Happy International Happiness Day!
Happiness may mean something different to everyone, but the founder of the United Nations International Day of Happiness believes it is a "fundamental human right" for all.
The day, celebrated on 20 March, was created by United Nations special adviser Jayme Illien. He said happiness is a "goal for al human beings".
