Deep dives

Reevaluating Longevity Research

Recent investigations suggest that common beliefs surrounding longevity may be fundamentally flawed. Research by an interdisciplinary scholar reveals that significant portions of demographic data on extremely old individuals, particularly centenarians, are riddled with inaccuracies. This has led to the conclusion that many claims regarding factors contributing to a long life, such as the Mediterranean diet or social connections, may not withstand scrutiny. Notably, evidence points to a correlation between reaching extreme ages and places with poor record-keeping and high poverty rates, challenging long-held assumptions in the field.
