When should I talk to my aunt about end of life decisions?

End of Life. When people ask me the 'when' question, that usually means that it needs to be done now. Asking about these important issues when the loved one is able to express them is the most important thing that people can try to accomplish. Resuscitation issues, medical power of attorney issues, finanical decision-making are all important to discuss.
At any time. I think that the best time is when there is not an immediate crisis so that you can have a calm discussion about her wishes and thoughts about end of life.
