Humour

Humour (Commonwealth English) or humor (American English) is the tendency of experiences to provoke laughter and provide amusement. The term derives from the humoral medicine of the ancient Greeks, which taught that the balance of fluids in the human body, known as "humours" (Latin: humor, "body fluid"), controlled human health and emotion.

People of all ages and cultures respond to humour. Most people can experience humour—be amused, smile or laugh at something funny (such as a pun or joke)—and thus are considered to have a sense of humour. The hypothetical person lacking a sense of humour would likely find the behaviour to be inexplicable, strange, or even irrational. Though ultimately decided by subjective personal taste, the extent to which a person finds something humorous depends on a host of variables, including geographical location, culture, maturity, level of education, intelligence and context. For example, young children may favour slapstick such as Punch and Judy puppet shows or cartoons such as Tom and Jerry or Looney Tunes, whose physical nature makes it accessible to them. By contrast, more sophisticated forms of humour such as satire require an understanding of its social meaning and context, and thus tend to appeal to a more mature audience.

Theories

Many theories exist about what humour is and what social function it serves. The prevailing types of theories attempting to account for the existence of humour include psychological theories, the vast majority of which consider humour-induced behaviour to be very healthy; spiritual theories, which may, for instance, consider humour to be a "gift from God"; and theories which consider humour to be an unexplainable mystery, very much like a mystical experience.
