Supplying someone with food and water is hardly "extraordinary means". Although gastrostomy tubes are not exactly a "natural" way of feeding someone, their use in many cases is for the mutual benefit and convenience of caretaker and patient. If it would require over an hour per meal to feed a patient by mouth and a g-tube can do the job in under five minutes, that does not mean the g-tube constitutes "heroic measures". It certainly does not justify discontinuing g-tube feedings while simultaneously withholding oral sustenance.
The people who want to starve/dehydrate Terri are seeking to do so not because she's dying, but because she isn't. Actually, the fact that Terri has survived as long as she has suggests that she is (or at least until recently was) in surprisingly good health. Although she is at present unable to communicate effectively, the fact that she's survived as well as she has suggests to me that she has more 'brainpower' than Felos et al. want to acknowledge.

Supercat, you are EXACTLY CORRECT!!! I couldn't have said it better.
That's a real good way to put it.
