When I reached what looked like the centre of the bridge, I tentatively placed both my hands on the cold metal bar, leaning into it, to peer meekly over the edge. I’d been told by my tour guide, in his jovial Slovenian-English, that the drop was ‘only’ 10 metres. I was sceptical, it looked much higher. Much higher than a few minutes before when I’d eagerly raised my hand as volunteer to be the first to jump. Glancing back to the crowd standing on the embankment, I could see they were shouting something through the makeshift megaphones they had created with their hands. They could be words of encouragement or impatience I couldn’t tell, any sounds they were making had been stolen by the winds.
