Your comments aren't the responses to my comments. Let's take an example, my comment is neither proposing a model for T2D nor saying CGM is part of any model.
You said Okinawa people eat a ton of pork, please compare with something.
You said they don't have birth record accuracy which is not totally true. In many asian culture, they use Zodiac and similar methods to keep track of age, the exact date may be off, but the year cannot be off because if it's off, that's 12 year difference. I cannot be a dragon and claim myself to be 84 when I am only 72 because all of my friends around know how old I am around.
When 1 or 2 persons say it, it may be mythical. But when most of population say it, there must be some truth. And it's also up to you how you believe it.
