Books
Because I had to spend so much time in the gym at first, I began to listen to recorded books there to pass the time. Soon I had rules about this art form:
1) Technical books that benefit from charts and graphs, or that you might secretly skim here or there, like Guns, Germs and Steel, are not good recorded books. 2) Most authors are not good as narrators, and should hand over their books to actors to read. 3) An exception is John le Carré, who narrates in a deep sexy cadence.
