Checking your mobile phone while having a drink with friends or taking a call over dinner, isn't just annoying for those around you - it could be making you unhappy.
A study found that we spend more than a quarter of our leisure time distracted, with everything from barking dogs to road works disturbing concentration.And mobile phones were the worst offenders.
The gadgets not only proved the biggest attention-grabber –they also seemed to affect people's happiness.
The University College London researchers are not sure why this is but say it is possible that we feel upset that are unable to control the urge to fiddle with our phone.
In contrast, we realise we have no control over external distractions like road works and so they affect us less.
Whatever the reason, they said that it is clear that we live in an 'age of distractions'.
The survey of 2,000 people by fashion technology firm Mous, suggests almost half of our biggest irritations are technology-related.
We hope these findings will help highlight how important it is to carve out time where attention is undivided and to enjoy spending quality time together.'
