German Boffins are developing a mobile phone that will alert users when their breath is bad or they are particularly smelly.

Siemens Mobile said that a new breed of phone will have a tiny chip that measures less than a millimetre to detect unpleasant odours.

It will examine the air in the immediate vicinity for anything from bad breath and alcohol to atmospheric gas levels. She didn’t say what the phone would do if it found you too smelly, it might ring you or send out a high pitched scream that shouts bad breath to anyone who might want to get close to you.

The reason for the heavy research is because some people take smelling good rather seriously. However the moment you get in a London underground tube, in rush hour, in the middle of summer so many phone warnings will go off it will be impossible for you to hear your self think.
