If you're too lazy to Google it for yourself, here's a history of the Blue Zone research, how the original "researcher" is profiting off of it, and the careful work that has been done to debunk it: https://www.science.org/content/article/do-blue-zones-suppos...
But I am not seeing any evidence that the general public is aware of this. And thus we need more of the articles "asking" this question so that more people are aware of the issues on it.
FYI, the article you linked basically tells the same story as the topical article. Are you too lazy to read it before commenting?
B) Regardless of what story it tells, the article is an opinion piece by a journalist and a cardiologist, not authorities on the topic, and has a misleading title: that "answering [the] question [of whether Blue Zones are real]" is harder than ever. It's not.
Which is fine, although I personally wouldn't use "can't" to describe this stance. In any case, I think the discussion might be smoother if you were willing to review the article under discussion.
