Fell into a rabbit hole about “blue zones” the other day and I wanted to map out counties with the highest percentage of people over 100 to see if there was anything resembling a blue zone in the US. Can’t tell if the Great Plains is a blue zone or whether a lot of old people just happen to live in these counties and so of course there’s more likely to be centenarians lol.
