You responded while I was editing my prior post.
I've had one family member die of alzheimers, and three family members die after being pulled from life support (two after a stroke, one after a cerebral hemmhorage). I can tell you with first hand authority there that they are by no means similar. But like I said: if, and/or when a person with alzheimer's gets to the point there the cognitive portion of their brain is dead, then that's a decision that the surviging family must make.
As for Obamacare, the OP isn't about Obamacare. Despite the fact that the "death panel" claim is a myth, I oppose Obamacare anyway.
For me and mine, my elderly mother has stated very clearly to me and her other children that she does not wish to have any lifesaving or lifesustaining procedures done on her. No heart paddles, no feeding tube, no respirator. That's her choice to make, and my obligation to enforce, should that day come. I likewise have told my wife that I do not want any lifesaving procedures done. Many folks here would consider that murder by their conversations here.
There seems to be a concensus here that a person I should be allowed to decide whether they want to be artificially sustained if they were ever to become brain dead, including allowing the spouse to carry out those wishes. It's therefore amusing that one person can make that statement and not have their Christianity questioned, while another can make the same statement and be accused of beign "pro-death". That double-standard is totally ridiculous.
