So basically a bunch of older people who got dizzy and fell or had seizures after riding rides they probably would have figured out they shouldn't have been on in the first place if they read the warning sign before getting on the ride.
Don't get me wrong, I still want to be going to the parks when I'm retired but hopefully I'll be smart enough to know my limitations, after I turned 35 I figured out it wasn't a good idea to ride Everest back to back.
