Um, retiring to a cruise ship is my plan. If I am generating enough from my withdrawal rate to afford it when I am a senior citizen.
I will be single, no children, and without close family. I am scared of becoming old and having a house I can't take care of and losing the ability to drive, too. When you end up with very limited mobility, a lack of social interaction, that's when people start to seem to go downhill, etc. I am scared of my world becoming very small, with no one to help care for me.
I love the idea of the built-in socialization, activities, food, travel, and relationships with staff and other long-term cruisers who can help "watch out" for an old senior citizen lady. Sounds way better than assisted living or a nursing home to me.
