Did it ever occur to you that sticking a sharp object into a body and injecting, say, penicillin, is an un-natural act?
Penicillin helps the body heal itself.
It is my opinion what when the body cannot regain the function (as in a PVS patient who cannot re-learn chewing or swallowing), the feeding tube unnaturally extends *life* beyond God's purposes.
If that is my religious belief, should I be forced to accept a feeding tube? Should I be forced to allow doctors intubate my wife with a feeding tube?
