Researchers studied Maria Branyas Morera, who died at 117, revealing biological factors that protected her from age-related illnesses. Despite showing signs of extreme old age, her exceptionally short telomeres may have prevented cancer, while gene variants protected her heart and brain. Low inflammation and a healthy gut microbiome also contributed. Lifestyle factors like diet and social life played a role. The findings could lead to treatments to promote healthy aging.
