Ever run to catch a train? Ever have to run from a train on platform 8, go down the stairs, sprint 50 yards, then climb the stairs to platform 2, then march eight pullman cars back to the one with your reserved seat - all while lugging a 50-lb suitcase and a 2-y-o child?
Regards,
Nope, but if I did, the cheesecloth mask wouldn’t be a problem. I can generally plan things to avoid having to run a lot.
