As Glenn says, we’re going to see more people living to be this old. And as a commenter notes, there aren’t very many people left who were born in the nineteenth century. My maternal grandmother would have been two years older, had she lived, but she died at the ripe young age of ninety eight, fourteen years ago (whereupon I became a full orphan, and next in line, having no longer any living ancestors).
Of course, I take these folks’ recommendations for a long life with a healthy bag of salt. Particularly when they recommend a life of celibacy. I think that it’s good genes, and good luck, more than anything else.
