"The Body: A Guide for Occupants" by Bill Bryson

We are reading The Body by Bryson and are about halfway through.  As is typical, it is excellent.  He discusses the skin first and works his way in.  

A quote:"Run a finger along a dusty shelf, and you are in large part clearing a path through fragments of your former self."

I have read that our sense of touch is one of the finest in the animal kingdom.  As I age, I find that my hands are always telling about the world.

Bryson says I have about 100,00 microbes on my skin in each square centimeter of it.

Amazon software says I have reached the limit of allowable copying from "The Body" but I repeat that it is a good book and you can get a paper copy for $3.07.
