FORT WORTH, Texas -- Elizabeth Sullivan of Forth Worth, Texas, says she has one doctor to thank for her long life: Dr. Pepper.

Sullivan told KTVT she fell in love with the soft drink's trademark "23 flavors" when she was in her 60s.

"Every doctor that sees me says, 'They’ll kill you,' but they die and I don’t. So there must be a mistake somewhere," she said.

For her 104th birthday, Sullivan was surprised with a Dr. Pepper-shaped caked and a gift basket straight from Larry Young, the CEO of Dr. Pepper  Snapple Group Inc.

“When you live to be 104 and still can talk to nice people, you deserve some Dr. Pepper, but I never expected this,” she told KTVT.
