Making progress?

I spent very little of the day out of bed. When you can't sleep for coughing, and you can't concentrate enough to read, and you haven't the strength to do any of the growing list of chores, what do you do?

I finally managed enough energy to finish watching a youtube series I've been watching(*): unfortunately he's only about 3/5 done with it.

I think it was Erma Bombeck who wrote that being pregnant was like taking a cruise in at least one respect: you might just be sitting in a chair watching the ocean, but you're making progress.

As long as I sleep a little longer, and cough a little less, I suppose I am.

UPDATE: My teaching daughter said 2/3 of 3'rd grade was out sick yesterday.

(*) Including "the square root of a vector". The series is much more accessible than the titles suggest, though you do need to have a little matrix theory under your belt. He repeats everything, and uses simple examples. It's nice to see an explanation of Clifford algebras, and how spinors can be represented in them, but it isn't transparent what gain we then have in comprehensiveness, new physics, or simplicity.
