  Age-inappropriate Content Age-inappropriatecontent is perhaps the biggest disadvantage of the Internet. The worst being underage material, which is largely rampant in the deeper parts of the web. It is the lack of control over the distribution and unrestricted access of inappropriate material, that is detrimental to children. All that parents can do, is lock harmful sites and monitor the sites viewed by their children.

  Social Isolation, Obesity,and Depression The link between obesity and the Internet is rather easy to understand. The more one sits in front of the computer, the lesser one exercises. At the end of the longish list of physical and emotional maladies, is depression. Since all problems are so deeply linked with one another and with the Internet, it isn't uncommon for people to be afflicted with multiple issues. Recent studies and research have gone deep enough to actually differentiate between compulsive Internet use and excessive Internet use. Furthermore, thanks to smartphones, holding a simple face-to- face conversation seems out of the ordinary as compared to chatting online.
