Oh, I don't. I had the Rona. Equivalent to a cold for me. I have the antibodies, and I have been around a lot of people with it over the last year. No symptomatic reinfection. I don't work around many people, so the 3 of us have small bubbles. We're all good and have all been good since March of 20. But I know a lot of people that have the same mask on all day, they wear the same cloth mask day after day and just wash it on the weekends, maybe. I know one guy that just let's his dry out on the mirror in his car in the sunlight too. Most of them have all been pretty sick over the last year and a half, at least twice, but none of them since about may.
