Well, after keeping a relatively tight lid for nearly a year, I contracted Covid.
This is not a call for pity, just want to share how I got it and what it feels like.
I was driving a person for several hours and I requested that a molecular Covid test (not the rapid test) is taken prior to trip. I saw negative test results with my own eyes. Turned out to be a false negative. That solved the mystery of how I got it.

What it feels like.
Three main symptoms that I expierence are body temperature fluctuations, muscle aches and dizziness. But the one I did not expect is chills... regardless of thermometer readings. I just feel cold most of the time.
I have placed a space heater by the bed, that helps. Hopefully it does not worsen and I can sit it out. Not taking any crazy pharma, just your average C-D-E & zinc some advil to take the edge out of muscle aches and to reduce fever and lots of liquids.

The moral of the story, don't rely on test results too much.

Hopefully this thing passes like a bad dream and I would be able to attend to my music and other hobbies.

stay safe.
Misha.
