From the author of THE PERFECT STORM & WAR comes a book about why men miss war why Londoners missed the Blitz & what we can all learn from American Indian captives who refused to go home Tribe is a look at post-traumatic stress disorder & the challenges veterans face returning to society Using his background in anthropology Sebastian Junger argues that the problem lies not with vets or with the trauma they've suffered but with the society to which they are trying to return One of the most puzzling things about veterans who experience PTSD is that the majority never even saw combat-and yet they feel deeply alienated & out of place back home The reason may lie in our natural inclination as a species to live in groups of thirty to fifty people who are entirely reliant on one another for safety comfort & a sense of meaning in short the life of a soldier It is one of the ironies of the modern age that as affluence rises in a society so do rates of suicide depression & of course PTSD In a wealthy society people don't need to cooperate with one another so they often lead much lonelier lives that lead to psychological distress There is a way for modern society to reverse this trend however & studying how veterans react to coming home may provide a clue to how to do it But it won't be easy
