Ulysses pact
（重定向自Ulysses contract）
A Ulysses pact or Ulysses contract is a freely made decision that is designed and intended to bind oneself in the future. The term is used in medicine, especially in reference to advance directives (also known as living wills), where there is some controversy over whether a decision made by a person in one state of health should be considered binding upon that person when he or she is in a markedly different, usually worse, state of health.
