That's similar to how I look at it. I'll at least let them try. My cousin had an awful experience giving birth 6-7 years ago. She died on the table, but they shocked her and brought her back. She hasn't had any serious health issues in the years since. To think that if the roles were reversed with her and my friend, then we'd have been mourning her for almost a decade. I cannot wrap my head around that.
This also sums up my feelings. I'll let them shock me to bring me back, but I have no desire to be in a vegetative state. I've seen how tough that is on family members when there isn't a written document about the patient's wishes about what to do in that state.
