The amount of powerful drugs required to control the pain that many of these unfortunate people have renders them unable to interact with their loved ones because it decreases their level of consciousness so much. It also suppresses their respirations to the degree that they are struggling to breathe...often they are just barely breathing...like a fish out of water. They become incontinent of urine, they become incontinent of stool. They can't even manage their own secretions in their mouth...much less eat or drink anything.
