A Walk in the Woods: Shelly Morgan

Bill Bryson hiked the Appalachian Trail, leaving and returning to it. Over the months, he notice a pattern, which he describes in A Walk in the Woods:

"At the end of the first day, you feel mildly, self-consciously, grubby; by the second day, disgustingly so; by the third, you are beyond caring; by the fourth, you have forgotten what it is like not to be like this. Hunger, too, follows a defined pattern. On the first night you're starving for your noodles; on the second night you're starving but wish it wasn't noodles; on the third you don't want the noodles but know you had better eat something; by the fourth you have no appetite at all but just eat because that is what you do at this time of day. I can't explain it, but it's strangely agreeable."
