It used to be that young mothers coo-cooed at their babies as they pushed them along or tucked their blankets in or squeezed their little cheeks as those small children carefully observed their mothers' expressions, learning things faster than at any other time in their coming lives, appreciating the immeasurable value of eye contact.
It used to be that workmates talked to each other on their breaks - perhaps joking or solving work problems together or talking about family, sport or popular films or simply the weather.
It used to be that people kept moving on public staircases or when simply walking down the street and when people crossed those streets they put safety first, looking this way and that, paying heed.
It used to be that elected representatives in political chambers paid attention to what was being said in the here and now, perhaps responding with questions or points of their own, fully engaged.
It used to be that in restaurants, couples conversed between courses, confiding in each other and perhaps making remarks about the service or other diners. And it was the same in pubs - it was the socialising that mattered most.
It used to be that people read books and magazines and letters they had received in the post and sought pub quiz answers in their heads
But now - what are people doing instead?
They are looking down at their smartphones.
Never up, always down.
