Maria Branyas lived to 117, and scientists just found out why—her DNA was basically stuck in youth mode! She had rare genetic variants linked to a healthy heart, brain, and immune system, plus super low inflammation and cholesterol. Even her gut microbiome looked young. While her Mediterranean diet helped, her genes were the real MVP. Researchers say her case could help unlock secrets to living longer, healthier lives. Imagine having cells that act decades younger than you are! #Science #Longevity #Genetics
