There are threads here about the Jewish religion being against depriving someone of food and water.
I posted this yesterday at another thread:
"Here's from Rabbi Aryeh Spero:
"Long ago Jewish law made a distinction between withholding medication and special treatments from a patient as opposed to withholding food and water. Whereas there comes a time when we are no longer required to proactively employ heroic medicines and treatments to keep a non-functioning body operating, it is always necessary to continue feeding a patient."
You can find that at Human Events Online, today's version."
