Does Fear Define YOUR Comfort Zone?

In studies of the brain’s neurology, fMRIs show that when faced with uncertainty our brains decrease the blood flow to the reward center while increasing blood flow to our emotional circuitry — the limbic brain, priming us for fight-or-flight response.  Conversely, in studies of those with lesions in their orbito prefrontal cortex who couldn’t feel fear, the presence of uncertainty caused no fight-or-flight reaction.  What would your life be like if you could meet the unknown with no perceived risk or threat?  What more would you experience if you were effortlessly stepping out of your comfort zones?
