Good luck paying for all that care as living in these places isn't cheap. Of course I don't know your financial status, nor how far into the future you're talking about. But not everyone is going to have the opportunity to accumulate that wad-of-cash to glide smoothly into progressively more intensive levels of retirement/nursing home care.

One fellow I know was working in IT until his company was bought out and he found himself made redundant. As he had been working with what is colloquially known as "Dinosaur Technology", he was middle-aged and companies these days expect new employees to show up fully trained, he had difficulties finding another position. He eventually ended up driving a school bus for $60/day. 

Pretty hard to save at that salary level, eh?

Fortunately only about 10% of the population end up in nursing homes, so you may not end up there. 

And good luck committing suicide. Maybe the laws covering that will be loosened by then.
