I did not already know some of the things you pointed out, like the fact that her husband would not let anyone feed her.
I do still hold my opinion about being kept alive by machines. One thing is for SURE about this case and that is the importance of everyone having a LIVING WILL.
In 1992, a failure to put anything to the contrary in writing was an unambiguous affirmation of one's desire to be given food and water. It's only retroactively that any sort of oral declaration from that era has been deemed to mean anything.
You should also be aware that a feeding tube is not a machine. It is a tool, but not a machine. Huge difference. Before you make out a living will, be very certain that you understand explicitly what each and every item means. They are not the panacea that the mainstream media is trying to get us to believe that they are.
Here's a link that will help you to understand some of the trickery involved in living wills. Please make sure to read it all, as it is long. Bookmark it if you have to.
