For some folk, the thought of hurling yourself down a water-slide at significant speed fills them with dread.
For others, a holidays or hot day wouldn't be complete without one.
However, both camps will be unnerved by a recent video, which shows some poor hapless young man shoot off a slide – and onto the rocky terrain below.
Ouch. Yes, suffice to say that it makes for hide-behind-your-hands viewing.
The accident happened at a home just east of Austin in Texas and was – thankfully for the internet – captured on a phone and later posted to Facebook along with the hashtags #failvideo #brokenarm #notdead.
The footage shows David Salmon shoot down the slide, subsequently taking a turn too fast. His body rides up the side, and – airborne – he can next be seen tumbling 3metres over the edge.
“I'd gone down a few times and it was fast,” he has now said. “But this time, I just couldn't slow down, even threw my arm out, and went right over the edge.”
He added: “For a split second, I was like oh no. And then it was like a hard crash, and the rest was all just blurry.”
Mr Salmon furthermore told Fox 4 News that said he was conscious throughout most of the incident. Even though he remains in a lot of pain now, he also knows it could’ve been so much worse.
Still, in the aftermath he's been left with a broken left arm, and several fractured ribs; he has significant scrapes and bruises on his lower back, shoulders and side.
“It was excruciating,” David unsurprisingly said of the incident.
He and his friends had rented the Texas house for a long weekend and were taking turns on the slide last Sunday evening when the accident occurred.
“I could have easily broken my neck or my back,” David concluded. “And this could have been way worse.”
