Three sisters in Brazil have each lived past the age of 100, and researchers now want to understand what keeps them going. The women, who live in the state of Minas Gerais, have drawn the attention of scientists studying longevity. Their combined age exceeds 300 years.
A family of centenarians in rural Brazil
The sisters were born in the early 20th century in a small farming community. They have spent most of their lives in the same region, living simply and staying close to one another. Local people know them well and regard their long lives as something remarkable. The sisters are not famous, but their survival has become a point of pride in the area.
What researchers are looking for
Scientists from a Brazilian university have begun collecting blood samples and health data from the sisters. They want to examine their genetics, diet, and daily habits. The goal is to find patterns that might explain why all three siblings have reached such an advanced age. The researchers are also interviewing the sisters about their routines and what they eat. Early observations suggest they have always eaten a traditional diet with little processed food.
The sisters have outlived most of their peers and even some of their own children. Their longevity is unusual even by global standards. In Brazil, the average life expectancy is around 76 years. To have three siblings all live past 100 is extremely rare.
Why this matters for the rest of us
The study of very old people can offer clues about how to slow the aging process. If scientists can identify the genetic or environmental factors that helped these sisters, they may one day apply that knowledge to help others live longer, healthier lives. For now, the sisters continue their quiet lives in Minas Gerais, and the research continues.
