Found out I was a close contact this afternoon and had to get a Covid test this evening. Decided to do my own little test when I got home by throwing on Revolver and seeing if my Cardiovascular system could keep up. Passed with flying colors. Pretty sure the Covid test is gonna come back negative.
When I had to travel through 2 airports on my way home in March, there was no Covid testing available and we had to self-isolate for 14 days. I used my daily indoor cycling routine to reassure myself that I was not sick.
Of course, this does not guarantee you not asymptomatic.
