Get a book of the complete series! It's such an incredible book, at first it's quite slow, but once you get past A Study in Scarlet, and The Sign of Four, your world changes! I'm already seeing the TV show as not as good as it could be...
I only listen to the stuff that interests me. I like pointless facts. And besides that all i need are basic life skills. I like pointless facts. Facts that make people look at you and think: that's amazing, how does she know that?
I like that. And I like things which will spawn a deep conversation or an argument. A civilised argument, of course.
