Here's why masks are useless: You are going to take your mask off with your dirty hands. You're going to wear your mask dutifully while outside, then you're going to walk inside your house and the first thing you will do is take your mask off - with your dirty hands.

There are so many gotchas with wearing masks that it's best to just leave them for the people who are closest to the crisis. They're the ones with the greatest need and they have the training to make them effective.

And besides... the coronavirus is not airborne, you need to be hit with a droplet from an infected person's cough or sneeze. There's such a small chance of that happening while you're out-and-about that it's not worth it to wear these things. The real solution is to wash your hands because that's the main vector of infection.
