In villages on the eastern coast of Sardinia, people live longer than anywhere else in the world. But how? Is it due to nutrients? Is it due to the good weather or genetics? Scientists around the world are trying to solve this mystery. 91-year-old Antonio leads a busy life. Every morning he milks his sheep and then makes cheese from it. Antonio says, "Work is my life. If I stop working, I'll die." Like many Sardinians living in the mountainous region, he and his wife eat almost exclusively local produce. Exercise and a healthy diet are their secrets to longevity. Giusepino is over 100 years old. He still walks most of the streets of his village, Villagrande. Is this unforgiving mountainous terrain the secret to his longevity? Giusepino's family takes care of him, but he still lives alone in his flat and is full of energy. According to her, a positive attitude and a sense of humor are the keys to her longevity. Despite extensive research, the secrets of the Blue Zones remain undeciphered. However, a study conducted in this region has concluded that genetics play a significant role in the first half of life. 91-year-old Carolina clearly believes that a full family is a prerequisite for a long life. She has no intention of moving to a nursing home. For her, the most important thing is for a mother to grow old with her children. Preparing traditional food remains one of her favorite pastimes. #dwdocumentaryhindi #dwdocs #dwhindi #bluezone #centenarians #sardinia --------------------------------------------------------------------------------------- If you liked the video and want to see more such interesting videos, don't forget to subscribe.
