It's good to know that 83% of us DON'T suffer from "PTS disorder." Almost all of Hanoi Boi's "Winter Soldiers" suffered from it even though only one of them went to Vietnam as a rear echelon.... Many of the "Winter Soldiers" developed PTS after listening to "war stories" told by returning Vietnam veterans.
The hack that wrote this "implied" that several hundred thousand new veterans have PST, he didn't say they did. Most of these writers suffer from it and have never left the states.
