I disagree with that. If you have the balls to go up there in the first place I dont think it matters whether you have a parachute attached or not, its the bodies natural reaction to being in a dangerous environment.
Just like Go Ape above, people still brick it even though they are attached by a rope.
Doing stuff like that the thrill is knowing that you could easily die, and whether you have a parachute or not that thrill is still there or people wouldnt do it with a parachute.
I would consider doing stuff like that, but I have responsibilities these days that stop me doing stupid stuff 🙁
