//If scientific advice is to do it then whats your issue.//
My issue is well known. The science is by no means unanimous and it changed for what I believe was a purely political reason. The WHO's advice was initially that they were of no use in commonplace settings and it changed to what is, at best, ambivalence once politicians realised that the social media hot lines were accusing non wearers of murdering their grannies.
BTW, I don't know everything, bob. I don't even believe that I do. I simply don't believe everything I'm told unconditionally, especially by politicians.
