Top Israeli stinks boffins have developed a small breathalyser-style test device which can accurately tell a user if he or she has bad breath, putting an end to the stress and uncertainty of the unreliable blow-in-your-hand method. The new test is dubbed “OkayToKiss”. OkayToKiss comes to us from the fertile brain of Professor Mel Rosenberg of Tel Aviv university, described the “international authority on the diagnosis and treatment of bad breath”. Prof Rosenberg is, needless to say, editor of the Journal of Breath Research. He is also the inventor of the apparently well-known “two-phase mouthwash”.
