The main reason you should wear a mask is to protect others. It is so-so at keeping the virus out, but it is very good at keeping the virus from being expelled into the air. Since a large number of people who get it never show symptoms, or it takes 2-5 days or so for symptoms to show, it is important for everyone to wear a mask. Some say it is their right not to, but that’s not true. You do NOT have a right to put others at risk. You have a right to own a gun, but you do NOT have a right to shoot it indiscriminately in public. It’s too bad our leaders do not have the foresight to require them, and enforce it, across the board. If you are not wearing a mask, then don’t complain about the backtracking on opening up and getting back to normal, because it’s mostly your fault!
