I have one last thing to add. Dr. Vince correct me if I am wrong. I have been told that the #1 indicator for an upcoming heart event ( I'm choosing my words carefully) Is excessive fatigue for no apparent reason. I think about that all the time. I had an experience with a guy who worked for me, we knew his family history was not good. I sent him to the doctors on 2 occasions when he experienced some symptoms that concerned me. The only reason he went was I threatened to call his wife. He was more afraid of her then he was of me. Both turned out to be non events. At the end of the day he went to work for another Superintendent. Died on the way home from work one day of a massive heart attack. He had complained to his family and his Superintendent that he was really tired.... for no apparent reason..
