Doomsday-proof House
Apparently, there are some rich folks who are scared of the not-so-rich people gunning for their wealth once the world economy collapses, or when the world suffers from a nuclear winter.
So what do the super-rich decide to do? To protect themselves, they’re apparently building Doomsday-proof luxury housing underground in some parts of the world. Guess outlandish wealth can also cause some paranoia as well.
