The people who work at one East Tennessee restaurant joke that everything is breaking down except the owner of Mama Mia's. She is 91 years old. "I'm not going to quit until I go bye-bye," Lottie O'Brien said with a laugh. She's baked bread in a particular oven since 1956 when she ran a bakery up north.

"We had that one in the bakery in New Jersey. When we moved, we transferred that down here," she said. "Down here" is Kingston in Roane County. O'Brien arrived here after a long journey across the world. "I was born in Germany. My mother had 13 children. Mother says 'work don't kill' and I'm still here," she said.
