Anything except horror movies, and fluffy teen fodder.
Television is dead.
Anything I can get my hands on. Historical fiction (Bernard Cornwell), Science, History (Sailing the Wine Dark Sea), Nature, Fiction, Cars (especially Ferrari), Religion, Philosophy, Cultural Studies...
Alexander, Leonidas, Nelson, Churchill, Roosevelt. Because they didn't have to ask why, they just knew.
