Man thats some scary stuff. Glad you came through this one okay. Maybe it's enough of a wake up call that you will do whatever it is you need to do to stave off a more serious one.
My best friend, a Texan named Jimmy Reynolds, dropped absolutely dead of a massive coronary at the age of 52. He was standing at his grill in Houston barbequing for a party at his house. DOA. It really shook me up, and made me start thinking about my own ticker a bit.
