I am curious about the technology behind this since the sense of smell is one of the most befuddling to science. But as complex and complicated as it is you know bad breath when you smell it. Unless it’s your own. Hence the brutal nature of halitosis. You just don’t know when your breath should be bottled for use in chemical warfare due to acclimatization. I knew a girl whose breath was so toxic it filled my entire car when she rode in it. Needless to say we never got beyond the "nice to meet you" phase. This gadget is supposed to be able to give you a signal whether you should go in for the smooch or not. It provides five ratings: Kiss me, Possible, Maybe, Risky, and Never. |via BoingBoing|
