$this->bbcode_second_pass_quote('KaiserJeep', 'C')orrect. You need to enter retirement with the house paid off, no mortgage, and already owning at least one durable automobile, likely to last the same couple of decades that you will last. I like Jeeps, myself.
Beyond that, you need to own some additional real estate in the form of fertile and unused land. That's my plan, anyways. Desireable real estate that people want to own, is in limited supply, they quit making it a few billion years ago. It can be used as living space, or if times get tough as they did in the Great Depression, a few acres of crops, a woodlot, a well, and a few chickens is a time-honored survival scheme.
I personally believe that real estate is a good hedge against currency inflation. Perhaps you believe in gold or Bitcoins instead. Get it right, and your genes will persist upon the planet.
IOW, you "won" the Game of Life.
