Trauma is not just the result of major disasters. It does not happen to only some people. An undercurrent of trauma runs through ordinary life, shot through as it is with the poignancy of impermanence. I like to say that if we are not suffering from post-traumatic stress disorder, we are suffering from pre-traumatic stress disorder. There is no way to be alive without being conscious of the potential for disaster. One way or another, death (and its cousins: old age, illness, accidents, separation and loss) hangs over all of us. Nobody is immune. Our world is unstable and unpredictable, and operates, to a great degree and despite incredible scientific advancement, outside our ability to control it.
