SOUTHFIELD, Mich. (FOX 2) - Thelma Jones isn't letting her age stop her.
The 90-year-old from the east side of Detroit has earned her fifth-degree black belt in Isshinryu karate, and she plans to keep going.
"You mention Miss Jones, and they go, 'Oh I know Miss Jones, she's tough,'" said grandmaster Willie Adams.
Jones takes lessons from Adams, a 10th-degree black belt, three times a week at Southfield Martial Arts.
"It really does teach you to listen, behind you, in front, and be aware of all things," Jones said.
When she was 60, she used her karate skills to fight off robbers at a bus stop. Recently, she used what she has learned from karate to protect herself from a suspicious man following her, but with a different approach.
"I crossed the street back, and he came at me. So, I went into the liquor store and waited until he left," she said. "That was karate right there, that was using your brain. I didn't want to duke it out with him."
After 50 years of karate, Jones has some advice: "Take care of your body, take care of your mind, and think a situation through before you react."
Jones isn't the only older person at the dojo, either. Adams, who is 77, said many people are in their 70s.
"The retired, they come here to get in shape, builds up confidence, slow to anger," he said.
