Aiming for longevity

Genetics, lifestyle, and environmental factors contribute to reaching age 100. More than 100,000 people were 100 or older in 2019, triple the number in 1980. People reaching extreme old age tend to be nonsmokers, are not obese, and cope with stress effectively. Studies show that diets incorporating more fruits, vegetables, and whole grains may lower the odds of frailty and increase life span. Siblings and children of long-living people also are likelier to live longer than peers. Optimism is associated with higher odds of living beyond 90.
