Please be very careful as you go about the process of filing an advance directive. They are not the panacea that the media is making them out to be.
Thanks for the warning. I will be seeing a lawyer about it, and I've been thinking about it a lot. I know all the ways a lawyer can twist what seems to be a clear statement into something not even resembling its obvious meaning. I do have the advantage that my husband is NOT a Michael Schiavo, so I'm fairly certain that if I became unable to talk, he wouldn't be trying to get legal permission to murder me!
