Know someone whose breath could peel the paint off a wall?

Then consider the OkaytoKiss – a device that gauges bad breath that was recently invented by scientists at Tel Aviv University.

The pocket-sized breath test measures malodorous bacteria in your mouth. A blue result suggests you need a toothbrush. But if it’s clear, you’re okay-to-kiss.

Until recently, scientists believed that only one population of bacteria (the Gram-negative ones) break down the proteins in the mouth that produce foul odor. But Professor Mel Rosenberg and Dr. Nir Sterer have discovered another kind of bacteria that also foster bad breath.

This enzymatic activity, present in saliva, serves as the basis for the OkaytoKiss device, which is awaiting patent approval.

Rosenberg is an international authority on bad breath and is about to release a book based on 20 years of research into the area. The new book is called - get this – Save Your Breath.

So what do you think EcoSpeak readers? Can you imagine a market for the OkaytoKiss device? Think it could replace a brutally honest friend?
