Millions of people are using cell phones today. In many places, it is actually considered unusual not to use one. In many countries, cell phones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected.
The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.
On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a travelling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree. What is it that makes mobile phones potentially harmful? The answer is radiation. High- tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.
As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often

✽ Means of transport:
Flying car is a future means of transport and I think in the future, most people wil travel by flying cars. It will have 2 wings so it can fly as a plane. It will not be as big as a plane its speed will be higher than any other vehicles now. I think flying cars will use solar power with super thin batteries. It will look strange. Flying car will have a few functions but it will be fast. There are 500 people in it. Besides, it will avoid the traffic. A flying car will be used for air transport but it can also be used on the road. It can travel 500 kph. Learning to drive this transport is very easy. People can control it by touching on the control panel or they can set it in the automated control system. It can be use both the city and in the countryside. I think flying car is the convenient transport for people to travel everywhere in the world and I believe it's the most popular transport in the future because it's an environmentally friendly transport and people can drive faster by using flying cars.
