Phil I realize in some cases they do procedures to extend life but you are in essence prolonging it in a short term fashion. It might be 6 months or 20 years but the Dr.s try to prolong it the best they can. I always have been one that thinks in a severe illness esp. cancer the one being treated should get 2-4 opinions and ask for projected outcomes. if it is a terminal situation the patient may choose a less invasive procedure for quality rather than quantity of life. The reason being in some cases if someone us either in uncontrolled pain, or not conscious life may be worthless to them and their loved ones as opposed to more time interacting them (even if they are alive 6 weeks and not 6 months most of which suffering or comatose). I hope I made myself clear to you folks and not offensive, that was not my intent at all.....
