I think I was born a reader. I was never read to as a child (neither parent read books) and there was never any books in the house, so I had to make do and read anything I could get my hands on. Magazines, anything I could find when we went visiting, I was reading newspapers at age 4. For some reason I was never given books as a child, maybe they just didn't understand.
One thing I do remember is my first trip to a library at about 8 years old I felt like I had gone to heaven and I haven't taken my nose out of a book since (except to change to an ereader but that doesn't count).
I agree that readers are a minority. I have never met anyone who reads as much as I do,which is a pity really, because sometimes people make me feel guilty about sitting and reading while they are doing physical things.
