A Living Will allows you to make decisions for three different instances: terminal illness, persistent unconsciousness, and severe and permanent mental impairment. You will need to determine your preferences for:
Life support
Tube feeding
CPR
Intervening illness
You may also list whether or not you would like to be on organ donor, if you have any feelings about specific treatments, and how symptoms, such as pain, should be controlled. A Living Will also allows you to designate a temporary guardian for your children in the event of an emergency.
