I do not believe that face-coverings make the slightest bit of difference to the spread of Covid 19. But, I am legally obliged to wear something - anything - over my mouth and nose wherever the Scottish Government decides I should.
I've had a look at the coverage of last week's announcement that face-coverings are to stay for a while longer, but the only reason I could see being given was that it would be "prudent"!
Can anyone here point me to an evidential basis for the Scottish Government's decision?
Yesterday I had a lovely wander round Asda sans mask - exchanging conspiratorial glances with others who had the audacity to expose their face to the world.
