103-year-old dresses up like Wonder Woman to celebrate her birthday

Meet Mary Cotter, who is a real life Wonder Woman.

The 103- year-old recently celebrated her birthday at Montclair Senior Center, California. She has been also volunteering here for last 25 years.

On her birthday her friends brought her ‘Wonder Woman’ costume. She is fondly called ‘barmaid’ by the residents as she serves them tea and coffee.

What’s amazing about her is that, in her 60’s she was a swimming instructor for children and in her 90’s she use to help rescue turtles.
