I had a year or so where I commuted on the train in Boston. I started reading non-fiction, because, well... no matter how boring the book was it was better than staring at people on the train.
I read the biography of Gandi and Elenore Roosevelt, books on the history of Stonewall, 'Conduct Unbecoming" , Some history and art history books... it was well worth the effort.

Trying to find more time to read these days...
