I propose that there be audiobooks of the ‘just for fun’ kind as well as the learny kind.
I figure its learning rate would be unaffected by reading traits and slower than books and may even affected by current base speed (the basic idea being too high or low a base speed and you arent paying attention because cold/drunk pain/poison/high) sans traits and theyd provide small amounts of morale. Id advocate adding dedicated cds for them and a device to play them out of a car but im sure theyd come in predled form too. maybe usb sticks? make those laptops functional or make unsecured consoles able to interface between usb/mp3
