I wonder if this article has some sort of selection bias. After all, communities that have the lowest and highest rates of cancer in the US are small towns of <100 people.
It's easy to find several small towns in the US where people have unusually high longevity. After all, you have many to choose from.
What's more curious is to make a hypothesis around diet and exercise, and then show causality across all similar islands in Greece.
There's also crazily high variation in rare events, like living past 100 or surviving "incurable" cancer. But those are the things which people are interested in.
