If you have a fear of heights, you might want to think twice about reading any further.

Urban climber Vitaliy Raskalov and his partner Vadim Makhorov are a Ukranian-Russian duo that travels the globe to scale the world’s tallest buildings and monuments, all without the use of safety harnesses. They take photographs and videos of their escapades and posts them online for the world to see, and they are all vertigo-inducing to say the least.

They have conquered the Sagrada Familia, Cologne Cathedral, Eiffel Tower, some of Dubai’s newest skyscrapers, and Giza’s pyramids, among others in the last few years. Their latest feat was when they flew to Brazil to climb Christ the Redeemer.

Eluding travel bans and security, they use pseudonyms to avoid detection and often disguise themselves as local workers to get to the tops of buildings.

Of course, their adventures aren’t without consequences. They have been caught several times for trespassing, and have even received an official country-wide ban from the Chinese government after they scaled the Shanghai Tower.

Raskalov revealed to the Daily Mail that the higher he climbs, the less fear he feels. He also claims to have never been close to falling, or feared for his life during a climb.

“I’d rather die falling from a great height than fall from a building four stories high and end up crippled,” Raskalov said.

He has also left his Instagram fans with some words of wisdom, ones that make us all contemplate our current lives:

“Throw away your brilliant career and start living!”
