I had a cousin's know it all husband throw this in my face when I explained why I still masked at work.

I responded that the Nordic country that implemented no measures and simply let covid rip through them (maybe it was Sweden??) has simply seen more deaths than its European neighbours who did mask and quarantined and such. So the idea of immunity debt by failing to catch a disease isn't really panning out in reality.

Of course now we see people regularly catching covid like 2 or 3 times a year, and every study just keeps getting bleaker about what that's doing to a body with each infection.

I'll take my mask off when I'm dead.
