Human behavior refers to the array of every  physical action and observable emotion associated with individuals, as well as the human race as a whole. While specific traits of one's personality and temperament may be more consistent, other behaviors will change as one moves from birth through adulthood. In addition to being dictated by age and genetics, behavior, driven in part by thoughts and feelings, is an insight into individual psyche, revealing among other things attitudes and values. Social behavior, a subset of human behavior, study the considerable influence of social interaction and culture. Additional influences include ethics, encircling, authority, rapport, hypnosis, persuasion and coercion.

"Human Behaviour" is an alternative song with lyrics reflecting upon human nature and emotion from a non-human animal's point of view. The song and music video were inspired by British broadcaster and naturalist David Attenborough.
