That could be me, but I'm not about to test that

But hey, it says "fun fact" on it and it's on the internet, so it must be true

Okay, so it's not entirely proven that surviving the plague was the cause, and in most cases jt brings increased resistance, not total immunity. Still hecka cool though.

There was, it just wasn't nearly on the same level as the outbreak in Europe

Most of the deaths in Europe where also concentrated in large densely populated cities. More people in europe lives in cities than people in Asia thus more deaths. That plus European vs Asia cultural habits regarding cleanliness (i.e. hand washing, not wearing shoes indoors, not letting animals in your house, don’t shit in the water your drink) meant Asian communities were a lot cleaner than European ones. Dirty living + close living quarters = tons of death in Europe
