John Tinniswood was born on August 26, 1912, served in World War II, worked as an accountant for most of his life, and retired in 1972.
Tinniswood attributed his longevity to sheer luck, although he noted that his active lifestyle likely contributed as well.
“I don’t feel my age; I don’t worry about it. Probably that’s why I’ve lived so long,” Tinniswood stated in one of his interviews.
