This is incredible -- a New Jersey woman celebrated her 110th birthday this week.

Mary Gibson was born on June 6, 1909, when William Taft was president. She celebrated with family, friends, and cake at Peace Care in Jersey City, where she's lived for the last six years.

Turning 110 this week gives Gibson the status known as supercentenarian.

When asked for her secret to longevity, she told WABC-TV it's been nothing more than eating healthy and exercising. Ya don't say?

Happy Birthday, Mary!
