No one should have to. Most of us have decades to prepare for our old age, it’s unfair to place that burden on your children.
That being said, I love my parents, and even if they are not expecting us to nurse them, I am prepared to hire a nurse to take care of them if needed.
I also want to avoid cleaning doodoos if possible.
It’s not that great anyway. Your local toilet will surreptitiously grab and analyze your poop, dispose of it so you don’t need to flush, and have the remote toilet extrude an identical copy someone else has to flush.
