As I have aged, my body ahs become less tolerant of wilder rides (but I still love trying them). My best Disney related story involved Mission Space. I was at Epcot the first week it opened to the public. That was, of course, long before they offered the more "gentle" option. I went to Epcot first thing the second morning of my trip, got one of the old school print out fast passes for MS and excitedly got on board. I was solo that trip and they placed me in a pod with three young girls. Half a minute into the ride, I feel myself getting very sick. The three girls on the ride were screaming with excitement and I recall thinking that I had to do everything possible to make sure I didn't puke on those three young girls.
The ride finally ended, I stumbled into the hallway, collapsed against the wall and sunk to the floor. A team of cast members rushed over to me and brought me water. Apparently, since the ride was so new, I was the first person (at least for that shift of employees) to get that sick on the ride, lol. So they were all very interested in exactly what I was feeling.
Over a decade later, I had convinced myself that the sickness was a one time off day experience and rode it again with my partner. Felt just as bad the second time! So now I only ride the gentle version
