Project:Nose
With a 40% smaller brain area that perceives odour when compared to females, the male olfaction is less sensitive on average. Nivea Men used this insight, and the scientific fact that men generally sweat more and can't smell their own sweat (males have approximately 9.2 million male brain cells versus 16.2 million female brain cells in the specific brain area governing our sense of smell), to present their revolutionary “Project:Nose,” the first smartphone app that can actually smell human sweat, specifically male human sweat.
