Futurology

Not sure if this is offtopic but...

My parents grew up in China but still emotionally abusive af, did China also have leaded gasoline, or did the wind just blew all the toxicity of lead from the US all the way across the world? (None of us even stepped foot in the US until like around 2010s, I think leaded gas was already banned by then...) 🤔

Or maybe my parents are just naturally born toxic... 😓
