Why do journalists volunteer to cover war?

Snip from a Boston Globe op-ed by Michael Socolow:

Like most soldiers, many combat journalists are young and have few family commitments. It is with the arrival of marriage and children that many journalists are forced to decide whether risking one's life is justified. This can lead to tension within news organizations; editorial assignments carry the risk of becoming life-and-death decisions. ABC News recently lost a lawsuit in Britain when correspondent Richard Gizbert alleged his contract was not renewed because he refused a "voluntary" assignment to Iraq. Gizbert, a seasoned war reporter, is no coward. He informed his superiors that family responsibilities changed his willingness to accept the work. Shortly thereafter he was let go.

Gizbert's prudence, however, is not a virtue prized among war reporters. The job requires accepting enormous risk and living life as a gamble. So why do so many volunteer? One explanation rarely surfaces in this discussion. That's the powerful, almost narcotic pull of experiencing life at its most intense. In the war zone, senses are primed, awareness is heightened, and profound bonds of friendship are indelibly formed. Sharing drinks and stories of narrow escapes, the combat journalist finds a community supportive of the addictive adrenaline habit that infects them all.
