if you ask my girlfriend what she reads, she will tell you in all seriousness chicken soup for the soul and shitty teen girl novels. but at least that's something.
During middle school I had almost no social life, I read so much. I was clocking four to six hours a day reading. I went through all the classics by age twelve -- Robinson Caruso, Swiss Family Robinson, The Mysterious Island (kind of a pattern there, hmm) Kidnapped, On the Back of the North Wind, etc.
By Sixteen I had moved onto Sci Fi and Fantasy. I continued my reading habits, often spending weeks out of my summer vacation doing nothing but laying on my back reading.
At nearly 21 I now read TRF, a SciFi short story magazine I get, and the Sunday Newspaper. It's really sad how life sucks away such enjoyable pastimes.
