Scottish trials rider Danny MacAskill is either incredibly brave or spectacularly unhinged, depending on how you want to look at it.
His memorable brand of wince-inducing, BMX-meets-Parkour stunt riding has given him plenty of publicity in the past, but he's gone and outdone himself with his latest video. Shot in Gran Canaria, the footage shows him riding along dizzyingly high rooftops, somersaulting between buildings and generally doing stuff that would result in immediate death if it were attempted by any of us normal folk.
Just watching the video is more than enough of an adrenalin kick for us.
