maedaliyah> That either we never wear masks or we always do?
I agree. I would start with – whenever governor of your state mandates it, and when other people expect you to do it, such as in the stores, offices. It is also not an only choice. “wearing mask” became a short-hand for this madness. There are lots of other decisions you can make. for example, not too fly for a vacation on Spirit this year, limit other optional things and find appropriate, or even better, substitutes, such as learning Torah, gaining a profession, spending more time with yor spouse and kids. I would presume that, for example, Vilna Gaon, would not need to wear mask much, as he rarely ventured out of his house.
