THAT'S A VERY LONG TIME AND YOU MAY DIE FROM RETIRING. BUT YOU HAVE MORE TIME SO YOU WILL HAVE A 85%-100% CHANCE OF RESTORING THE WORLD! YOU SHALL BE THE PRESIDENT OF THE CONSTITUTION!
You made it to the end! Well done *claps*. You know a thing or two about zombie killin', and you know it's 'every man for himself'! I think you're ready if the zombies come you're way!
You actually WERE good enough to survive in this hellish world. Now... you just gotta' make it through 2 more cities, an airport, and a harbor to make it to the boat... so, uh... good luck with that. :D
