>So were you going through life wearing a mask to mitigate the risk of a deadly flu in 2018 and before? I think probably not, but if your priority is risk mitigation, shouldn't you have been? During flu season? Of course. As well as soon any cold symptoms were felt. My institution would also issue stay-at-home recommendations during flu outbreaks.
You might have worn a mask during previous flu seasons, but it'd be helpful to acknowledge that almost nobody else did. Prior to COVID, masks were a curiosity, not a norm.
Only because we live in a “me” society and not a “we” society. If we were sensible, masking up would be normal when one has a cold/there’s a local flu outbreak. So much illness and lost productivity would be easily avoided with a minor change in expectations and behaviour.
