I wonder how much this study cost

At least the Germans paid for it.

It still kinda falls into the "F*cking OBVIOUS" catagory, though.

Dr Jurgen Kuschyk, from the University Hospital in Mannheim, which is affiliated to the University of Heidelberg, said: "Individuals who have suffered a heart attack, have heart disease or irregular heart rhythms should not ride a roller-coaster.

"The rising heart rate in riders with pre-existing heart disease could result in heart attack, irregular heart rhythms and possibly sudden cardiac death."

Yeah, if you have a heart condition, stay off the scary rides.
Duh!

They didn't say anything about scary wimmin, though. I guess they'll study them next.
