Caroline Paul is a firefighter who doesn't even own a bright red bathing suit, though she's often mistaken for her identical twin sister, Alexandra, late of "Baywatch."

"I could be coming off a fire truck and someone will say, `Hey, you're that girl from that `Baywatch' show," Caroline Paul, 34, told Entertainment Weekly.Her sister played Lt. Stephanie Holden, David Hasselhoff's former boss on "Baywatch." But it's fire that fascinates Caroline.

She is an eight-year veteran of the San Francisco Fire Department and the author of "Fighting Fire," a behind-the-flames account of her job.

"If there's a fire, I want to be there," said Paul. "Maybe because in being so close to death, I think I understand what it means to be truly alive."
