don't, then closing the window.

A quiet reflection on the difference between giving up on curiosity and simply handing it to tomorrow — and the idea that going to sleep is how you keep a version of yourself around who can still enjoy the things that interest you.
