Speaking of which, one of the distinctive features of bowel movements is slowness. You can't hurry shit. A colon is nearly a full stop: nature intended it that way. It made our biorhythms such that things done in a hurry are usually less valuable and memorable than things done savouringly. The slowness of intestines suggests how we ought to live—unhurriedly, relishing the moment, licking the last lingering drops on a wineglass, using calligraphic pens to write letters and refusing to look at e-mail.
