Today is the International Day of Happiness with the UN saying the pursuit of happiness is a fundamental human goal.

UN General Secretary Ban Ki-moon said: "Happiness may have different meanings for different people.

"But we can all agree that it means working to end conflict, poverty and other unfortunate conditions in which so many of our fellow human beings live."

The event was initiated in 2012 as the UN recognised "the relevance of happiness and well-being as universal goals and aspirations in the lives of human beings".
