#COVID19 is a disease which is caused (in part) by contaminated, stale air that's been breathed in and out by several other people already. Gross.
Why do we live with stale air?
Because people penny-pinch on heating and ventilation.
Save energy. Close windows. Catch a disease. https://twitter.com/RokoMijicUK/status/1321758977584234497

We could make life a lot better by introducing regulation to ventilate spaces better and make it easier and cheaper to do so. Air-conditioning can include internal UV lamps to sterilize the air, and in winter you can use mechanical heat recovery systems
You can see things like #COVID19 as a type of #TechnicalDebt that civilization accumulates.
It's cheaper to not ventilate spaces, and it's mostly not a problem. But then if you combine unventilated spaces with global travel and a larger population, you get a global air-plague.

I went to the local library today.
They had gone to immense effort to create one-way flows of people in the (large) library, put arrows on the floor, barriers, etc.
But the space has extremely poor ventilation and the few windows that exist are closed.

Similar story in cafes and bars; lots of disruptive bullshit, but no airflow, closed windows/doors, no ventilation.
We STILL haven't really understood some very basic things.
