Long before I had vertigo issues, I loved roller coasters. In fact, it could've been roller coasters that caused my middle-aged vertigo. And I SCREEEEEEEEEEAMED on them ... not because I was scared or compelled to or couldn't help myself ... but because it made the ride that much more fun. To just let it out and ride with the wind! And I would especially wind up for the most death-curdling scream I could whenever it zipped close by and standers-by watching the fun. The hope was it would freak them out so much they wouldn't want to try it. My attempts at shortening the line. In my even younger days, instead of the loud screaming at the standers-by, my friends and I would make loud vomit noises. Yes, I did such a thing. We did that on a lot of rides that came near any spectators. People really jumped and scattered.
