noun: non-informative text used to keep the pathways clean in the mind.

i read children's books. i also read the shampoo bottle when i'm in the shower, the cereal box at the breakfast table, and just about anything else you put in front of me. i think it promotes good mental hygeine. if you keep reading, or so the theory goes, nothing will ever have time to become too firmly wedged in a part of your mind in which it doesn't belong. this doesn't mean it's all in one ear and out the other; in fact, i find that i'm more likely to generate associations and memory flags if i keep the data flowing.
