Picture the scene.
It’s a typical IOM conference in a hotel in a distant city. You walk into the elevator, press the button to go outside for some fresh air and after the elevator doors close, everything suddenly turns to black.
You cannot even press the emergency button in the elevator as there is no electricity. You fend off a growing sense of panic and wonder how long you will be stuck in what now feels like a sauna suspended in midair that’s completely dark.
