New York’s oldest person turned 112 last week, and she shared her secret to a long, fulfilling life. Louise Jean Signore, a 4-foot-5 Italian-American, was born in Harlem in 1912 and moved to the Bronx at age 12, where she still lives today. She worked for the Metropolitan Transportation Authority (MTA) for 39 years. The eldest of five siblings, she’s the only one still living.

When asked what her secret to longevity is, she said: “No marriage and no children.” “That’s why I am living. That’s why I am OK because I didn’t get married,” she told the New York Post this week. “I’d rather be single. When you are married, you have a lot of trouble.”
