Well, it seems that I would fit into this category here very nicely.
I'm twenty-six years old (going on seventy according to some of the kids in chat) and first read
The Hobbit when I was eight. The summer that I was nine, I had chicken pox and couldn't go anywhere for a little bit. I read
Lord of the Rings and
The Silmarillion straight through. Started reading when I woke up and read until I went to sleep, even holding the book in front of me during meals. (I was at my grandmother's house, my mom would never have let me get away with that one.)
Ever since then, every winter, I start with
The Hobbit and work my way through
LotR and the
Sil. I haven't quite gotten up the stamina to read all of
HoME straight though (again - heh heh).
