You’re more than welcome. I started looking heavily into flu pandemic stuff in 2006 when H5N1 bird flu was infecting people in INdonesia, IIRC. I stuck with studying stuff for several years, and learned a lot more than I ever though I could. Some remains in memory, someplace... Flu (and other) pandemics are no joke, and have caused massive deaths in the past and modern medicien is not necessarily a match for all of them. It’s not like “Oh, that can’t happen any more”. Nope. Mother Nature rules.
The thing that worries me is that the Chinese have never been loath to admit that they would like to reduce their numbers.
