> According to the Blue Zone researchers, some of the Blue Zones are disappearing because the generations that came after the oldest live differently and much shorter.

Of course they would say that. But if these zones are simultaneously recording births better and reducing welfare fraud, and if 80%+ of the centenarians either had no birth certificate or were actually dead, I'm going to need more than "but they're also changing lifestyles" as an explanation.

We're talking here about unusually long life, not just "he's still going strong at 85" long. No one here is arguing that people who are active and eat right don't have a longer healthspan, but that's a concept that's provable without the so-called Blue Zones.
