That sounds real nice till they're on a ventilator, feeding tube, catheter, and have ALS. Froze in their own body unable to move, except blink for yes and no and defecate on themselves. They need to be lifted several time a day and rotated to keep them free of bed sores, have you ever used a Hoyer lift. If the electricity goes out, the generator fires up and till then, you have to bag them or they'll die. I moved to be closer so we could do that for 3 years, they had no money or outside support.
My mother in law was 94 and lived alone, walking in the park one day and died the next. My parents died an honorable death, the best money can buy. Society can only do so much when everyone in the house has to work. Try it and get back with me.
