Most states allow an individual the right to refuse ongoing medical treatment or artificial life support in the event of a terminal illness or catastrophic medical condition, even if to do so might hasten the moment of the individual's death. Many people do not want to have their lives artificially preserved in the event of a terminal illness, if to do so would result in increased medical costs and an emotional burden on their family. The living will, or advance health care directive, specifically instructs physicians to withhold certain types of treatment or artificial life support at the request of the patient in such an instance.
Not all clients or patients desire to sign living wills, and this is each individual's choice. But, for those that do not want to have their lives artificially prolonged through the application of breathing apparatuses, pumps, intravenous food and hydration, and other medical devices the merely prolong the inevitable, the living will is the most humane, cost-effective and psychologically agreeable and comforting option, both for the patient and the patient's family.
