1) Pain, often pain management becomes a much bigger issue than going all out fighting vehemently to prolong your life by a few more days/weeks/months. Its hard to understand what chronic pain does to you and your mind unless you or a close loved one goes through it. Often pain management also aligns with 'slipping gently into the night'.

2) Incentives, hospitals are in the business of making money and they's gladly run marginally useful tests and medicines until they max out whatever coffers they can. as I see its not long before the ethical/common sense minded providers get overpowered by the money making machine and give in. as it is perhaps you are not aware there was a study that concluded most (IIRC 75%) of a persons healthcare expenses happen in last 18months of their lifes. just ask yourselves this, would you rather give your inheritance to your kids & grandkids or some hospital trying to maximize profits by promising you random treatment that increases you life by a few months? ultimately this should be your decision to make but there should be strong protections around the options providers can present to you.
