What’s something you tried once and immediately knew it wasn’t for you?

@sstronaut] I've never wanted to try most fairground rides! The Gallopers, yes (rotary rides all revolve as that Caterpillar does, clockwise, right to left, in British fair tradition); the Dodgems yes (I was quite good at making two cars trying to hit mine from each side, hit each other instead!). The high-speed and high-altitude rides though.... No!
