If you climb enough, you are going to fall. It’s just part of the sport.
However, climbers spend a disproportional amount of time worrying about falling then actually falling.
That’s because falling in the air is done in a matter of seconds. But the time we imagining the worst, only makes the experience that much more terrifying.
In my experience, climbers are not afraid of flying in the air, it is the uncertainty of all of it.
If we knew what would happen next then it wouldn’t be an endeavor worth pursuing.
