The world's oldest woman, Susannah Mushatt Jones, has lived a simple life; she never partied, drank or smoked, according to Business Insider.

Jones turned 115 years old on Wednesday making her one of the last living people born in the 1800s. She sticks to the same routine everyday where she eats her breakfast in her Brooklyn apartment then chews Doublemint gum. Most of her diet consists of fruit.

The supercentenarian is one of the 40 people recorded in the world to have lived past their 110th birthday.

Sleep is one of her biggest secrets to longevity. After she finishes her breakfast, Jones sleeps for most of the day. The 115-year-old, also known as Miss Jones, has had clean health records for decades, despite having glaucoma that took her left eye 15 years ago.

Nowadays, the woman mostly responds to family members.

Back in the days, she was a nanny for wealthy white families with whom she traveled the country. She never had children of her own but loved the ones she cared for.

When she graduated from high school in Alabama, she was accepted into the Tuskegee Institute's teaching program, but her family could not afford to send her there.

Throughout her life she cared for other children. Jones helped to send her nieces to college with her salary. She also funded education for a few students in Alabama so that a lack of money would not end their dreams of attending college as it did for her.

Jones had one birthday wish: to get a phone call from President Barack Obama, New York Daily News notes.

"She loves boys," said Myra Simpson, Jones' 40-year-old niece. The woman has 100 nieces and nephews and never married.

Her family is planning two birthday parties for her this year -- one public and the other private.

She is the third of 11 children and is the only one still living.
