All sorts of music, Sci-Fi - Babylon 5, Farscape... Science - I wouldn't study physics otherwise, Reading both fact and fiction for different reasons. I love getting caught up in the narrative of a great book (Eon by Greg Bear is great) but I'm also fascinated by historical books. I love to find out about things whatever they may be.
