I was assigned to Phan Rang RVN in 1965-66 which was a major AF Base that may or may not have stored agent orange on the base. Regardless of the storage location if you were in RVN you were exposed and when there is no history of diabetes in your family for four generations I don't think Type 2 diabetes can be labeled as genetic. I am 6'4" and weigh 203 lbs so obesity is not a factor, I never scored less than 275 out of 300 on the AFPT I ran 7 miles a day (every day of the year) did 80 push-ups, 90-100 sit-ups every morning until my heart attack. I ate what the Army provided from 1961 until 1967 and then when I married I maintained a healthy diet, I did smoke moderately less than a pack a day but I quit in 1985 and my heart attack was in 1996. I was grounded in 1985 for Ischemia, less than ten years after I left the service and 19 years after returning from RVN. My point is when I separated in August of 85 I was given a complete flight physical and for every year after I received a class two flight physical and passed until 1985 when they detected an abnormality and said I had in the past a minor incident. No way was this age, diet, smoking, obesity, or sedentary life style related it happened to fast without any family history. Agent Orange? Yeah!
