I was on a guided hike to the summit of the Drakensberg. At the very top, a pristine rock pool sat perched right at the lip of a massive waterfall, its water spilling over the edge into the abyss below. It was a scene of rugged beauty—and the perfect stage for some high-altitude bravado.
There was a girl in the group I was particularly keen to impress. I figured a fearless, mid-air leap into that infinity pool would cement my status as the alpha-adventurer of the expedition. I took a breath, channeled my inner action hero, and launched myself off the ledge.
The moment I hit the surface, the laws of thermodynamics struck back. The water wasn't just cold; it was a liquid ice-pick that instantly vacuum-sealed my lungs. Every ounce of "cool" evaporated in a millisecond.
As the current began nudging me toward the edge of the falls, I produced a noise usually reserved for a cat being dunked in an ice bath. I scrambled for the rocks, limbs flailing like a panicked crab, desperate to escape the liquid nitrogen before I became a permanent part of the scenery at the bottom of the mountain.
I went in hoping to look like a mountain god; I left looking like a man who had just been electrocuted by a puddle at three thousand metres.
