No Secret to 100: Centenarian Research Reveals Many Tiny Advantages

A review of 124 studies on centenarians spanning 55 years finds no single secret to living to 100; longevity emerges from a mix of genetics, DNA repair, metabolism, lifestyle, social ties, and luck, with centenarians often showing more efficient cellular aging and healthier mitochondria. However, studying only those who reach 100 makes it hard to prove causation, and researchers classify centenarians as escapers, delayers, or survivors. Practical takeaway remains: stay active, eat largely plant-based, avoid smoking, and nurture social connections.
