Nicholas Royle has blogged recently about how he gets a lot of his reading done by walking. That’s not audio books + walking, by the way, but actual ambulatory reading: on a pavement, through the lingerie department of Debenhams, going up and down steps and escalators in tube stations, reading.
My response to this is twofold.
a) Are you quite insane Nicholas Royle?! Apart from the cognitive overload, and thus diminishment in attention and returns for both activities, are you not just setting yourself up as Nerd Fodder for louts and ne’er-do-wells to bother? You might as well be wearing a faded Dinosaur Junior t-shirt that has TRIP ME UP/MUG ME printed on the back of it.
