Restrain children from internet

My son miserably failed in two entrance exams that he wrote in the beginning of this academic year.
I knew the reason. He didn’t get even one single hour during the one month he got for preparation. He was busy with internet.
Another girl whom I closely know almost broke her four-year-old marriage only because her husband lost his cool over her spending too much of time on internet and caring less her 3-year-old child.
I can hear people swearing when their servers get slow or power supply is abruptly interrupted.
There are boys who would prefer more online games than food and sleep.
And they are called internet addicts.
According to reports, web addiction will soon be classified as a mental illness.  The newly revised Diagnostic and Statistical Manual of Mental Health Disorders (DSM-V) for 2013 has already added “Internet Use Disorder” in their list.
According to experts, unfettered and unhealthy use of internet should be a serious cause of concern.
According to Steve Williams, a passionate supporter of Lesbian, Gay, Bisexual and Trans (LGBT) rights, human rights, animal welfare and health care reform, Internet Use Disorder (IUD) presents itself in many ways that are standard for addiction. Symptoms include but are not limited to:
A “preoccupation” with the Internet or Internet gaming
Withdrawal symptoms when no longer able to access the Internet
An increasing tolerance to the stimuli which means they require more time and greater Internet use in order to achieve the same high
A loss of other interests
Using the Internet to replace or make up for a lack of human relationships
Failed attempts at quitting their Internet overuse
Using the Internet as a tool to escape or improve general depression and sadness.

A published novelist, poet and a scriptwriter for computer games, film and web serials, Steve Williams says this abnormality is rare in adults, but the children who are suffering from IUD have been known to become angry and violent when their supply of Internet time is interrupted.
Recent studies have shown that there are physical changes in the brains of adolescents suffering from online gaming addiction — and these changes are remarkably similar to those presented in the brains of adolescent drug users.

Let’s limit our children’s online activities. Why should our kids suffer from mental maladies?
