Maria Branyas, the oldest person in the world, is participating in a scientific study to find out what lies behind her longevity. Researchers point to privileged genetics and positive habits. 

When asked about her secret to long life, 117–year–old Maria Branyas from San Francisco, regarded as the world’s oldest person, modestly responds, «I’ve done nothing to live this long. I have no merit.» Branyas, who resides in a senior home in Olot, Girona, recently celebrated another birthday with a simple party, carefully organized into small groups to not overwhelm her. Branyas, although experiencing a decline in health, remains aware of her surroundings. Her life changed dramatically in 2023, when she became the oldest living woman on Earth following the death of 118–year–old Lucile Randon from France. Branyas‘ life has been a subject of interest for many, including cancer expert Manel Esteller who wished to study the cells of someone of her unusual age. Despite her age, Branyas looks forward to death and continues to live each day as serenely and joyfully as possible. Her cells, according to preliminary findings by Esteller, appear to be about 10 years younger than her chronological age. Branyas‘ longevity, her daughter suggests, could be attributed to a stress–free life and a healthy Mediterranean diet.
