It's not that I think face masks are totally ineffective in preventing the spread of Covid-19. But probably they are more of a statement of conformity and a reminder for others to "keep their distance" than having any real benefit. It's pretty clear that they do not stop all emanation of droplets from the wearer's nose or mouth but arguably they might direct airflow to the sides and thus away from... well that depends on where the objects of contamination are standing...
And then there is the argument that a mask will harbour nasties and thus exacerbate the problem. I've spoken to a qualified nurse involved on the front line and she pointed out that medics should replace their mask every 2 hours to mitigate this effect, thus clearly admitting this problem. Meanwhile the rest of us indefinitely re-use our single-use masks.
There is a considerable degree of absurdity about the whole issue of face masks. There is also a deal of misunderstanding like a neighbour I noticed mowing her rear lawn whilst wearing a face mask. Or a cyclist passing me wearing a face mask. Presumably they mistakenly think it will protect them? But I reckon the following examples take the absurdity ticket.
I happened upon a Youtube video of Gustavo Dudamel conducting Mahler's Adagietto from Symphony No. 5. to an empty outside auditorium. All the musicians were not only socially distanced but also wearing face masks! In that video there were only strings and a harp but take a look at these pictures below that I grabbed from the internet. An apt comment on one web site was: How useless , ridiculous and humiliating for the poor musicians who are ready to accept these inhuman conditions in order to keep their job and continue their passion.
