Three teenagers have posted what might be the ultimate selfie video, taken at the top of one of Hong Kong’s tallest skyscrapers that's 1,135 feet tall. Fox News says the videographer used a selfie stick tool and a wide angle lens on his camera to produce the video which has now been viewed more then 500,000 times on YouTube. Extreme selfies are taking off all over the world. Recently one man climbed the 124 foot Christ the Redeemer statue in Brazil and posted a picture after his climb. However, others haven’t been so lucky. A Polish couple recently fell off the edge of a cliff in Portugal while they were reportedly taking a selfie. In front of their children. Are so-called "extreme selfies" going too far?
