I think living wills are a great idea because they allow people to express and make known their wishes while they are still able to make and express their decisions. Living wills allow people to control their medical treatment and the extent to which the doctors should go in order to preserve their lives.
Yes, living wills are of importance. It is a tough situation because most of us don't want to consider the chance of becoming ill or near death. The living wills do provide instructions as to the type of care one may want to receive, and of who should oversee these decisions.
