Mike,
As a heart attack survivor myself, I feel more than a little empathy for your situation. Sorry to hear about your family history, but as you say modern medicine is truly miraculous. Hang in there, and I am sure you will make a full recovery and soon be back on the golf course soon.
I was truly surprised to read this as you give the appearance of being the picture of health. I blame the year you spent in New York.
Regards, best wishes, prayers, and thanks for all the Dixie Cups.
