Well, Daisy - may you never know what hit you if it does. My friend that died recently was standing up one second, and gone the next when his a-fib flipped into a non-perfusing rhythm. He never knew what hit him - not even a whimper. His next move would have been to drive home - that could have been a real mess. I still prefer the idea of passing quietly in my sleep - no chance of inadvertently causing a traffic accident. So, Daisy, if that's how you end up going, may you be asleep to start with, and never know a thing. I hope you have a good back up plan in place for your husband's care, just in case he outlasts you.
