If you thought there was a correlation between a partner's use of their smart phone into the early hours of the morning and an increase in their level of grumpiness in the morning you were right.

A new study, published in "Sleep Medicine", has found more than a third of us are waking up with "social jet-lag", a condition that manifests itself in much the same way as the more traditional form.
Researchers have found that when people use their devices within an hour of going to bed or going to sleep they disrupt their natural sleep patterns in the same way as if they had flown from one time zone into another.
Up to one third of all Australians, across almost all age groups, are regularly sleep deprived as a result.
While the study is alarming its findings shouldn't come as a surprise.
Levels of smart phone, tablet and computer usage have soared over the past 10 to 15 years. An estimated 2.67 billion people world wide are now signed up to growing number of social networks including Facebook, Twitter, Linked In, Instagram, Snapchat and WhatsApp.
Then, of course, there are the online sales and gambling sites which do a roaring trade 24-hours a day.
The trouble is that while all of these apps and programs are great things when used in moderation and, in many cases do have the ability to bring people together, help them to stay connected and make an active contribution to the quality of our lives, they also carry significant risk.
Because of their addictive nature devices, social media platforms and games sites can and do consume their users.
More and more of us are finding that instead of enhancing connections with the real world, friends and workmates, the cyberverse is actually isolating us from the things we should care most about.
Professor Katina Mitchell, writing in PC World in 2017, said social problems associated with device addiction included "sleep deprivation, anxiety, depression, diminished performance in either paid or academic work and issues with anger management.
"There are reports of men addicted to video games who cannot keep a 9-5 job," she said. "There are women suffering from depression and anxiety because they compare their online status with that of their peers, there are children who message on Instagram throughout the night, then there are those who are addicted to their work at the expense of all physical relationships around them."
None of this is good; especially when you consider a technology that didn't even exist two decades ago has now become almost totally pervasive.
As of this year almost eight in 10 of all Australians, regardless of age, now use social media. At least 40 per cent having taken a selfie, 40 per cent have posted food photos and 63 per cent of 18 to 29 year olds have been excited when one of their posts has received more likes than they expected.
This is an amazing transformation in behaviour patterns which will flow through to all aspects of our lives.
This technology, like every human invention since time began, can be used for either good or ill.
How we will respond to it depends on ourselves and ourselves alone.
