Probably music. Maybe the sound of your voice on the telephone.
I don't watch many movies or TV, but I did plow through The Wire in an embarrassingly short time. Now I am poking at Mad Men.
Right now I'm reading The Pesthouse by Jim Crace, but I just started it. I also read The New York Times, New Yorker, and lots of non-fiction, especially science and math books and those weird highly-specific single-subject books like John McPhee's Oranges.
