I used to have something I believe to be a mild form of OCD, if my hand touched, say a wall as i walked past, I'd have to touch it again, then i'd touch it again to make it up to 8 times, then another 8. It was very annoying, but I don't know what happened to that, I just kind of forgot to do it, and never do anymore. lol maybe weed helped it, I don't know
