Just a suggestion folks......
I work at a VA hospital, and we have several long term care units. Weekly, there are issues involving living wills, and advance directives. I'm certainly no expert, but I would offer a few views.....
advance directives obviously are those wishes that you want or don't want this or that treatment, or device used if you can't make the decision at that time. Do not overlook creating a durable power of attorney for health care. You can appoint anyone, not just relatives. I went one step further and had my immediate family members sign a separate agreement NOT to attempt to alter the contents of the advance directives I've set forth.
I've seen many a living will challenged and changed by family members, when the "end of life" draws near.
Hopefully, this Schiavo case will educate a few folks and prevent this situation in the future.
Links abound online.... here's an example :
