Whatever you’ve done in your life, you’ll never be as cool as Mary Cotter, a 103-year-old, who recently celebrated her birthday at the Montclair Senior Center, California, dressed as Wonder Woman. Cotter has been volunteering at the center for the last 25 years, where she’s famous as the “barmaid”, as she serves drinks to the residents.

According to ABC7 Cotter has a long career in volunteering with kids and animals. When asked about the special occasion of the birthday, Cotter said, “I don’t know, just another day went by.”
