So who is to be trusted to make the right call on timing? Or isn't there a right call? If we knew that the thing would go away completely, I'd be with you. But the likelihood is that it'll be here forever. So what measure are we going to use? I've seen footage of those countries in Eastern Asia where people routinely walk around with masks on. Well I don't want this country to be like that. I don't think it's a virtuous mindset. I think it's a neurotic mindset. It exudes mistrust of other people. There has to come a point at which we decide that it's up to you. It's already up to you whether you sanitise your trolley handle. It's up to you whether you wash your hands after visiting the khazi, as with after blowing your nose (many healthy people's noses always harbour pathogenic bacteria - look it up). It's up to you whether you sneeze into a tissue or just let rip with glorious freedom. It's up to you if you want to go out and about, mixing with others or going to work, with a cold or flu. And so on. Things we definitely know can be harmful to others. Yet we don't legislate for those things at all. Instead, we legislate for a measure about which there's uncertainty as to its efficacy. We're a bit mad, aren't we?
