I didn't literally mean that people don't ever make it to 100, just that it seems plausible that incorrect reports (fraud, error, etc.) are orders of magnitude

I didn't literally mean that people don't ever make it to 100, just that it seems plausible that incorrect reports (fraud, error, etc.) are orders of magnitude more common on a global level. Imagine trying to study longevity with data that has 4M or 40M erroneous centenarians and only 450k real ones. Some of these isolated 'blue zones' are cults/small communities that may also have a conflict of interest in convincing people that their way of life leads to longevity.
