Look, we'd be the first to admit that when it comes to height, the only one type were interested in is heel.

In our headier more adventurous moments on holiday, we might have momentarily toyed with the idea of bungee-jumping or sky-diving, but then we had a word with ourselves before grabbing a drink and sitting those options out.

And this is why we're struggling to look at Angela Nikolau's Instagram account without biting down on closed fists and muffling a strangled wail.

From dangling off skyscrapers to taking selfies at dizzying heights, Angela's escapades have attracted almost a quarter of a million followers online.

And we're going to be honest here, we feel a bout of vertigo coming on.

Excuse us, while we lie down.
