PTSD is another diagnosis that I don't fully grasp. I don't know why some people can all experience the same event as a group, but some have long lasting psychological effects, while others in the same experience have no issues. It is something that piques my interest. I don't have any real theories or concrete ideas, but psychological resilience is difficult to quantify. Why can most people shake off a traumatic event while others are so severely affected. Being able to quantify who can and cannot endure traumatic events would be extremely beneficial to keep the vulnerable from being exposed to extreme scenarios. I know the prevalence of PTSD among veterans have a lot to do with medical benefits in relation to the VA, but there are definitely people that aren't pretending for disability benefits. My personal experience with veterans claiming PTSD have not been very positive. Many of the members claiming PTSD were full time FOB inhabitants and only experienced indirect fire. The vast majority that were in the field and engaged directly with directed fire combat were unaffected in any negative aspects. I traveled throughout all of Iraq for 18 mos in two separate deployments in early 2000 and again later in 2008. I have some bad experiences, but they simply don't occur to me, instead I have overwhelming positive memories of camaraderie and friendship and positive experiences with most of the Iraqi nationals. I guess it is just how different people process experiences and memories. Lord knows I have a lifetime of suppressed traumatic events, perhaps that is the key? I have a fairly traumatic upbringing that most would consider fairly negative, however it was normal for me and I don't dwell on the hardship, but remember the good times.
