You and me both. I have been up and down this country several times since the pandemic started, on airplanes, in restaurants, at outdoor concerts, in stores, everywhere. I do wear masks (as required) indoors, but never outside. And I have felt sick a few times in the past year. But every single time I check if I have an active Covid infection or antibodies...nothing. Frustrating, because I wish I found out that I already have natural antibodies.
I think it just depends on the individual biology. I just know that I’m very grateful - I’m aware of some people among my acquaintances who have had a bad time with it.
