I don't play much anymore. It's hard because I live in an apartment and I don't want to bother the neighbors with my catlike screeching and endless scales. At this point I've let it go for so long that I'll have to relearn where the notes are, and it actually hurts to play -- I never appreciated how much exercise it is. It's why professional violinists have crazy strong arms and good posture. I assume it's probably the same for dancing -- it's all in repetition and muscle memory.

Criminal psychology sounds soooo interesting! What do you plan to do with it? Gonna be an FBI agent? :D
