Secrets the roller coaster industry doesn't want you to know

Human beings are like the only animal on the planet that loves to be scared. We love horror movies, we love those dumb Halloween haunted houses with all the jump-scares, and we love roller coasters. Because internally, we know that horror movie villains can't kill us, that dude's chainsaw isn't real, and we're not going to get hurt on a roller coaster.

Now's the part where we tell you that all of your preconceived notions are incorrect. While it is true that the horror movie villain (probably) won't climb out of the screen and kill you, there have been one or two accounts of people with heart conditions dying during the most terrifying parts of horror films. And the same sort of thing has been known to occasionally happen in a Halloween haunted-house, too. But those incidents are pretty rare, compared to the accident statistics for roller coasters. So just how safe (or unsafe) are those wild rides that we'll happily spend hours standing in line for? They might not be telling us everything we need to know.
