Telephone mania has reached everyone. Very often you can meet 7-8 year old kids who are calling their friends with all their might.

Why do you still need a cell phone and who needs it more: parents or children?

A mobile phone is a means by which parents control their children, and thereby delay their growing up. “Children should be under control,” many parents believe and buy mobile phones for their kids, trying to calm their own fears.

Daniela Brancati, a child psychologist, states: “Parents fear every moment their child spends outside the home, they believe that their child may be in mortal danger, especially at school.”

Why does a child need a cell phone?

Children need a cell phone to feel like adults, independent and free. This increases their rating in the eyes of friends and peers, opening access to desirable communication, videos and games. Children believe that with the help of a mobile phone they gain independence. The doubt remains: under the control of cell phones, children do not become adults.

The real need to buy a cell phone for a child is a busy schedule of various additional activities, when it is difficult to coordinate actions.

Warn your child that it is better to carry it in a pocket or briefcase, without unnecessarily showing it to strangers or on the street.

Is a cellular (mobile) phone harmful?

Scientists have not yet come to a final opinion on this issue. It has been proven that a mobile phone (as well as other electrical devices) emits waves that, with prolonged exposure to the brain, can worsen health. However, the phone can cause significant harm to your child and cause hearing problems if the volume is not adjusted.

Having made a positive decision to buy a phone, you must understand that spending is just beginning. Children do not always understand what is paid and what is not. Good way out- ban paid services. You can apply for it at the office of your mobile operator. This will save your budget from various expenses on paid SMS services, mobile games and applications.

Each parent must decide whether their child needs a mobile phone or whether they can still do without this invention.

What is a smartphone for? Progress does not stand still, that is why it is progress. This is especially noticeable in production computer equipment and mobile phones. If recently we rejoiced at pagers and video recorders, which began to appear on the shelves of our, at that time still poor, stores, now you will not surprise anyone with either a cell phone or a cell phone. Any janitor on the street can now talk not only to his broom, but also to swear at a careless garbage truck driver over his cell phone.

Our ancestors would generally go crazy looking at how every second person walks down the street and talks to himself or points his finger at some glowing portrait frame.

What a long way to go. My mother was hospitalized a year ago, and I took her there e-book. Lying in the room with her was a Tatar granny, about 90 years old. At night, this same granny woke up and saw a terrible picture. My roommate (my mother) is sitting in bed, and her face is illuminated by a deathly pale light emanating from some door.

I don’t know what the poor, downtrodden grandmother thought, but she screamed so loudly that the whole hospital woke up. She decided that there was a stove on the bed, and my mother was sitting and looking into it. The most interesting thing is that this grandmother was not walking, but then she jumped out of the room and rushed along the entire corridor so that she was barely caught. On the second day, a joke circulated throughout the hospital that they tried to burn down the hospital at night.

Imagine what would happen to a person who has never even seen a TV and does not know what electricity is.

But even in our advanced times, not everyone knows what a smartphone is and what it is needed for.

For tourists A smartphone will help you navigate well in a foreign country or city and in translating unfamiliar words in a foreign language. You can also use your smartphone to film some tricky situation and quickly upload it to.

Some people just need a smartphone for antlers, to keep up with fashion.

I know people, mostly elderly, who have smartphones but don't even know what to do with them other than make calls. It’s just that the children decided to give a gift to their beloved old people, and the old people need these functions like a goat needs a button accordion.

For example, I don’t need a smartphone either, because I’m used to doing everything thoroughly and not on the run. And you decide for yourself why you need a smartphone.
