What is the secret to living past 100? This question is increasingly attracting the attention of researchers, while a rare story from Brazil has begun to be analyzed by scientists. Three Brazilian sisters, with a combined age of 316 years, have become part of a scientific study, as they are considered among the longest-living sisters in the world.

They are Zulina de Deus Nunes, 103 years old, Zoraide de Deus Mota, 104 years old, and Levita de Deus Nunes, 109 years old. All three have lived different lives, but characterized by activity, dedication, and strong family ties.

Throughout their lives, they have worked, raised families, and faced various challenges, always standing by each other. According to researchers, their simple habits, physical activity, and family support may be some of the factors that have influenced their longevity.

The story of the three sisters is part of the DNA Longevo project, led by scientist Mayana Zatz from the University of São Paulo, which aims to discover the biological factors that influence healthy aging.

Researchers are comparing people who have reached very advanced ages with those suffering from age-related diseases, with the aim of identifying genes that may offer protection against aging.

The organization LongeviQuest helped verify the ages of three sisters, who live in Rio de Janeiro. According to experts, genetic inheritance can have a significant impact on maintaining health in old age, but lifestyle also remains a decisive factor.

The three sisters say they grew up with simple foods, a more natural lifestyle, and strong family relationships. For scientists, their story is further evidence that longevity is not related to a single factor, but to a combination of genetics, physical activity, nutrition, and emotional balance.
