ABCNews.com is throwing there poker in the fire on if coasters are safe or not. This article takes more of a negative angle than most IMO.
Several studies have documented neurological injuries, mainly sudbural hematomas or brain bleeding, occurring in riders of coasters. None of the studies has concluded that the rides cause subdural hematomas, but some neurologists warn that the incredible G- forces [force of gravity, which changes with inertia and momentum on a roller coaster and in space] and speeds of the new coasters may cause this brain bleeding to occur.
