Words: 500 (in the form of 15 minutes). I have a massive headache, so I took the chance to do just a small amount of work that didn’t require too much thinking. My Skype revision group is planning to go back soon to work on some exposition parts we’d skipped before. I had some updated notes on those sections that needed putting into our shared file, so I did that. Now I have to go lay down and keep my brain from oozing out of my skull.
