So basically, I sat unmoving at my computer for 7 straight hours, forgoing lunch, working on wikipedia, until my bladder finally forced me to get up. When I got up and went down to make dinner I started shivering (it's warmer upstairs than downstairs) and only then realized I'd gotten chilled.
God help me, I need to find someone who will hire me to do this kind of work. If it can make me forget all bodily needs for 7 hours straight, obviously it's what I ought to be doing.
