In a career that has spanned many decades, Kenneth Curzon has done everything from managing service centers at car dealerships to acting as Smokey the Bear for the U.S. Forest Service. He's also a World War II veteran who witnessed D-Day from the beaches of Normandy as a member of the British forces.

But for the past 24 years he has been running the parking services at Scripps Memorial Hospital, which sees more than 3,000 vehicles come in and out every day.

His work day starts at 6:15 a.m. so he can ensure all of the equipment, including the parking lot gates and ticket machines, is working before he moves on to other duties, like preparing financial and operations reports.

"I'm not sure that I've ever beat him in in the morning," said hospital Chief Executive Officer Gary Fybel. "He's always here bright and early."

The extra pay has given Curzon enough cushion that he has given some of his retirement savings away to friends, family and charities.

While he has worked longer than many of his coworkers have been alive, he said he has no plans to stop.

"If they came to me and said I need to step aside then I would do that, but I would probably look for another job," he said.
