>I literally possess binary memory when it comes to "what is clean" and "what isn't clean (touched the floor, public restroom, etc)" for most of my things.

after working in tissue culture where sterility matters (to put it lightly) i have developed a similar mentality. in the lab, it teaches you to be overly careful with things because a lot of the time you have to throw them out if they get dirty, and often the bar for "being dirty" can be as low as "was exposed to air while uncovered". it causes a lot of very wasteful carryovers into real life.
