Technology has done a lot to improve our lives, but it has also been responsible for the meteoric rise in popularity of the "selfie" - a photograph of yourself taken by yourself.
Back when cameras were cameras and phones were hallway appliances and we didn't need profile pictures there wasn't much call for taking photos of yourself. Why bother when you could just look in the mirror or ask someone else to take the photo?
Our columnist Brian Holden wrote in yesterday's paper about selfie sticks - extendable rods to which you attach your smartphone to take a picture of yourself. He argued that it's better to get someone else to take the shot - that way you get to meet strangers, plus you get to avoid the tell-tale outstretched arm and pole.
But selfies are, in their own way, an art form that only works when you know the subject is the artist.
These days they're usually taken to be shared, not sit in an album. "Look - I was here!"
