I got up early today, because I was giving a new lecture today, and while I got most of it done last night, I was plumb wore out then and told myself I’d finish it in the morning…which I did. Then I had to give the lecture, and immediately afterwards run over to the hospital for an echocardiogram.
This was routine, my doctor just wanted to check that I have a heart, or that it kinda sorta works. I do, and it does, but there was a little accident. They put in an intravenous line so they could inject me with some kind of contrast agent, and when they punched in, it sprayed out — a little jet of blood splattering me, the bed, and the doctor (sorry, doc). It was much messier than it needed to be, and made everything a bit splatterific. I didn’t mind, but it was just that kind of day.
Then I had to teach a lab for a few hours: this lab was all math, basic unit conversions, volume calculations, etc. Most of our bio students aren’t comfortable with calculations and managed to twist their brains around multiple times, so I had to explain why yeast cells probably don’t have a volume measured in liters and how a lake a kilometer across probably has more than 100 microorganisms floating in it.
Now I’m all wrung out, and am counting the minutes to bedtime.
