I wash my hands too all the time before I study. I often spun my pen unintentionally and realise it when it falls to the ground. I crack my knuckles all the time. When I read aloud for my Economics and Ancient History notes, I start walking around my room and then my entire house. If I'm studying with friends then it just ends up as a massive 2hr convo unrelated to studying which is why I prefer studying alone than group study. I constantly have to get up all the time, and drink some water or eat gum. I listen to music when doing maths. Sometimes, I read on my bed curled up lol..
