1) I can't leave home without having checked that I have my keys, wallet, antihistamines, cell phone, epipen and that my oven is properly off (even if I haven't actually used it that day). Even if it's to go to the corner store to pick up a loaf of bread. I can check this multiple times before actually leaving the house. I think I have mild OCD but can't really be bothered to do anything about it. My friends call this my macarena dance.
2) Even though I can remember trivial facts from years ago, I have crap short-term memory and am therefore always writing things down on bits of paper. Every few weeks, I go through all my pockets and wallet to purge all a not insignificant biomass.
3) When I'm busy doing something, the world can crumble around me and I won't really notice it.
4) When I'm concentrating on something, I tend to tuck my chin in my shirt up to my nose. I can't really tell you why.
5) I'm addicted to my email and can check it, without exageration, about 150 times a day.
#2 could be written by me!
