I say most of us do get a say. That’s what those DNR forms are supposed to represent, at least that is my understanding.
I know all plans can be changed by the will of God, but He often seems to allow us many choices before that final moment comes down.
We are given a one way choice. We can say ‘yes’ to death on the forms, but we can’t say ‘yes’ to life on them. So you can either chose to die, or you can choose to let the hospital make an economic decision.
