That's why I prefer to listen to podcasts when taking walks etc, rather than full-on audiobooks - if my mind wanders and I start thinking about something else, it's not a big deal if I missed an episode of some tech podcast. With an audiobook, I have to try and find where my mind left off! (which is usually a lot more cumbersome than when the same thing happens while eye-reading)
Contra argument: this means podcast too. You need total solitude. Most podcast are useless, the only one I found useful (people in podcast just shit talk unlike audio books or/and crafted essays). Econ talk is great one (was recommended on HN) and every other where the guest is smart
