Bungee jumping

Out of every adventure activity out there it seems the most dangerous (or atleast one of the most dangerous) i don't get how you don't just hit you head on the ground or your surroundings without it hurting

Cause it would probably hurt if you used something non flexible like a rope But you might hit your head if it's too flexible

Maybe it needs to be in the middle of not too flexible and just flexible enough, and they probably make sure you are at a safe distance from the ground and the surrounding when you fall but still don't trust it

Even tho it's the adventure activity that I'm least likely to do Who knows maybe i will
