Maria Branyas Morera, the world’s oldest woman, lived to 117 years and 168 days before passing away last year. Born in the U.S., she moved to Catalonia in 1915 and stayed there for the rest of her life. She witnessed two world wars, the terms of 21 U.S. presidents, and rapid advances that reshaped modern society.

Before her death, Maria wished her DNA be studied to help others live longer. Researchers from the University of Barcelona and the Josep Carreras Leukaemia Research Institute analyzed her genetics and cellular health. Dr. Manel Esteller explained, “For the first time, we’ve been able to separate being old from being sick.”

The study found her biological age at 117 was closer to 100–105. She had low levels of harmful cholesterol and triglycerides, while her “good” cholesterol was unusually high.

Her healthy habits also contributed. Maria exercised, avoided alcohol and smoking, and enjoyed a rich social life. Her daily routine included a smoothie with eight grains and La Fageda yogurt, which she credited with supporting her health.

Surprisingly, her very short telomeres, normally a sign of aging, may have protected her by limiting cancer cell growth.
