Did you like climbing trees when you were a kid?
An English man obviously really liked to climb as he was recently seen climbing London's Shard skyscraper without harness.
Anyone can take the lift to the top of the Shard tower to get great views over London, but this man decided that wasn't enough of a thrill.
Check out this eyewitness video showing him climbing up the outside of the 1,017-foot glass tower -- the European Union's tallest building -- on Monday, and local police say he did it without a harness.
"Emergency services attended and the man went inside the building where he was spoken to by officers," the police department tweeted. "He was not arrested."
