A quarter of Americans did not read a book in 2013, study finds
A new study by the Pew Research Center found that in 2013, almost a quarter of Americans

did not read a book. And this included e-books and audiobooks.
I wondered how bad it is over here, in Germany. Well, not much better, actually. According to a study by statista.de (in German), it was around fifteen percent in 2013.
As a general advice for life, I would recommend picking up a book from time to time.
