When I was in high school there was no whatsapp, not much iphones and people where not depending on technology as they are now. It was a rare thing to see a kid 10 years or younger with iphone, ipad, blackberry etc. Actually, at that time it was mostly only business men who had smart phones.

 

  Nowadays, big and small, poor and rich, from almost every where in the world nearly everyone owns or at least knows how to use a smart phone. Our whole life is depeding on technology. Even babies know how to use IPad.
