New York’s oldest person turns 112 — and shares secret to her longevity: ‘That’s why I’m living’

She’s one for the ages.

New York’s oldest person turned 112 this week — and said the secret to longevity is never getting married or having kids.

Louise Jean Signore — a 4-foot-5 firecracker from the Bronx’s Co-op City — said she has lived a long, happy life because she’s smoke-free, booze-free and free of a spouse and children.

“That’s why I am living. That’s why I am OK because I didn’t get married … no marriage, no children. I’d rather be single,” she told The Post on Friday, two days after her historic birthday.

“When you are married you have a lot of trouble.”

The spunky supercentenarian also credited “good living” for her long run, saying, “I don’t smoke, I don’t drink.”

Signore, who worked for the MTA for 39 years , including as an administrative assistant, celebrated her birthday Wednesday with homemade pasta from her nephew, along with cake and visits from friends, she said.

She also got what any person lucky enough to live to 112 could use — a lottery ticket.

Signore’s neighbor, Francis Perkins, bought her a $5 scratch-off ticket and said his pal was thrilled to win $50.

“She was so happy,” Perkins said.

Signore was born in 1912 — back when a copy of the New York Post cost 3 cents — and has lived through everything from the Great Depression to the Titanic’s demise.

Back in her heyday, the world was a less dangerous place, she said.

“Things were OK. It was during the Second World War. My brothers were in the war. They all came home,” she said.

“It was safer then. Not today … today it’s not safe,” she said.

The feisty fogey also advised younger generations to listen to older and wiser folks, like their moms and dads.

“What they should do is listen to their parents, listen to what their parents tell them,” she urged.

Signore was born in Harlem in 1912 as the eldest of five siblings and the daughter of Italian immigrants. She moved with her family to The Bronx at age 12.

She attended Richmond High School and had a passion for ballroom dancing and swimming.

All of her siblings have since died.

“I’m the oldest, and I am the only one left,” she said.

Signore is listed as New York’s oldest resident and America’s eighth oldest person , according to longeviquest.com , which tracks and verifies the world’s oldest people.

By contrast, the oldest person on the planet is five years her senior — 117-year-old María Branyas Morera of Spain.

Over the years, Signore said she has stayed active, maintained a strict routine and listened to her body over the years, all factors in her longevity.

“You know, I’m systematic. I do the same thing every day at the same time. I don’t change. If I take a nap at 8 o’clock, I don’t change, I take a nap,” she said.

“It’s my body. Nobody tells me what to do. I do what I think is best. It works.”

In June 2022, she fell and broke her hip and later underwent the first surgery of her life but has since recovered with the help of light exercise.

“When she can’t go outside, she uses her walker to walk back and forth in the hallway to get her exercise,” Perkins said. “It’s a privilege to know her.”

Signore said she also eats right with a healthy diet packed full of Italian food, and usually has a light breakfast.

“I don’t have much, I have eggs, I have bread with jam and tea, but that’s it. No coffee, I don’t drink coffee,” she said.

Signore now lives a simple life, enjoying TV sitcoms such as “The Jeffersons,” going outside and watching neighborhood kids play ball.

“I enjoy when it’s a nice day and the aides take me out. … I am too old to do anything special,” she said. “I’m just living.”

She also is keeping charge of her life.

“The interview is over,” she told The Post after a chat — and asked her aide to take her back upstairs.
