living will: https://en.wikipedia.org/wiki/Advance_healthcare_directive
An advance healthcare directive, also known as living will, personal directive, advance directive, medical directive or advance decision, is a legal document in which a person specifies what actions should be taken for their health if they are no longer able to make decisions for themselves because of illness or incapacity. In the U.S. it has a legal status in itself, whereas in some countries it is legally persuasive without being a legal document.
