Broken ribs, broken wrists, broken arms, broken back. For Phil Harris, that's standard fare trolling the Alaskan seas for Alaskan and snow crab, a lifestyle chronicled in Discovery Channel's most successful series to date, "Deadliest Catch."

"Everything in my body aches," says the low-key Harris.

"It takes me 20 minutes to get out of bed every morning. I've had Mar- ines come on the boat. They say this makes boot camp look like a picnic."

The name "Deadliest Catch" is no exaggeration. Pro fishermen have one of the highest mortality rates of any profession. In fact, one of Harris' workers once fell out of his boat and died. Tumbling into the chilly Alaskan waters is pretty much a death sentence.

The trade-off: Fishing is lucrative. You can earn well into the six figures — if you can survive the lifestyle.

Harris has, often clearing $500,000 a year. He owns a huge lakeside home in Seattle, two Harleys and a $100,000 Z06 Corvette.

He gets five months off a year. As captain of the Cornelia Marie for 17 years, the 51-year-old ranks in the top five in volume among the 70 boats that vie for crab.

And while Harris no longer has to do the heavy lifting (his two sons help him out), he is hardly immune to injury. In a scene to be shown later this season, a monster wave pummeled his boat this past January, causing him to fall out of his bunk. He punctured a lung and broke his ribs. But his conditioned worsened after a blood clot dislodged from a leg and traveled to his heart.

Harris almost died from a pulmonary aneurysm, and the remains of the clot are still life-threatening.

"I'm eating massive amounts of medicine" to break down the clot, he says. "I take them every day and pray."

The show draws nearly 3.5 million viewers every Tuesday in its fourth season. (In 22 airings the week of April 21, the show accumulated an audience of 19.7 million people.) "Deadliest Catch" has spawned a raft of similar macho shows such as "Ax Men" and "Ice Road Truckers," both on the History Channel.

"Ice road truckers?" Harris said, with derision. "I don't want to take away from those guys, but what they do is puny compared to what we do."

Indeed, he still takes pride in his work, enjoys the open seas — for now.

"I'll retire the day I get scared," he said. "I don't know when that'll be. Could be anytime!"
