And is that the complete story wrt mask efficacy (against Covid transmission)? No it is clearly not, so banging on about it repetitively is a backwards argument and an irrelevant point.
And I do not need to be told I have to take a mask off to eat... and drink, nobody on this whole forum does so another moronic point!
Nor does anyone believe face masks are 100% effective at preventing Covid transmission so another foolish point from you! Perhaps like bullet proof vests, but I likely would still consider one in some situations.
Make relevant points and I may waste more of my time, but it would be wasted .... I have made similar points a multitude of times and am sure you will, for the umpteenth time, tell us again the Covid virus is smaller than 'pores' in face masks! Yeh.....
