Is fraud a factor in remarkable age records?

Supercentenarian and so-called "remarkable" age records show patterns indicative of clerical errors and pension fraud, Saul Justin Newman, PhD, a University of Oxford, UK, professor writes in a report that is published, but not yet peer-reviewed (preprint). He notes that the concentration of people colloquially known as super-agers within geographic regions or "blue zones" has stimulated many efforts to understand the factors driving survival in these populations. Researchers have analyzed lifestyle patterns, social connections, biomarkers, and genomic variants, he writes, "under the assumption that these are the potential drivers behind the attainment of remarkable age."
