Strange then that i.e.: the Okinawa Blue Zone seems to have been dissolved in modern (record keeping) times.

In modern times it dissolved due to diet changes. Looking at the blue zone in California is one of the most enlightening because they can control for so many factors, the records are excellent, and the people seem to be generally open to being studied. There they have found how diet and lifestyle plays a huge role in longevity

In modern (record keeping) times it - might - dissolved due to diet changes.

Nobody disputed that a healthy diet is healthy. And a healthy lifestyle is healthy. Whereby lifestyle is such a broad word that its in fact meaningless.

Maybe the record keeping in Okinawa was correct.

If you look for outliers, you will find outliers.

If you look for correlation, you will find correlation.

Does not mean they are the causation for all the outliers.

So maybe Okinawa just had a lucky streak, which is now over.

The fact that these outliers share similar habits should put your concerns over "extraordinary" factors at bay.

but how many communities exist with the same behaviour/setting/factors configuration but are not an centaurian-outlier.

basic science, do not look for verification, but falsification

Well, record keeping and also an American occupation. From your link: "We believe that current loss of longevity advantage in Okinawa is a result of diet westernization"
