Today marks a special birthday for a Bucks County woman.

Dorothy "Dot" LaFaw says her secret to reaching 100 is a combination of good genes and good habits.

"A hundred years - it doesn't seem possible - that I've really lived this long," said LaFaw, "I never smoke or drank. And another thing is I'm a positive person."

Born in Philadelphia and raised in Levittown, LaFaw still lives independently in Bristol. She does get support from LIFE St. Mary, a long-term care program designed to keep seniors out of nursing homes.

Erin Williams, manager of outreach at LIFE St. Mary's, says the program coordinates all aspects of healthcare for their members in order to help them live healthily and happily on their own.

LaFaw has a full schedule for her birthday, including one at the LIFE Center. The 100th birthday festivities will include a special performance from the Mummers.

She says she's thrilled to celebrate with friends and family at the historic King George Inn in Bristol.

"Two parties in two days! That's a lot for someone my age," said LaFaw, "but I like to have fun, so it's good."
