Remembering a photo-journalist

No one life is more valuable than another. Yet people have talked extensively about two photo-journalists who recently died while covering the fight for Libya. Indeed, there is something haunting, deeply saddening about someone dying while trying to cover the horrors of war. In an effort to bring the carnage to light, photo-journalists are not immune to the dangers of their work. Although this is off the topic of medicine, it is certainly a reminder of our mortality and the sacrifices involved in dangerous work; this moving tribute to Tim Hetherington struck me especially hard.
