The document discusses an advertisement for Kitkat that uses a salmon fish as a symbol for people who work excessively without breaks. The ad takes a documentary style to tell the factual story of a salmon's working life as a way to emphasize the importance of not being a "salmon" and instead taking breaks, like one would with a Kitkat bar. The target audience includes children and working people aged 18 to 30, as Kitkat makes for a good substitute for tea and coffee breaks and its chocolate is known to provide health benefits.
