A woman stationed at the Marine Corps base in San Diego in the 1940s celebrated her 100th birthday on Sunday.

A celebration was held for Gladys Ruth Gallivan at the Veterans Village.

At age 26, Gallivan joined the Marines as a private during World War II and was one of the first women to join during the "Free a Man to Fight" campaign.

A tea party was held for Gallivan, and the Women Marines Association said she received cards from all around the world.

Gallivan said the celebration was touching.

"I cannot believe it,” Gallivan said. “It’s amazing to think that somebody would do this just for me. Really is, well, it’s fabulous."

Gallivan said the trick to looking younger is to not think about the age.
