I just watched that documentary the other night.
Very sad stories from the survivors. I particularly remember the older gentlemen who recalled losing almost all of his childhood friends during the second wave, which hit in October and caused daily deaths by the hundreds in major urban areas.
I also took note of the question, why does history tend to gloss over the pandemic, or even forget it? The answer, and the one that I subscribe to, is that the pandemic was so frightful and tragic that people wanted to forget about it and move on.
I believe it’s Human Nature to run from the evil when confronted with it. Look at the world post World War II. Going into Korea nobody wanted another War because it’s horrible. I think the pandemic and the actual results of World War 1 just made the world want to forget what just happened
