How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.

The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.

The toothbrush will be able to teach you to brush right (don’t forget the insides of the teeth!) and make sure you’re brushing long enough. “It’s kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.

The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart but also fun,” Several says.

Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.

The company says the Kolibree will go on sale this summer, for $99 to $199, developing on features. The U.S. is the first target market.

Serval says that one day, it’ll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.

In my opinion, classical music is a bit like mushrooms! You don’t see the link? Let me explain. When I was younger, I didn’t like mushrooms. They had a horrible texture(质地)and no taste at all, and I used to pick them out of every dish in which my mum tired to hide them. But gradually, as I got older, my view changed. I started to enjoy mushrooms-flavoured things like soups and sauces, and eventually I found I could eat mushrooms without grimacing(痛苦的表情). And now I even quite enjoy them! So my mum’s prediction that I would “grow into them” was proved quite correct.

Similarly, I always thought of classical music as this boring genre(类型)that only boring grown-ups liked. Whenever my parents played it in the car, I would count down the minutes until we could change it to my preferred genre: pop. But while at university, I found that calming orchestral music was just the thing for library revision playlists---it had no lyrics to stop me concentrating on my study, and the pieces tended to be very long; perfect for long work sessions!

Recently, my developing relationship with classical music reached a new level when I voluntarily chose to go to a ballet. Admittedly, it was the dancing that originally attracted me, but once there I thoroughly enjoyed the music too. It was The Nutcracker, and I was surprised by just how much of music I recognized! The Dance of the Sugar Plum Fairy, The Russian Dance, The Waltz of the Flowers—they all sounded familiar. I didn’t know how I knew them, I just knew that I did! And I loved them. My parents would be proud.
