I crack my fingers way too much. I always feel uncomfortable if I'm not doing anything with my hands, so if I'm standing around talking to somebody, I tend to either crack my fingers or rub my knuckles. Or I'll tap my fingers on a hard surface. If my hands aren't moving, I feel like I'll have a panic attack. I don't know what I'm going to do if my hands ever get eaten by a bear.

Another nervous habit I have is spontaneously lighting fires. Some people call it arson, I call it art.
