I have a tendency towards obsessive compulsive disorder (OCD).
One area this manifests itself is in my freezer.
I like frozen food. It keeps in nutrients and, as a single man cooking for one, is convenient and low in waste.
But my OCD kicks in and I end up buying way more food than I can possibly eat.
As a result, my freezer is so full that the door will not stay closed. I've had to install an elasticated cord just to keep the freezer door shut.
