No pain, no gain?

That doesn’t seem to be entirely the case for centenarian Matilda Curcia of San Diego, Calif., who credits her longevity in part to imbibing a beer and three potato chips every evening.

Well, maybe more than three chips, she told local TV station KNSD with a grin.

"I've experienced good health," Gurcia said. "I do my exercises every day. And have my beer. Eat my potato chips. That's about all."

According to the station, Matilda and a neighbor, who preferred to just use her first name, Mickey, turned 100 years within days of each other and recently celebrated with a party with their families. Blue, gold and hot pink balloons shaped as "100" were among the decorations.

The women, who live four doors from one another, said they moved to the neighborhood around the same time almost 50 years ago. They said they like to take walks and ride their bikes.

Mickey, a nurse, served in World War II in Australia, New Guinea and the Philippines, KNSD reported.

"I’d been a general duty nurse for a long time and then World War II started. And I signed up right away to go overseas," she said. "And I went to different parts where they were really fighting."
