That's a horribly spurious statement. What statistics? What the hell kind of statistics can you have that would back up something like that? 1) It depends on how you do the prevention, and how you handle the event itself. 2) A lot of people would probably die without preventative measures, making it very cheap indeed. 3) What is the point of medicine if we afraid it's going to cost more? Medicine is about preventing.

But it's not more expensive. Most European countries spend much less on health care, but much more on prevention. It's very effective, and at the end of the day, it's really what medicine is about.
