Off the top of my head, of the things mentioned I only do the battery one (where the batteries must face outwards), and the fresh-water-in-kettle thing. On a web page with lots and lots of text, I highlight the bits that I'm reading read with the mouse. Makes it easier to read somehow....RTT laughs at me for this When puttings CDs back in their cases, they must go the right way up where possible (so the text saying what the CD is level and centred). When listening to music, I have to tap along to the beat...to do otherwise feels weird. When locking my car or front door, I always yank the handle and push the door to see if it really is locked.
