Did they have brain activity? Did they have any ability to move their bodies?
I'm sorry to hear about those children and bless you for taking care of them.
But I've seen the most ridiculous comparisons to PVS made known to man. Some people have said that maybe we'll start killing off the Christopher Reeves or the people on dialysis.
There is simply no comparison to those examples and PVS. None.
They had no ability to move themselves. Their heads hung when you picked them up. half of the food they were fed came back out of their mouths. But that was before tubes were stuck into people's stomachs for convenience's sake. If they would've lived today and had tubes so it would be easier and less messy to feed them, that would have been deemed keeping them alive by "artificial means", and their lives would have been in danger.
