> I also discovered that human memory is weird as heck. When I walk my mind is somehow mapping my physical location in the world to the content, down to the sentence. If I rewind an audio book I can fairly often remember where exactly I heard a particular sentence. The precise street corner or park trail I was on, to like a 10 feet precision. I do not otherwise have strong memory. WTF brain.

Same experience here. I bike to a big street crossing and I remember suddenly what the hero was doing 1 year ago when I was there the last time :)

And it's split depending on weather and whether I'm walking or biking :) It's especially weird when I'm listening to some book or podcast where travel happens - like Critical Role for example. I now have nearest 50 km around my city mapped onto a D&D world by accident :)
