The same is for Deaf people. There are many Deaf people who don't like reading (after all they have to overcome a handicap of reading in an auditory language, this is not impossible but they as children need a different way of teaching), and those Deaf people who are real bookworms.

Of course the bookworms then have an easier access to education in written form (and that's why I am both a Dipl. Ing. FH in IT and a Bachelor of Law).
