According to a broadcast on Shenzhen satellite television, a Taiwanese man worn damaged the cartilage in his finger while playing mobile phone games.
The man would apparently play mobile games for hours and hours on end each day, swiping and tapping his phone. As a result, his hand is now injured, and he cannot behind his finger properly.
A doctor appeared in the news broadcast, confirming that this is supposedly 100 per cent possible. The doctor also gave an odd analogy about cartilage and rubber tires, explaining that you only get some much mileage. Or so much rubber. Or cartilage. Or something.
