The Disappearance of Literary Men Should Worry Everyone

To me the problem with fiction boosters is they claim a lot of benefits to reading, but they rarely back those up with numbers. I'm not saying the numbers don't exist (they probably do) just that I rarely see them mentioned.

Like reading books can be a very time consuming hobby, so it would be useful to know how few books you can get away with reading while still getting the majority of the benefits.
