Thank you for history. Masking now is very different from masking then and pneumonia is more treatable. But open doors and open windows are easier now. VD3 is available. Lets take the balanced position changing what we must and accepting the historical that still makes sense.
I think your post is called wisdom. The top virologist in the eu recommends 2000 to 5000 units d3 a day for the course of the pandemic and return to a normal life.
He calls the Covid response a scam.
I prefer my science comes from the best in the field, not politician’s playing doctor on tv.
