Advanced directives?

Just wondering what the people think on here. Would you like to have everything done to save your life? And would this decision be the same if you were making it for a loved one?

I'm 30 and healthy, so yea, I'd like everything done. But if I was in an awful wreck and on a ventilator for weeks and no signs of getting off, then pull the plug.
And, if I was 70 and had cancer and knew I only had a few months anyway, if I have a heart attack, just let me go.

Obviously, it depends on the circumstances.

If I were involved in an accident of some sort and had a less than 50% chance of survival, or survival with very poor or no quality of life, then I would want to go on and die. But if, based on the physician's judgement, I would make a full recovery, or return to at least 80% functionality, then I would want all possible done. I have made a living will with that information disclosed, as well. I don't want my family wasting time and arguing about how to treat my illness. My decision will have been made, and they would have to honor it. And I am but 31 years old, and in great health, but you never know...

Advanced directives are a kindness to your family and very helpful to your doctor. It lets people know what you prefer in the event of the need for heroic measures due to illness or injury.

It depends on what's wrong with me. I've already let my family know that if my quality of life isn't going to be the same that I"m accustomed to, then to just let me go. And if I had to make this decision for a loved one, it would definitely be the same. No one likes to go through the pain of seeing someone they love in pain or vice versa, you don't want to be the cause of someone else's pain. Its just easier if you have already written out and notarized what you want when its time to make a decision regarding your life. Be sure to make copies and to inform all of your family.

I'm an ICU nurse. No point in even writing it out. If you have family present and even 1 person disagrees with decisions being made, the doctor will do the most conservative thing ignoring what your advance directives say. Doctors these days are too afraid of being sued by the surviving family. Spend your time talking to your family extensively about what you do want/ don't want done.
