I think it is more a personal affinity or dislike for thrill rides than it is a matter of age. I'm 63 and dislike the same knock me around rides as I did when I was in my 20's. I can't (and won't) ride Space Mtn (did so twice and it's one of those unforgettable in a bad way memories), Tower of Terror (experienced it 1 time and will NEVER do so again) - and so as much as I would love to experience rides like Rise, Tron, etc - I will not put myself through that. Every few years I'll ride Thunder Mtn, Tiana, 7 dwarfs etc - because I'm able to position myself in such a way that I can support my body from whipping movement. I see "old" people ride all these rides without any issues. For me, it has been and will be an issue. It would be hard for me to judge what others would like or dislike - dizziness isn't as much of an issue as sudden movements are. Being vertically challenged (about 5 ft tall) it's hard to use my legs to position myself without eventually sliding down on a seat.
What I'm basically saying is if these rides didn't bother you before, they may not bother you now. Or... they may. I'd rather be safe than sorry - my brother - who is in his late 50's decided to ride Rise because he loves rides like that. He reported being sick for almost 48 hours with vertigo he'd never had. He thought it was the visual part more than anything but either way it's not something I'd want to try.
