According to an Ofcom study, 55 per cent of the UK say they won't use theirs while dining. There's even a group trend of stacking all phones on the table when sitting down for a meal, ensuring full attention on the moment.

Once again it depends on the situation – but generally asking or saying you're going on your phone is best. You don't want to be part of that couple in the restaurant sat in the dark and silence illuminated only by your phones, do you?

explanation: this shows that people always use their smartphones during special conversation with their loved ones. 

Explain:if there were no smartphones we would not miss the memories that is valuable to us.And now people are having a hard time to letting go of their phones or turning them.Back when computers was the thing,they could at least turn it off and enjoy life for a moment but now phones can be brought with us everywhere we go

Phubbing (phone snubbing) is a serious issue, with couples choosing to spend their time together staring at their phones rather than interacting with each other. This is merely the thin end of a very large wedge that could harm our ability to connect and communicate with other people face-to-face.

Later, a 2008 study published in Fertility and Sterility reported that high cell phone use was directly and significantly associated with a low sperm count and overall infertility in men.

Cell phones decrease the semen quality by decreasing the sperm count, motility, viability and normal morphology.

When Jeff Bezos launched Amazon in the mid-90s there were around 4,000 bookstores in America. Two decades later, number had been cut half, resulting in thousands of lost retail jobs. Amazon destroyed 27,000 jobs in 2012 alone. Now that Amazon has expanded beyond bookselling, it is squeezing jobs in every retail sector from clothing, electronics and toys to garden furniture and jewellery. This is bad for mankind because people would not have jobs, so they would not have enough money and they would not have enough to eat. On the other hand, the companies get richer, which means the poor get poorer while the rich get richer. This will then cause a lot of unhappiness and can lead to conflict because when the poor have no food to eat, they will get looked down upon.
