For some, $14k a month may be as much as an upper end assisted living facility would cost so as long as one was in good health.

I've heard over at cruise critic that there was one woman who spent years (over a decade) at sea until forced onto shore and into a care home. No sure if her name was Beatrice Muller or someone else. I heard she had either spent 4,000 days (or perhaps even a multiple of that) nearly continuously on ships.
