NEW YORK (Reuters) - A woman from New York City, who celebrates her 100-year-old birthday in a center for the elderly, said the secret to her longevity was not marrying and staying single.

Louise Seignor was born in Harlem in 1912 and has lived in the Bronx since she moved to her home at the age of 14, where she continues to live alone, maintain her business and have good relations with her community.

The Newsweek newspaper, quoting American media, said that Signor did not need a walking crutch, that she was shopping herself and was only taking blood pressure medicine, preferring to eat Italian food.

The newspaper said earlier research confirmed that singles live less than married couples and that single men die from eight to 17 years younger than married, while single women die from seven to 15 years less than married. However, these data did not apply to Signor.
