I shiver occasionally, regardless of temperature or emotional state. I also have a couple weird muscle tics, like my right eye lid occasionally flutters and a really weird one where I jerk my right shoulder up and tilt my head to the right so the two almost touch. Again, that tic does not happen often but tends to happen more when agitated.
I'm also a huge perfectionist to the point I will correctly repeat phrases that I screw up when speaking as far back as around a minute, when I find a typo in a sentence I just typed I have to delete all the way back to the messed up word instead of clicking the typo with my cursor, I mentally rehearse conversations, and I sometimes whisper what I say immediately after I finish saying it. I believe that last one is called palilalia. I don't do it as often as I used to since I'm more aware of it, but it still happens now and then.
When talking on the phone I have to walk around. I also daydream a lot, which is occasionally a problem. Luckily it has not resulted in any accidents or injuries yet. I always wear at least two layers of clothing on my torso, usually a t-shirt and a button down shirt or a t-shirt and a hoodie.
