Just got a thread inspiration reading that new Fear of Heights thread.
The folks that produced/created Fear Factor understand something about human nature and the fact that the show is STILL on the air proves it. We are irrational creatures and have many different phobias but we also have another flaw - we're greedy; which is the more powerful flaw? This is the underlying premise of the show 'Fear Factor'.
Presupposing you had a fear of heights what would be your bottom dollar to dangle from a wire over the Grand Canyon for 2 minutes?
Why stop there - what would be your bottom dollar for performing other tasks which violate you psyche's normal level of acceptable behavior? Say, eating a live earthworm or getting into the boxing ring with Mike Tyson (in his heyday)?
