What is the difference between phobia and normal fear?
Fear is the emotion that protects us from doing things that might endanger us. Most people, when faced with a tiger, would run away in order to avoid being eaten. Likewise, fear stops us from stepping to close to a ledge on a high building. Some people are more fearless than others but essentially we all have the same type of reaction to danger. The more risky a situation is, the more intensely afraid we feel, but once the threat has passed we recover within a few minutes.
