Happiness - online puzzles

In psychology, happiness is a mental or emotional state of well-being which can be defined by, among others, positive or pleasant emotions ranging from contentment to intense joy. Happy mental states may reflect judgements by a person about their overall well-being.

Since the 1960s, happiness research has been conducted in a wide variety of scientific disciplines, including gerontology, social psychology, clinical and medical research and happiness economics.

In philosophy, happiness is translated from the Greek concept of eudaimonia, and refers to the good life, or flourishing, as opposed to an emotion.
