Post-Traumatic Stress Disorder

Upon learning about post-traumatic stress disorder, I felt very sad. It is terrible that the people who are fighting for our rights and our country not only put their lives on the line, but also have to live with the pain and suffering even when they are back home from the war. I wonder why some people who are in the war, or endure terrible situations experience PTSD and others do not. The virtual reality therapy that was featured in the video that we watched in class amazed me. I was shocked that by virtually reliving the situation over and over again, the victims were able to cope with the pain more easily and quickly.
