Me, I had & have zero interest in going on any roller coaster. When I was 19, I decided I needed all my luck for some of my other dangerous pursuits & didn't want to waste it on surviving a ride. I've never been on a roller coaster but I also have little desire for manufactured endorphins. And the older I get, the less I want to be in any sort of stressful situation, even a controlled one. I'm sure there's a basic difference between people who like rides & those who don't. I wonder if it's the same as the difference between people who want weddings & people who want to be married. A ride seems like a wedding ~ a big deal that's over in a flash, while a marriage holds constant, unpredictable thrills.
