Brazilian Sisters Aged 103, 104, and 109 Aid Genetic Longevity Research
Three Brazilian sisters aged 103, 104, and 109, recognized by Guinness World Records as the oldest living sibling trio, are aiding scientists studying longevity. Led by Mayana Zatz at the University of Sao Paulo, the DNA Longevo Project investigates genetic factors that may protect against ageing effects. Researchers compare healthy centenarians with those experiencing age-related decline to identify protective genes. The sisters attribute their long lives to genetics, a healthy diet, and active lifestyles, residing in Rio de Janeiro.
