John Tinniswood, who held the title of world's oldest man for a period, passed away on Monday at the age of 112, as confirmed by his family to UK media outlets. He resided in a care facility in Southport, England, for his final years. The cause of death has not been publicly disclosed.

A statement from the family expressed that his last day was filled with love and music, and extended gratitude to the care home staff who looked after him for 13 years.

Born in Liverpool on August 26, 1912, Tinniswood never claimed any specific secret to his longevity. He believed it was simply luck, stating that lifespan is largely predetermined. He held the "Oldest Living Man" title after the passing of Juan Vicente Pérez of Venezuela in April 2024. Unlike some centenarians who attribute their long lives to specific diets or habits, Tinniswood followed no special regimen. He simply ate what he was given and enjoyed a traditional British meal of fish and chips every Friday.

He was also recognized as the world's oldest surviving male World War II veteran. Tinniswood practiced moderation throughout his life. He abstained from smoking and rarely consumed alcohol, believing that excess in any form would eventually lead to problems. Even on his 112th birthday, he reiterated his lack of any special secrets to his long life, attributing his active youth to frequent walks.
