elder parent wants to live with another elder (same age, no dementia but physically weak and mildly forgetful); elder parent does not want to bathe (house smells like urine). Elder parent is living with another family member, but wants to go to their own home, does not want outside help. Is it more merciful (and legally preferred/required) to let the elder parent live in their own home in dirty/smelly clothes, or better to tell them that a previous medical power of attorney has taken away their right to live alone? When the 2 elders live alone, they eat salty foods and do not take medicine, preferring vitamins. When is that "right to choose" taken away?
