For him, climbing is his passion and philosophy of life. Meet Alan Robert alias French Spiderman. The 52-year-old has done what no other has done before, by climbing the world's tallest twisted skyscraper in Dubai - that too without a safety harness.
Personifying the utmost human courage, the French climber scaled the 75-storey high Cayan Tower in the emirate's glitzy marina area, just relying on chalk and sticky tape on his fingertips to help him up.
The daredevil took just 70 minutes to climb the 1007-foot (307 meter) high structure.
The climb was captured on video at 8.25pm and spotlight followed his progress as spectators below look up and film the stunt on their camera phones.
The 'vertical tourist', in 2011, had climbed the world's tallest tower 2,717-foot (828 meter) tall Burj Khalifa using a rope and harness to comply with organizers' requirements.
He has also previously scaled the Eiffel Tower and around 50 of the world's tallest buildings in the world.
Robert, who likes to pushes the limits, was cheered by many spectators who continue to enthusiastically endorse him.
Robert, has suffered numerous falls during previous climbs, and has fallen seven times in his life. The worst was in 1982, when he fell from 15 metres, when his rope came undone while abseiling.
He went into a coma for five days. He had a fractured forearms, elbow, pelvis, nose, and nerve, leaving him partially paralyzed. He underwent six operations on his hands and elbow after the incident.
He announced his arrival in 1997 climbing the Petronas Twin Towers in Kuala Lumpur, Malaysia, but was arrested at the 60th floor, 28 floors below the top.
The madcap was a gifted rock climber, honing his skills as a young boy on the rocks around his home in the south of France.
Robert who just wanted to become a climber, got inspired after he saw a man climbing mountains in a film during his early years.
When asked about what excites to do such daring acts, he said, "to be at the top'.
