Around 75% of the world's population, approximately 4 billion people, don't have an address. Take a country like Mongolia, with a largely nomadic population, where street names and postcodes can be few and far between. But that could all be changing thanks to just three words. Mongolia's Postal Service was the first in the world to sign up to What3Words, an idea from a British former music executive fed up of bands and equipment constantly getting lost.

So is this small island nation set to be the first in the world to equalise pay?Presenter: India Rakusen Reporter: William KremerImage: Illustration of two Icelandic people / Credit: BBC

It looks like the set of Game of Thrones. Once a year Wolin in Poland hosts a huge Viking festival - with a twist.
