Doctors have been studying the DNA of Maria Branyas Morera, a Spanish-American woman who lived to the remarkable age of 117, in hopes of uncovering the secrets behind extreme longevity. Born in San Francisco on March 4, 1907, she witnessed more than a century of global change, from world wars to modern technological revolutions. After moving to Catalonia in 1915 with her family, she spent the rest of her long life in Spain, eventually becoming the world’s oldest verified living person before passing away in 2024.

Before her death, Maria made a unique request for scientists to study her genetics, believing her extraordinary lifespan could help others live healthier and longer lives. Researchers from the University of Barcelona and the Josep Carreras Leukaemia Research Institute analyzed her DNA, cells, and biological markers. Lead scientist Dr. Manel Esteller explained that Maria appeared biologically far younger than her actual age and represented a rare case where aging did not necessarily equal illness.

The findings revealed unusually healthy cholesterol levels, strong metabolic markers, and protective genetic traits that may have slowed age-related decline. Scientists also studied her lifestyle, noting her consistent physical activity, avoidance of smoking and alcohol, and strong social connections. One surprising detail was her daily consumption of probiotic yogurt, which researchers believe may have supported gut health and reduced inflammation over time.

Experts concluded that her longevity likely came from a combination of genetics and lifestyle choices, including balanced habits, emotional stability, and a positive outlook on life. Maria herself often emphasized simplicity, family bonds, and avoiding stress as key parts of her routine. Her story continues to inspire researchers, suggesting that while we cannot choose our genes, everyday habits may play a powerful role in how long—and how well—we live.
