I'm on a plane to Brussels, and I can't sleep. It is supposed to be night, but my body doesn't believe it. So I'm sitting, half watching the in-flight movie (Tron, but this is the second time through). A few rows ahead of me, a man pulls a small book out of his pocket. Without looking at it, he opens to a random page and points. He starts reading from where his finger landed. Sitting there, I wonder: what is the likelihood that he would read the first or last page of his book? I've gotta get some sleep.
