In a ghastly job I used to have, every day I had to skim hundreds of pages of text—medical records and complex regulations—every day. I became quite good at pulling out the bits I needed and ignoring the rest. However, I noticed that it made it harder to read fiction in my off hours because I tended to skim at high speed instead of paying close attention. After I left that job, my ability to enjoy good fiction improved noticeably after a couple of months. I think research going on about what reading does to the brain is quite interesting.
