I like to pace around, when nobody else is around, and quietly talk to myself.
When I stand up, I don't stand with equal weight on both legs, I have a tendancy to choose a side and put most of my weight on one side, and switch to the other side when I get uncomfortable.
I like to stare at people when they are not looking and when they are about to look my way, I look somewhere else. I started as a child.
I crack wrist knuckles, ankles, sometimes elbows, and my left knee. My left knee feels some tension especially when I get outta bed, like it feels outta place, so I have to kick my leg out to crack it and the tension is gone. I notice I have to do that to my leg since I twisted my knee playing soccer at 15. I crack my neck also when I feel tension in it.
