What is longevity secret of world's oldest man?

Have you ever wondered what it takes to live for over a century?

This question crosses every mind. To get an answer to this question, meet John Alfred Tinniswood.

John is a 111-year-old Englishman. He has recently been recognized as the world's oldest man by Guinness World Records.

He attributes his remarkable longevity to a blend of luck, moderation, and a cherished tradition of fish and chips every Friday.

Tinniswood, who was born in Liverpool on August 26, 1912, just months after the Titanic sank, has lived through significant historical events, including two World Wars. He served in the British Army Pay Corps during World War II.

Now residing in a care home in Southport, northwest England, Tinniswood was presented with his Guinness World Records certificate this past Thursday. His recognition follows the passing of the previous record-holders, Juan Vicente Pérez of Venezuela, who lived to be 114, and Gisaburo Sonobe of Japan, who passed away on March 31 at the age of 112.

In his long life, Tinniswood, a retired accountant and great-grandfather, has always believed in the importance of moderation. He has never been a smoker, rarely drinks, and doesn't follow any special diet, save for his weekly fish and chip supper.

Tinniswood shared his philosophy with Guinness World Records, saying, "If you drink too much or you eat too much or you walk too much — if you do too much of anything — you’re going to suffer eventually."

But in the end, he believes it all comes down to luck. "It's pure luck. You either live long or you live short, and you can’t do much about it."

Meanwhile, the title of the world's oldest living person is held by 117-year-old Maria Branyas Morera of Spain.
