My 84-year-old mother has horrible COPD. She tested positive and never had any symptom beyond a mild headache.
The difference? Very aggressive therapy treatment, including:
1) Having test kits ready at home (no 2-day appointments)
2) Getting antibody treatments within hours (in FL it was available 7 days a week until Biden turned off the spigot).
3) Having a drawer full of "horse dewormer" on hand.
4) Taking suppliments (esp. D3 + Zinc w/Quercetin) daily
This is all about to become ancient history, but at least we should know better how to deal with future viruses (including the good ol' flu).
We did the zinc/quercetin/NAC/d3/c for two years and a month. We flew 9 times and went out all of the time. Not vaccinated. Every happy hour we could hit, we did. Our eldest caught Covid and tested positive the day after we shared chicken wings off the same plate. We were exposed for a week. Nothing. My wife and I did the regiment but our son did not, he got MAT and was back to work in a week. We tested once a week after in case we wanted to get MAT but never had symptoms or a positive antigen test. We believe between God and therapeutics we were protected.
