So I live in a part of the US where I haven’t seen more than 2 or 3 people wear a mask (outside of a protest I went to) in the past two years. Its genuinely just not done here. I will wear a mask if I feel a under the weather or my allergies are acting up but typically don’t wear one. Should I? Would it help? Do y’all wear one everytime you go out?

As I understand it masks don’t prevent you from getting sick as much as they prevent you from getting others sick. Is this correct?
