 And now, we would like to open it for discussion. Would anyone like to raise a question? Yes, you have shown us that there is a high usage of smartphones in Hong Kong. Is it also a global trend? Thank you for your question. Yes, it's a global trend. There is data showing that smartphones have become more popular in many societies. The research results from an international marketing company, there were more than 960 million smartphones sold in 2003 all around the world. The company has estimated the sales of smartphones will reach 1 billion in 2014. So, we believe that the smartphone users will rise globally. Does that answer your question? Yes, thank you. Okay, is there any other questions? You have mentioned in your presentation that radiation from phones may damage body structures. There was a recent news story that reported that the blue violet light from smartphones may cause blindness. So, is there any way that we can use the phone safely? That's a good question. Well, there is certainly a safe way to use smartphones. That is, don't overuse them. Doctors and opticians have said that the eyes problem resulting from smartphones is caused by not blinking enough and putting the smartphone too close to your eye. So, they have suggested that users should take regular breaks from using smartphones. Hold the device in your hand and keep the distance between your eyes and your phone less than 30 centimeters. Yes, there are all good points and there are two more easy things suggested by WHO experts that we can do to reduce the influence of radiation from phones on our body. First, we should use a wire or speaker when we are using the phone. And this keeps the phone away from our head. Second, we can keep the phone in our back instead of putting it in the pocket of our clothes. This will reduce the radiation that we may receive from the phone. Have I answered your question? Yes, that's fine. Thank you.
