Ethel Caterham, a British woman, celebrated her 116th birthday, making her the world's oldest living person. She quietly marked the occasion with her family. Caterham, born in 1909, outlived two daughters and her husband. She attributes her longevity to avoiding arguments and a positive outlook. While she received a letter from King Charles last year, it's uncertain if he'll contact her this year. Her secret to a long life involves a positive attitude and peaceful demeanor, avoiding conflict. The record for oldest person ever remains with Jeanne Calment at 122 years.
