Despite his extraordinary accomplishment, Walter Orthmann's advice for those looking for a long and fulfilling professional life are surprisingly routine: do what you love and stay away from junk food.

According to local media, Orthmann started on the factory floor of a company now known as RenauxView, which produces fabrics. Soon after, he moved to administration, eventually becoming a sales manager.

To keep sharp, he stretches daily and assiduously watches his diet.

"I really avoid salt and sugar," he said. "I avoid things that hurt your intestines. I avoid Coke and other sodas. I only consume things that are good for you. That really helps your body to be strong forever."
