103 Year-Old 'Wonder Woman' Reveals Her Secret To Life, Celebrates Birthday Volunteering At Senior Center
October 20, 2015
Mary Cotter just celebrated her 103rd birthday at the Montclair Senior Center, California, where she's been volunteering for the last 25 years.

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.
