Think the comments re 'virtue signalling' are a bit unfair. Most people are following what they consider to be sensible guidance in the circumstances. I would have thought that the term equally applies to those who chose not to wear them given the current 'instructions'. I must admit that I find the mask an absolute pain, as I am sure all those who wear glasses do, and would rather not bother but having sad that I will follow what is expected as surely it can do no harm and may even do some good even if the statistics are a bit uncertain.
