Jarring that after years of lurking HN I come across a reference to someone I know personally. While I can’t speak to the legitimacy of the original cancer diagnosis, I can say that family oral history from long before the Blue Zone popularization is filled with this kind of story. Immigrants (usually first or second generation) returning to the island to get well. Anecdotal to be sure, and there are stories in the same vein about many old country birthplaces, but the supposed healthful qualities of the island have a long history, stretching back into antiquity.

Still anecdotal but more personal: the original immigrant generation that I descend from all died nonagenarians or over 100. There seems to be diminishing returns on that sadly, as each successive generation’s life expectancy seems to be more “normal.”
