How does your being sick (or injured) affect your reading? Do you read more? Less? Do you pick out a different book than you had already planned? Do you have a "comfort book" that makes you feel better?
I don't tend to read while I'm sick. My illnesses usually involve weakness or dizziness, so focusing my eyes well enough to read is difficult. When I am sick, TV is my friend.
I do have one story about reading while on bed rest, however. When I was pregnant with my first child, I read The Feast of All Saints by Anne Rice. It is one of her few books that isn't about vampires. It was what book bloggers call a chunkster, but since I was on bed rest I had nothing but time. It wasn't a very good book, but I pushed myself to finish it. I have yet to attempt another Anne Rice book because her name will forever be associated with nausea, cramping, and unsatisfactory endings. I'm not sure that I want to taint another author by reading her books while I'm sick!
