I've found a whole slew of things on audibles, and I listen to them when I go walking. It's AWESOME, and increases the amount of data I get to take in when I don't have to actually manually read something. Doing it during exercise hits two birds, one stone. My last read was
Beyond Boundaries. Excellent data, excellent reviews. Im willing to go through my whole audibles account and put together a whole list of brain books they have that were awesome, but I gotta make sure you can really use it. It would be a good amount of work, since Ive already been on there for a couple years and listen often.
