The man missed by the pool and fell upside down (a video from which you want to squint) You won’t believe it, but he survived. And we have photo proofs! October 4, 2018 Take your time to watch this terrible video from Sochi, which has already managed to go beyond the Runet. If you are very impressionable, then the description of the video below is enough for you. The tipsy man was going to make a long jump from the roof of a small building into the pool. Behind the scenes, Armenian speech is heard, friends are trying to dissuade him, but he is obscene to refuse them. At the most crucial moment, the edge of the roof treacherously falls off under a well-fed comrade, and he relishes his head smackingly directly on the tile (see 0:50). Many decided that after such a blow they do not survive or just remain with a Broken neck. But the man survived and even independently able to rise in a hospital bed! Of course, its fuselage was not sweet, but given the strength of the strike, we can say that he got off very easily. We hope that our hero will be fine and he will bring his brains in the skull box to the end of his life without splashing.
