In any event, no one should have the right to murder another human being, "vegetative" or not.
We are keeping an organism alive only at this time.
Not at all. Given your line of faulty reasoning, we should disconnect all those who are getting feeding intravenously. Is that what you think is "humane"?
Just because one has not heard of a term (such as vegetative state) does not mean the condition does not exist. Can you name all the organisms in the ocean? Do they not exist because you have not heard about them?
Some people on feeding tubes have requested death rather than lying in bed countless years, but the law forbids that. If you had ALS(Lou Gehrig's Disease) and you were facing spending your final year of life with your mental capacities in tact, but your body jello, would you want that? Is death a worse alternative? Is living with God a worse alternative?
Exactly. My grandmother had to be fed like this for months and months and we were urged to stop feeding her by "experts" at the hospital. With rehab, she regained her swallow and went on to much more fruitful life.
How many of us have no trouble coming up with dozens of instances where the "experts" failed miserably?
