I'm watching with interest the ways our lives are changing as a result of social media. I'm a user so I understand the benefits, but as a parent and an employer I can't help but be concerned. Have you ever sat at an airport or a cafe and watched people on their phones and tablets? It won't be long before we start to look like our Neanderthal forebears with our necks poking forward and our shoulders increasingly rounded.
You probably think I sound like your father, but a new study by New York spine surgeon Kenneth Hansraj suggests that looking down at your mobile is the equivalent of placing a 60-pound weight - or an average-sized 8-year-old - on your neck.
They say the average American spends two hours and 42 minutes a day on their mobile. With that kind of weight-equivalent hanging off the neck, will there be serious implications for bodies in the future?
But I'm more interested in the psychological impact of social media. New Zealand has already seen the worrisome effects of Tinder with the death of Warriena Wright while holidaying on the Gold Coast. There have also been suicides attributed to social media bullying. Although these are the extremes, I was disturbed to hear of the experiences of a younger friend of mine whom I rate highly in intelligence and EQ, with Happn, an app that competes with Tinder.
Happn uses location data to show where you have passed a person who also uses Happn, at what time you passed them and how many times you have passed them. If silly enough, the person can choose to tell you where they work.
