Treat Every Bathroom As If It Were Your Own
Not sure what it is about airport and stadium restrooms that drags us back to our primitive roots, but these places are vile. If you need a reminder for just how little progress mankind has made since Ardipithecus ramidus, visit the toughs at Wrigley Field, or hit the head at the Port Authority. Revolting restrooms are something we all needlessly deal with, but would be easily improved by, you know, not pissing all over the floor. And flushing.
