You, all of you, take in visual information more easily and completely than you do audio alone. It's just how you're wired.

I have found only one audio book I enjoyed -- a book I had already read and loved. And, I read along as it was narrated. Most of the time, audiobook narrators read far too slowly for me. (The book was Among the Living, by Jordan Castillo Price, book 1 of a paranormal gay detective series.)
