Are smartphones killing memories?

The habit of taking photographs, usually with our phones, of anything and everything is everywhere - instead of enjoying things or engaging in them, there is a growing habit just of photographing them.

It is as if first hand events are not real unless we have a photo, and can experience them second hand.

When, for example, the Queen recently opened the BBC's Broadcasting House, she could hardly be seen for all the people holding up their phones.
