Bhutan is the only country in the world to rank Gross National Happiness (GNH) above GDP. And now Denmark just got a whole museum devoted to the pursuit of happiness. Located in the basement of a late 18th-century building on the pastel-coloured historic Old Town of Copenhagen, the Happiness Museum was created with the goal of bringing literal happiness to people&rsquos lives while reminding its visitors the value and need to feel good.
