According to the China Daily, there’s a new epidemic in China: sore thumbs:

The mobile phone has brought a communications revolution to China, but doctors point out it is also causing a health problem – with the thumb.

In particular, the popularity of text messaging – known as “thumb culture” – is being blamed for the new phenomenon.

Because of instant delivery and low charges, text messages have rapidly become one of the most popular means of communication among young people….

But young people are now paying for their messaging mania.

I wonder if Japanese kids went through this?
