If you think that people who pull the tube and other life saving equipment from their loved ones in hospitals all over the country are engaging in something you don't think should happen, work with your legislators to change the laws.
And be sure to tell your loved ones that you wish to be kept alive through artificial means, even if you have no cognitive ability, for an indefinite period of time. Make sure your wishes are well known, preferably in writing, and the hospital and ultimate nursing home will be happy to keep collecting money and keep you alive.
Already done on both accounts. Thanks for the advice.
