I have three siblings. Of the four of us, I have two degrees (B.A. and B.Ed), one of my sisters has a degree, and my other two siblings have high school diplomas. So 2 of us have university degrees, two have high school diplomas - we're all equally rabid readers.
My husband has two degrees (also B.A. and B.Ed) and he reads, but I wouldn't call him an avid reader. He's been reading more now that he has an eReader, but if I weren't such a horrible influence he'd probably be doing something else.
