Living life on the edge is being taken to new heights, literally, by "rooftoppers" who are getting themselves photographed hanging off buildings by just their fingers at nausea-inducing heights.
The death-defying rooftopping, or skywalking, trend has been documented as being popular in Russia and Ukraine in the last few years.
Daredevils are depicted on top of buildings, cranes, and constructions sites without safety harnesses or nets, dangling at alarming heights - often by just one hand.
Ukranian "Mustang Wanted" is a former legal advisor who gave up his desk job to pursue a career as a skywalker.
The latest video of his outrageous climbing adventures show him doing chin-ups a few hundred metres above the ground in Kiev, alongside a compilation of other jaw-dropping feats.
He also warns against viewers trying the craze themselves.
'[T]he following videos and photos feature stunts performed by professionals. I really insist that no one attempt to recreate or re-enact any stunt or activity performed on this site. Even if you're totally sure that you can do that, you are putting yourself in danger. So, please, don't try to recreate my stunts. I mean it!'
