I know that many of you back in my home country of Australia are suffering under the yoke of a Covid mask, but it can get worse, trust me. You see, the authorities in Philadelphia, and I found this out when visiting on business last week, think that wearing two masks is a great idea. No science backs this up, because if the first mask is inadequate, and viruses pass through, unless you have on so many masks that you stop breathing, it is not going to stop Covid-19. But, this is the politics of fear and social control, not reasoned public policy debate.
