Again, I'll go back to the principles that we're talking about when mental illness is present, and that is the need for a very careful assessment to understand what is influencing the patient's decision-making process. It's not a question of making a value judgment on their decision but a question of evaluating the rationality of all of the pieces that are in the process going toward making the decision. That would need to be brought in at any point where someone is providing a directive. Again, if mental illness is present, then we think any decision needs to be properly evaluated.
I just want to clarify one point. I don't want my prior comments to be misconstrued as a suggestion that a psychiatrist needs to be involved in every decision. We were saying that when mental illness is present, a psychiatrist needs to be involved.
