The Wonder Woman costume she wore at her birthday "party" was a gift from her friends, who say she is a real life superhero.

So what's her secret to living a long, healthy life?

"Just keep busy, I guess," Cotter replied.

In fact, she's been busy for years. In 1930, Cotter helped her high-school win the state swim championship, she taught swimming to children into her 60s, and helped rescue sea turtles in her 90s.
