Dove Portugal "Real beauty beats" by Black Ship

Real love wins in a Dove experiment that asks men to assess a series of images of women.

The men were shown images of beautiful female models and asked to explain how they felt about the women's appearance. They answered with words that superficially praised the models' physical characteristics.

To the men's surprise, they were then shown images of their wives, sisters and daughters. There was a considerable increase in participants' heart rate, and their vocabulary changed to express their admiration and love for their family members.

The film was viewed more than one million times during its first week on YouTube.
