You would think humanity would have learned.

When I was a little boy, I talked to people who lived through the great flu epidemic 1918. When I got older, I read more about it and thought, "Those silly historical people, how could they be so stupid?"

And we went right back and did it again, just as badly. Stupid, stupid humans.

Thanks for an absorbing article! I knew the one-line description, but you really put it together for me.
