Elizabeth Francis of Houston was born in 1909, and celebrated her 110th birthday Saturday.

She credits her faith in God for longevity in this life.

What are the details?

"Blessing of the Lord," she explained to KTRK-TV. "He's the one keeping me. That's why I'm living."

Ethel Harrison, Francis' granddaughter, says that her family is nothing short of blessed to have Francis in their lives.

"It's really special, because she's been able to watch and see all of her grandchildren grow up and be a part of their lives," Harrison told the station.

The station reported that Francis, who was born in Louisiana, is still as sharp as a tack and is healthy to boot.

Francis and her family celebrated the milestone on Saturday, along with Houston Mayor Sylvester Turner.

The centenarian donned a sparkly "Happy Birthday" crown to mark the occasion.

What else?

On Thursday, WCBS-TV reported another birthday milestone: New York City resident Louise Signore, who turned 107 this week.

The secret to her long life? Signore says she's lived as long as she's had because she never married.

"I think the secret of 107 [is] I never got married," she explained. "My sister says, 'I wish I never got married!'"

Signore said that she's also maintained a healthy diet and continues to exercise despite her age. Signore, who has lived in the Bronx since the age of 14, said that her age doesn't slow her down.

"I dance. I still do a little dancing," she said. "After my lunch, I will play bingo, so I had a full day."

Signore insisted that Italian food and a lack of sugar has helped.

"Italian food," she said. "Italian food is very good for you. I was brought up with very good food. No soda, no cake."
