(1) is contemporaneously expressed by the older individual—

(A) either orally or in writing;

(B) with respect to a specific illness or injury that the older individual has at the time of the decision; and

(C) when the older individual is competent to make the decision;

(2) is set forth prior to the occurrence of the illness or injury in a living will, health care proxy, or other advance directive document that is validly executed and applied under State law; or

(3) may be unambiguously deduced from the older individual’s life history.
