I would encourage you to ask that question of health care providers as they come before your committee. My sense from to what I've been hearing from people is that they prefer the language of “reasonably foreseeable” death, that it actually speaks to professional judgment better than, “Is this person going to die within six months?” It's actually a harder question for people to be able to ask if they have to put a time frame around it.
I would encourage you to continue to ask that, and if you hear differently, please let me know.
