Flaviu Cernescu, a 31-year-old Romanian, calls himself an extreme sportsperson. However, he is, by his own admission, scared of heights. It isn't just psychological — he actually suffers from vertigo.
What, then, possessed him to ride a unicycle across the edge of a dam in Romania that is 166 m high?
No wonder this insane dude appeared on a British reality TV show called 'World's Most Talented'.
Do not watch this video if you have a fear of heights.
