Depending on where you live, you might be seeing masked joggers and cyclists on the streets of your neighborhood. Or you might have gone for a run yourself, mask-free, and been heckled to mask up.

Presidential candidate Joe Biden added to the confusion when he called for a national mask mandate last week. In no uncertain terms, he said it could save 40,000 lives over the next three months if everyone wore a mask “outside.”
