Cannes Lions 2014 Winner / Nature's Garden - Hepalive (Maruri Grey)

Scientists discovered that the liver produces a substance called Glucocorticoid that regulates your emotions. So the organ that controls your feelings is your liver, not your heart, despite what you've been led to believe. Maruri Grey Ecuador re-recorded famous songs that used the word heart, and replaced it with the word liver as a radio campaign for Hepalive, a liver supplement. (http://grey.com/)
