MOSCOW, RUSSIA - UNDATED: Max Polazov does press-ups from outside of a building 120 meters high in Moscow, Russia. Hanging by the tips of his toes with his entire body suspended hundreds of feet above Moscow certain death awaits this Russian youth if he loses concentration for just a moment. Going literally one step further than the US roof-toppers this Russian daredevil is demonstrating the new Russian craze called roof-flopping. Defying the Russian security forces, small groups of teenagers and young adults have taken to breaking into their city's tallest buildings risking arrest and possible imprisonment for following their danger-fuelled obsession. Under an assumed name, committed roof-flopper and photographer, Max Polazov, 22, has been breaking into the biggest buildings in his home city, Moscow since the tender age of 17.
