But they have huge open spaces with really high ceilings in many cases.. There's lots of air for it to dissipate in. And they're made to handle so many passengers, only a fraction of whom are there now. When I flew around in summer you could hear a pin drop :)

I feel a lot less safe from covid in the metro or bus here even though it's not as busy as it was before, than in an airport, plane or office. Even a taxi.

Still, I'm not going to live in one though :) My house is even better.
