On local Australian TV news a day or two ago, I saw a passing shot of a nurse wearing her face mask differently from everybody else that I've seen so far in all the news reports from around the world about this COVID-19 pandemic.
See the image below, where the blue lines indicate how the loop is twisted (compared with the usual untwisted method in white).
I tried it out "the twist" today, and it seems less likely for the mask to come loose, and it seems to reduce the problem of the ear loops getting tangled up with the arms of your spectacles.
Try it out yourself. What do you think?
