It's a bit of a cliche that people are spending so much time on the internet these days that they are actually ignoring reality. However, there's quite a bit of truth to it.
Internet addiction is a huge problem in some countries, with numerous clinics being built to address the problem. And there are more and more stories of people ignoring their responsibilities offline. One of the most tragic is the case of a South Korean couple who were so involved with raising an online virtual baby that they let their real child die of neglect.
