UPDATE - I'm still sick in bed and feeling like someone dropped a ping-pong table on my head, and I've decided I'm skipping this week's blog. (Don't worry, I tested for Covid, negative.) I'm going through Kleenex like multiball and coughing up stuff every few minutes. I don't think I've had a cold or flu like this in several years. I think I caught whatever I have last Wednesday, when I spent the day in DC touring Ford's Theater, and then a tour of all the major monuments - Washington (took the elevator to the top), Lincoln, Jefferson, MLK, FDR, WW1, WW2, Korean, Vietnam, and even the Einstein Memorial a few blocks away from the National Mall. I also walked around the White House and visited Lafayette Square, and then visited Spin DC Table Tennis, which was also just a few blocks away. So I was around crowds all day, and also on the jammed subway back and forth. I was supposed to spend Fri & Sat as a panelist at the Baltimore Science Fiction Convention, but had to drop out. I was feeling better Saturday night, and so coached two group sessions on Sunday - but near the end of the first one, I got weak and dizzy and had to stop about 15 minutes before the end of the session. (But I still came back for the second one.) Afterwards, whatever I have got worse. But I think it's just a bad cold, though I have some suspicions I might have had mild flu at the same time - had some stomach problems.
