And nothing else matters. I had Fauci's Flu in Dec 2020. I haven't even had a cold since then and I am usually good for at least 2/year. You can attribute it to masks. I will attribute it to people washing their hands.... more to the point... that I am washing my hands more.
Anecdotal but I’ve had the same experience. Knock on wood but I have as long of a run as I can remember without a real cold, over the last 2 years. I did have Covid, once for sure, quite likely twice. No symptoms either time.
