That's intense! Imagine tipping over the point of no return and falling over 3x your hight, all while your feet and hips are strapped in place. No bailing from the stilts, no tuck and roll, just catching yourself like your landing the most insane jumping pushup, that is if your even falling face first.
The workers also don't look too young. I wonder if this is sort of like the case of there being no bold, old pilots. Just seasoned workers who learn never to push their luck when balancing all day, or just folks who really learned how to take a fall early in their life.
