Having a living will and other directive legal documents isn't just for the elderly. Because unexpected events and illnesses can happen at any age, it is important to have your wishes in writing. These documents communicate for you when you aren't able to do so yourself -- if you are in a coma for example.
Living wills contain information such as "do not resuscitate" directions or information about preferences regarding respirators or tube feeding. For some, it includes compliance with religious traditions or special burial directions in the event the person passes on.
