While wearing a mask is never a bad idea, it is absolutely not necessary to not get sick. I am also immunocompromised and I have stopped wearing a mask. I wash my hands very often and never eat handheld food without washing first. Zero issues since getting covid back when I was wearing a mask religiously.
It’s just a class that is absolutely exploring people. You can’t become a billionaire without it. You can absolutely become an honest millionaire so it wouldn’t make sense to use that.
