Are you addicted to the Internet? You might be able to blame your genes. Scientists say they’ve found a link between a toxic relationship with the Web and a genetic quirk that also plays a role in nicotine addiction. Researchers at the University of Bonn in Germany interviewed 843 people about their online habits. Of them, 132 showed signs of an unhealthy relationship with the Internet — all of their thoughts revolved around it and their sense of wellbeing was shaken if they couldn’t go online. By comparing the genes of the two groups, the researchers found the subset of likely Internet addicts more often carried a mutation the CHRNA4 gene, which is typically linked to nicotine addiction.
