Scientists are studying the longevity phenomenon of three Brazilian sisters who are already over 100 years old

In Brazil, scientists are studying the phenomenon of three long-lived sisters, each of whom is more than 100 years old. Researchers hope their unique genetics and lifestyle will help them better understand the mechanisms of healthy aging.

In Brazil, scientists are studying the phenomenon of three long-lived sisters, who are already more than 100 years old, writes xrust. Reuters reports this. Researchers hope that the unique combination of genetics, lifestyle and social factors will help better understand the mechanisms of healthy aging and provide new guidelines for medicine.

The sisters live in the state of Parana, in southern Brazil. The eldest is 107 years old, the other two are 104 and 100. Despite their age, they retain clarity of mind, the ability to move independently and actively participate in family life. For scientists, this is a rare case when several relatives overcome the century mark at once, which makes it possible to study longevity not at the level of individuals, but at the level of family lines.

The study is conducted by a team of gerontologists and geneticists who collect data on the health of the sisters, their habits, medical history and lifestyle. Particular attention is paid to genetic markers that may be associated with delayed cell aging, resistance to chronic diseases and preservation of cognitive function. These familial cases provide an opportunity to identify rare genetic variants that are difficult to detect in routine population studies, the scientists say.

However, researchers emphasize that it's not just about genes. The lifestyle that the sisters led for decades plays an important role. They grew up in rural areas, worked hard physically, ate simple home-cooked food, and spent most of their lives actively moving. Their diet was dominated by vegetables, legumes, corn, seasonal fruits and a minimal amount of industrially processed foods.

For the Russian reader, it is important to note that such factors — moderate physical activity, natural food, low stress levels — often appear in studies on longevity. But in the case of the Brazilian sisters, these elements are combined with genetic characteristics, making their story especially valuable to science.

Scientists are also studying the social aspects of the sisters’ lives. They lived all their lives in a large family, surrounded by relatives and friends. Support from loved ones, regular communication and a lack of social isolation are factors that current research has linked to a lower risk of cognitive impairment and depression in old age.

According to researchers, psychological resilience and a positive attitude may play as much a role as biology. The sisters say that they always tried to remain calm, avoid conflicts and support each other. Scientists note that emotional stability is one of the underestimated factors of longevity.

The study includes blood tests, genetic tests, assessment of the state of the cardiovascular system and cognitive functions. Scientists hope to identify biomarkers that will help predict the risk of age-related diseases and develop new approaches to prevention.

In recent years, interest in the study of centenarians has been growing throughout the world. Scientists are trying to understand why some people live to be 100 years or older in good health, while others face severe chronic diseases as early as 60–70 years of age. Research shows that longevity is the result of a complex interaction of genetics, lifestyle, environment and social factors.

Brazilian sisters became part of an international project that combines data on centenarians from different countries. The goal is to create a global knowledge base that will help develop healthy aging programs and improve the quality of life of older people.

Scientists emphasize that the results of the study will be useful not only for medicine, but also for social policy. Understanding the factors behind longevity can help governments design programs to support older people, develop infrastructure for active aging, and reduce the burden on health care systems.

Despite their age, the sisters continue to lead an active life: they communicate with relatives, do household chores and remain interested in what is happening around them. Their story is inspiring and shows that longevity is not only biology, but also lifestyle, environment and attitude to the world.
