DALLAS - At age 75, Ernestine Shepherd still has something to prove.
"I enjoy letting people know age is just a number," she said.
In the world of body building, Shepherd has become an international star. She is in the Guinness Book of World Records for being the oldest body builder in the world.
"If there were an anti-aging pill, you would really name it 'exercise,'" Shepherd said.
She was the first guest at a fitness expo in Dallas this week, and News 8's George Riba stopped by to see Shepherd's message to the crowd.
