Picture the scene. You're on holiday and intend to go for a swim in a nearby reservoir. You pull out your phone for a selfie to make sure everyone knows you're having a lovely time, but you fumble the handset and it falls into the water.
Irritating, embarrassing, and it might even cause you some serious logistical difficulties. But it's not the end of the world, is it? Most of us would be able to move on and enjoy our holiday one way or another.
