Thank you for that question. It's certainly a question that we've had lots of debate about as well.
In our document, we have actually come up with a definition. I could read it to you, but the essence of it is that “grievous” is serious or severe, and “irremediable” is not able to be put right or cured. We recognize that these are not medical terms. There is not a medical definition of these terms, and there's definitely a subjective component associated with them.
As we worked through this question, we realized that it is clearly a dialogue between the patient and the physician. There's also the issue of suffering. Patients are really the only ones who can account for how much suffering they have.
We recognize that this is a discussion between the physician and the patient, and hopefully, as in most cases in medicine, we'll come to a decision together through a dialogue and through understanding where the patient is coming from, with the physician giving his or her advice as well. A decision will be made jointly in that respect.
