In real life, I'm always reading. I make sure to carry a book with me at all times in my pocket, in case I can sneak in a few minutes of reading anywhere. Even if I don't have a book with me, like say in work, I'm reading something. It's just a part of my lifestyle that I gained when I was very young.
I read any genre. Science fiction, fantasy, romance, the classics, current fads (Twilight is actually something I can criticize because I read it, novel concept), nonfiction, text books... The list goes on. The one genre I really don't like are biographies, but I will read them if the person is interesting.
