If you haven’t, for example, persevered to write the Great American Novel through your brain fog, forgive yourself. (“great” and “american” aren’t the aspirations they used to be anyway.)
If you haven’t been to a cafe or pub in years, those places are gross and shouldn’t be given business until they improve their air quality anyway.
If the best you can do is hang out to see if science can rustle up some effective treatments, that’s a valid way to be.
