103-Year Old Woman Cosplays as Wonder Woman

It's no wonder that people think of Mary Cotter as a Wonder Woman. Her 103rd birthday party was held at the Montclair Senior Center in Montclair, California. Ms. Cotter was busy the entire time. She's been volunteering there for 25 years and didn't see her own birthday as an excuse to slack off. She lives alone and drives her own car, so she has a mind to do what she wants at her own party. ABC News 7 reports:

Cotter says the secret to her longevity has to do with her daily routine. And it's pretty obvious if you stop and watch her for a moment.

"Just keep busy I guess," she said with a shrug.

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