I read an article about fear, and how it effects our brain. Result of study take place in airplane. The airplane has some fuel consumsion. Then the captin  turned off all electrical machine to avoid the situation get worse. He called nearest station to help with landing. This accident took place just before 9\11. Some passengers of this flight being  monitored by sychologist.  The most important point is that changing some idea in mind wouldn't be possible in near future.
