A Living Will is often confused with a Will. A Will leaves your property to whomever you want when you die.
A Living Will says what happens while you are dying. A Living Will expresses your wishes when you have a terminal condition, or are in a end-stage condition, or a vegetative state.
A properly written Living Will states your wishes regarding respiration, water and food, intensive care, and whether you want medication to help with pain, even if the medication hastens your death. A Living Will can also say whether you want to be resuscitated should your heart stop.
A Living Will is a crucial document for those who want to alleviate suffering at the end of life. Whether to have one is a personal and sometimes, religious decision.
