I work at a public office, see hundred of people daily, touch all they are touching and giving me, and I don't think I ever got it.
If I did, I was asymptomatic. I've never been contact case, and never have been tested either.
So far, I also didn't get any other illness, no flu, no cold, nothing for years. Maybe being careful and applying barrier gesture is enough for me. (mask, washing hands, distance, not doing stupid things like licking my hands or touching my nose with unwashed hands...)
Or maybe my immune system is very much boosted due to being in contact with a lot of people every day. seems T-lymphocytes are acting against Covid too, which I might have in excess being exposed to so much potentially ill people every day.
that's just hypothetical, I never did any blood test either.
Or maybe I'm immune to covid, and government will try to catch me and open my brain to make a vaccine.... wait, I've played too much zombie games and seen too much scifi movies
Other than my work, I only go out for shopping. I don't go to crowded places, or restaurant, events, etc. just common senses.
