I don't have to 'foresee every situation' to know I do not wish to live by feeding tube. I cannot think a circumstance where I would want that. Remember that these durable powers do not come into play unless you are already incapable of making your own decisions.
It is still true that, whether you wish to be artificially maintained, or whether you wish (as I do) not to be artificially maintained, it is most important to write your wishes down.
The government is clearly becoming very active in enforcing its will upon helpless people. It would be much better to 'arm' family members with weapons to protect you against your 'friendly' government.
I had always thought well of Gilmore, but had never heard this story of Hugh Finn. I am appalled that after the family resolved all their differences, poor Hugh had to face an onslaught from his state government and some unrelated woman who thought she knew best.
But Mrs. Finn, you can bet your last dollar, would not have removed the feeding tube of one of the children, if one of them had not recovered from the accident. She would not have done that to her "blood" relative. She did it to her husband without blinking for the $! She let it ride until HE became a financial liability.
