Exactly. I find it strange that someone who's immune system is compromised to the point where a 'common cold' can kill them has been just hanging out in public and it's only a problem now. Masks weren't invented in 2020. Op is likely farming Internet points.

I've had a compromised immune system before. Going out in public and trusting a mask to protect me would be like wearing safety goggles when you jump into a wood chipper.
