I don't know why folk put themselves through stuff like that. I don't think their minds work properly, they are supposed to have a self survival instinct that says not to go through anything like that or the primal "scare" mechanism/algorithm kicks in.
Roller Coasters are only for going on because you have such a mental sister who says she likes them and one can't let those of a female persuasion to think they have one up on you. So you sit there teeth gritted, with a big grin, telling yourself, "It'll be over in a minute and you'll be ok, It'll be over in a minute and you'll be ok, It'll be over in a minute and you'll be ok, .....". And wondering why there's all that screaming. Can't they keep quiet ? If they don't like it and it makes them want to scream why do they get on it ?
The world is mad, totally mad.
