I am 73 years old and I am an Australian Vietnam Veteran. After returning to Australia and being diagnosed as suffering from PTSD, I began to study engineering and I now have the suffix of OMIEAust. (Officer Member Institution Engineers Australia) after my name. The home-based studies proved beneficial in keeping my mind focussed on the positive. I would like to introduce my book about the Indochina Wars entitled "A Gracious Enemy".
