20 ways the net can ruin your life
When John Flexman ticked a box on networking site LinkedIn to register his interest in 'career opportunities', it cost him his €80,000-a-year job.
Now the 34-year-old British executive has gained notoriety as the first person in the UK to bring a case for constructive dismissal after being sacked for posting his CV on LinkedIn.
"The internet and social media are important tools for helping to elevate you up the career ladder, but equally they can have the complete opposite affect," says career coach Paul Mullen.
Indeed, Flexman is not the first nor is he likely to be the last to have his career suffer due to his extracurricular online activities.
A group of male employees at the accounting giant PricewaterhouseCoopers had their career prospects take a blow in 2010 after being caught forwarding a "top 10" email list of the most attractive female employees in the office.
And the future doesn't look too bright for the 16-year-old employee of US pizza chain Papa John's who was sacked last week after referring to a customer Minhee Cho as "lady chinky eyes" on a receipt. Cho then posted the receipt on Twitter.
In fact, one-in-20 participants in a UK study said they had either been fired or reprimanded for sending inappropriate messages in work.
But far from just ruining our careers, many believe the internet is destroying our social lives, health and well-being.
We have become so obsessive about checking our email and social networking accounts that some of us experience "phantom" vibrations, where we mistakenly believe their phone is buzzing in our pockets, according to research by the British Psychological Society.
We also can suffer withdrawal symptoms, if the results of a study of 200 University of Maryland students who gave up online media to see how they would cope is to believed.
When asked how they felt during the brief disconnection from their online lives, they described frantic cravings, anxiety and jitters, which mirrored those typical of people going through withdrawal from drugs or alcohol.
And the internet could be having an even more detrimental impact on our brains. Just last week a study found that internet addiction is linked to changes in the brain similar to those who are addicted to alcohol, cocaine and cannabis.
So before you text, surf or update your Facebook profile, sit back and read the 20 ways that the internet could be ruining your life . . . before it is too late.

It is violating your privacy
Apple was left red-faced after its iPhones were discovered to be collecting and storing location data, while Google's street-mapping camera cars were caught collecting data on every domestic WiFi network they passed.

It can falsely accuse you
When software engineer Lakshmana Kailash K was jailed for 50 days for posting defamatory pictures on Facebook, there was just one problem -- he was innocent.

While moaning about your boss is a time-honoured tradition, the internet has made it a more precarious pastime. Clerical assistant Aoife O'Mahony was fired for bitching about her boss on Facebook. The Employment Appeals Tribunal ruled in December her dismissal from PJF Insurances for calling her boss a "bitch" had not been unfair.
It makes you make more mistakes
Predictive text messaging changes the way children's brains work and makes them more likely to make mistakes, according to scientists in a Melbourne University. This makes them more prone to impulsive and thoughtless behaviour.
