I'm still getting occasional whiffs of it, of course. There are three reasons for that. First off, the carpet downstairs absorbed the stink; second, the odor molecules that are generated by rotting meat are sticky--once they get into your nose, they hang around and let you keep smelling the stench. Third, the stench molecules make a huge impression on your subconscious, so you keep remembering the smell. That's a survival trait, to make damned sure that you get the point not to eat rotten food.
I'm going to take a shower and put on clean clothes.
