Three Brazilian sisters,now recognized by Guinness World Records as oldest living trio of siblings,might unlock secrets of longevity . At combined age of 316 years,their case draws researchers eager to probe aging's biological roots .
The DNA Longevo Project,led by scientist Mayana Zatz from University of São Paulo,seeks to uncover factors behind long life. Zatz,heading the university's Human Genome Research Centre,stressed importance of studying such individuals to find genetic traits linked to longevity. “Through DNA testing,we look for protective genes,and we know there are several of them,” she said.
Researchers compare centenarians and nonagenarians with those facing frailty or cognitive decline. Aim to spot traits tied to long,healthy life. The sisters’ longevity might shed light on why some keep physical,cognitive strength into old age .
Zatz said more families with multiple centenarians involved mean more accurate findings. Study continues to explore genetic,lifestyle mix leading to longer,healthier life. But can science truly decode the mystery…?
