Replying to How do ppl take dubs off ~30ft cliffs and ski away like its nothing

I am an avid watcher of instagram clips and it always makes me curious how these people huck themselves off ~30ft cliffs and do double backflips and ride away. Like how do you get that mental fortitude that you are okay doing these things. Furthermore, they never seem to get hurt, I understand it’s powder but it still seems like it would hurt, and somehow their skis stay on. Like do you just crank the dins up to the max or what. Also how do you even take those impacts, it would seem like such heavy impacts on your legs.
