Or those of us that have to for work
Sorry, yes, there is a group here of those, however they also fall in the "so regularly exposed there's little chance they haven't had it in the last 3 months of few restrictions", when talking about why gross statistics about whole populations you have to generalise across the population - that's what the statistics are doing.
And I apologise for characterising "nervous" as such a negative, I don't thin it is - I didn't know how to say "people who are more concerned about covid will test on fewer or lighter symptoms" that sounds just like nervous to me.
