The audiobook thing! Yes! I hike or mountain bike with books, too, and when I bike those routes now, sometimes I get almost total word recall of a moment in a book I heard years ago. It’s a great sensation.

I recently signed up on goodreads and went and rated a bunch of books I have read to improve the suggestions. It's been fun using the app, as I keep recalling books I've read and they bring up fond memories. My girlfriend was impressed that I could remember what month and year I read books even over a decade ago. But as I saw the title and cover I could recall where I was when I read it. Many were on airplanes so I associated them with the trips and those were some of the easiest to recall.

This happens when the podcast is paused and then next day when rewinded 10 secs and played back, exactly the location flashes in memory,really weird.
