Feeding time!

Sometimes I wonder what I actually do when I sleep, because when I woke up just now I felt my intestines falling into place. Maybe it was just gravity telling them that "you'd better get down here!" - I wouldn't put that as impossible. Of course that would mean that my bed is a no-gravity-zone, but I'm fairly sure that I don't float in the air when I lie down on it so I don't think that's it either. I'll get back to you on this.
