My wife and I are coming out of a little over a week of extreme fatigue and brain fog. We get out very little, have had zero visitors for 2 weeks, so we were left wondering about the source and vector of our illness. As we compared our activities prior to getting ill, the body of evidence began to build. For a solid week prior we had used the exercise bicycle I had dragged up from the basement.
It seems to be pretty conclusive, once I got sick, I stopped exercising, and now I am feeling much better. It seems as if I had banished the Machine of Death to the basement for a reason.
