From the time I learned reading at school that has been my major hobby. So I'm fairly sure that during my university years, when I wasn't fully-employed and still had my eyesight work perfectly, it must have been more.

Also, there are novellas on this list and a few short stories, but I do think the Ann Somerville and the Moriah Jovan books even that out, hmmm.

I will survive the loss of all the other hobbies, PC/Internet, watching TV, watching movies, whatever, but I'll go bonkers if I should ever be unable to read. The only way out would be audiobooks. Something similar - audio stand-up comedy saved my sanity quite a bit last year, when reading just wasn't doable.
