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.
