As a tourist, if you're within a 15-mile radius of a very tall building then chances are, you feel obliged to visit.
Even though you can predict that, like every other tall building you've visited, it's just a lot of money and time for a good view.
Over in Canada, they've come up with a much better idea. Why bore people to death when you can actually terrify them with the actual possibility of it instead? The EdgeWalk gives daring visitors the chance to lean off the side of Toronto's CN Tower and face the 1,168ft fall below.
Reassuringly, they are attached to safety harnesses and breathalysed first. The experience costs $175 (£108) and the attraction will open on September 15th.
Yeah, we might just sit this one out...
