From the school of products that remind you of your inadequacies (and hopefully prompt you to buy stuff) comes this phone that measures the smelliness of your breath.
All you do is hold the handset up to your mouth, blow briefly on a sensor at one end, and in ten seconds it rates your halitosis on a scale of one to ten – based on the sulphur content in your breath.
The phone, which is still a prototype and is not expected to come out until 2009 at the earliest, also measures heart rate, body fat, and can be used as a pedometre. (You put it in your pocket and it senses your leg movement, so the theory goes.)
Perhaps it should have an inbuilt garlic sensor too, for checking whether you're up to talking to people after a strongly seasoned meal. And maybe the second-generation models can have a breath-freshening spray built in? No? Just a thought.
