All I can say after having been there done that in having been brought back from a major stroke that no thoughts were had at the time and next time around thats the way I want it. Although the family was called in after I was brought back I apparently woke up cussing and swearing and my wife said that was when she knew I was going to be OK. Just a year or so later I watched my wife suffer through a few weeks before her passing with incurable cancer and that was hell for both her and me so I am very much in favor of the ability to 'end it quickly' if one wishes. So far despite years of relatively minor arthritic pain which is now gradually reducing my mobility I have not reached the point of 'pulling the plug', not that we generally have much choice or say in that moment.
