Some people just prefer to listen. I read well and I read quite quickly -- I don't know how many books I've physically read, but it's gotta be in the high hundreds at least -- but over the past ~10 years I've switched primarily to audiobooks. Rather than being something that I enjoy while I'm doing something else, I typically do something mindless with my hands (weave chainmail, cross stitch, sew) in order to give my full attention to the book.
