 I didn't really know what that was, but we're trained in emergency medicine. Then we rotate through the operating room and so forth. A couple of years later, I find myself attached to the 7th Marines with a medical pack and a gun in my holster. Long story short, 71, I got home, thank God, and had the most bizarre symptoms you have ever seen. I worked with Dr. Everett Hughes at USC Medical School, who one day mentioned to me, Doug, did you eat raw fish?
