Can you imagine a better place to have a heart attack than with a bunch of people who are trained CPR and O2 providers?
Sorry pops...I took off part of the message I left a couple days ago. I think I was a bit harsh. I don't believe that he would have lived either way...maybe if he had his heart attack above water in a hospital...but who knows. I think only God could answer that question.
I think you should do what you feel comfortable doing. It's a bad idea to do anything related to diving that makes you uncomfortable...that's when you make mistakes. I know Mike was comfortable with what he was doing that day, or he would not have done it. I think it was just his time. I can't think of any other reason.
Don't hesitate to take the advanced class unless you get into it and become uncomfortable. It can only make you a better/safer diver. I think that if you feel uncomfortable diving in general, it may not be a good idea to take the Adv. class (or maybe even to dive anymore at all). But if you are somewhat at ease, it will only make you feel more comfortable and in control of your underwater situation.
Try not to psych yourself out...diving is a fun and safe sport. It's just best to keep it within reason and not do anything you are not trained to do. That even goes for your confidence in what your instructor has taught you...if you feel you have not learned everything you need to know to be safe, you should go back to your LDS and tell them you need more instruction from a different instructor. I've had/seen BAD instructors before. It may just be a matter of finding a teacher who is better at teaching you. Everyone is different!
Lastly, I would remind you, it's a good idea to make sure your in decent shape...your general health (especially fat content) affects your ability to off-gas. In Mike's situation, I think it was a matter of bad or unexistant monitoring of his cardiovascular system by his physician. He had been under a doctor's care as recently as a year ago for pains in his chest...it was determined to be a 'separated rib', or something to that effect. Question your doctors diagnoses in situations such as this! and...
Dive! Dive! Dive!
My 2 cents...
