Good but disheartening article about living wills. How about a medical power of attorney?
I printed out two copies of the "will to live", but haven't gone over it yet. Would a medical power of attorney, naming someone who is not my legal next of kin, be good enough? I have personal reasons for excluding my oldest daughter.
It gives your trusted DPOA the right to make decisions instead of you.
Depending on your level of paranoia, it is probably not a good idea to use an heir.
The other missing ingredient, that everyone must have, is a doctor who is working for YOU, rather than the government or an insurance company.
