I believe this section is about trying to put some clear definition around the concept of “grievous” and “irremediable”. It does introduce new terminology, such as “incurable in illness”, and “advance stage of irreversible decline”, and things like “reasonable foreseeable death”.
I'm wondering if you feel that it does successfully narrowly enough define the concept of “grievous” and “irremediable“, or do you think this section is useful at all?
