I’m very confident I’ve been exposed to covid, yet never had any test or conclusive symptoms.

I’m also confident that people like me do not experience problems from covid. At least not any more problems than a flu. A 1/3000 risk of myocarditis is not something I will risk. That’s a long term scarring of heart tissue, similar to how my father died in his 30s from teenage medical treatment.

The difference in your statement is that covid is an acute condition rather than a chronic slow growing tumor. If covid took years to show symptoms it’d be a reasonable comparison, but it’s very silly to make otherwise.
