Hey, look up there. Did you take your vertigo medication this morning? Fully recovered from last night's shameful tequila-flavored swamp dive? You could do with watching a relaxing, serene video clip of tightropers crossing over a 100-meter waterfall. It'll put you at ease. Just watch.

No, suckers!!! Gotcha. This video is a frightening test of the will for the viewer, only made easier due to the security of the tightropers' harnesses. Two high-wire artists took on the open, unruly chasm of Victoria Falls between Zimbabwe and Zambia, committing to a 100-meter walk over scary waters.

Take a deep breath: Lukas Irmler & Reinhard Kleindl made it to the other side safely, but hold this quote, from Kleindl, close to your heart: "Optically it's very difficult because the spray comes from the sides and it's like waves, they try to drag you, so it's really difficult for the optics and obviously everything is very heavy because it's soaked with water."

A metaphor for life.
