Across the world, research has found that almost 182 million of us are addicted to using the web.
And as gadgets becomes more popular, the trend is leading to the emergence of new technology-related disorders.
The latest has been dubbed NetBrain - and sufferers show increased levels of narcissism, poor attention span and fear of missing out (FOMO).
These people are also more likely to gamble online and regularly use social networks and gaming sites and apps.
Unsurprisingly, people with smartphones are almost three times more likely to score highly for NetBrain than those without.
