That thought occurred to me as I was looking, for a possible review, at a book coming out later this year. The first sign that something was wrong was when I was 15 pages into it and I still really had no idea of what it was about. (I knew it was about some aspect of modern warfare, but no indication of what this book was bringing to the party.)
Benjamin Franklin nailed it when he said, "Fatigue is the best pillow." True story, Benny. There's nothing like pushing your body so far past exhaustion that you'd willingly, even longingly, take a nap on a concrete slab.
