I’ve been yelling expletives across the street at people who cough or sneeze sans coverage for my whole adult life. Needless to say, that practice has only grown more prevalent during the pandemic. It drives me crazy. And speaking of crazy driving, this morning, in a parking lot, I powered-rolled up my window and literally swerved my car to avoid an open-air hack-cough and the germ cloud it blustered in my direction. Obsessive? Perhaps. Correct? Most definitely. As long as we’re intermingling with others who insist on huffing and puffing, we need better ventilation and more effective ways to keep their germs from our lungs. It’s good for preventing Covid. It’s good for avoiding a lot of other respiratory illnesses as well. It’s also probably good for my driving. Sarah Zhang in The Atlantic: The Plan to Stop Every Respiratory Virus at Once. “To understand why pathogens can spread through the air, it helps to understand just how much of it we breathe. ‘About eight to 10 liters a minute,’ says Catherine Noakes, who studies indoor air quality at the University of Leeds, in England. Think four or five big soda bottles per minute, multiply that by the number of people in a room, and you can see how we are constantly breathing in one another’s lung secretions.”
