What exactly makes a roller-coaster ride so much fun? Certainly the physics is part of it; the speed, the momentary weightlessness, the air, the normally impossible manoeuvres; but there is no doubt that the danger is as much, if not more a part of it. The idea of possibly dying makes roller-coasters a thrill just as it does for skydiving and bungee jumping.
What would happen if you rode a roller-coaster that you knew was completely safe? That is, you know for certain that there is a 100% chance of living through it because there was absolutely no possibility whatsoever of getting hurt (let alone dying). Would you still enjoy it? Would it feel the same?
I’ve also wondered the same thing about watching scary movies or eating hot peppers. Why do we enjoy things that are ostensibly harmful? That’s definitely masochistic.
