Would you risk your life to take a glorious selfie with the world at your feet?
Maybe not. But some daredevils such as Russian tourists Alexander Remnev and his friends became online celebs after their selfies went viral. They took photos of themselves as well as sweeping views of Dubai from the top of some skyscrapers there.
Some daring shots were taken when they were perched on precarious spots on towering buildings. They didn't seem to suffer from vertigo, like acrobats and extreme-sport enthusiasts with nerves of steel.
