The 'Are You Addicted to the Internet?' infographic is a revealing look at your brain when surfing the web.
This graph documents how many people are on the web and what age group surfs the most. It even examines the ratio of men to women, and it turns out that there are more females on the Internet than males.
Some other interesting facts are that four out of five people in the US are on the Internet, and about a decade ago it was only half the population. Another random tidbit is how more nonsmokers and non-drinkers are on the web. Perhaps this is due to the fact they don't have to take so many breaks when surfing various sites.
