Katharina Kink started working as a waitress at the Zum Goldenen Tal restaurant near Weyarn in southern Germany when she was 16. More than 75 years later, now aged 91, she still works there.

In 1939, the Nazis introduced a law requiring all unmarried women under 25 to work on farm or help a large family for 12 months. Kink went to work for the Huber family who owned the restaurant in the village of Naring.

After the war, her host family asked her to stay on to care for their children and help in the restaurant. Seventy-five years later, she's still there.

Known to the regulars as "Kathi", she says the restaurant is her life, and she intends to carry on working there as long as she can. She had to have a knee operation a few years ago, but was soon donning her Dirndl again. "All the nurses were amazed at how quickly I was able to walk again," she recalls.

The 91-year-old serves food, helps to peel potatoes every morning, and she regularly launders the restaurant's many tablecloths.

In 1977, she started wearing a pedometer, because guests were curious about how far she had to run between the counter, dining room and beer garden. Since then she has covered a whopping 81,000km – that's more than twice around the world.
