War Photography and photography for social Change

There is a great read on war photographers and the after affects of said wars I stumbled on over at Mantle Thought . I have always dreamed of doing War photography, social change photography or just plain documentary photography. It sounds very glamorous, see the world, meet interesting people and experience new things. When I look at these photos, however, I feel like I might actually want to do war photos... Its not until I am faced gruesome reality that I take a second to stop and think about it.
