I tried to find the post on FB but it seems vanished. No FB revelation what this was about - or not about.[/quote]
Thanks for the update.
I pasted some of your quote in Google, and the Facebook post(s) didn’t show up, but at the time, I figured that was because Google hadn’t crawled (or Google-danced, or whatever that voodoo is that they do so well) the latest posts on Facebook yet, or hadn’t finished crawling them.
So this goes under “unsolved mysteries.” Still, it was interesting, and I learned something about heavy-metal pollution in the Taichung area.
