Some of my colleagues have probably seen the movie Flags of our Fathers by Clint Eastwood. In the opening segment of the movie they show an elderly gentleman and his wife in bed, and he's shaking because he's remembering an event that happened in battle at Iwo Jima 60 years ago.
When I talk to some folks, they say that post-traumatic stress doesn't necessarily happen right away. It can happen many years later. An event that happens now is somehow buried, and then years later it comes out and you suffer from that. Is this a common occurrence you've seen in your studies?
