Everyone in life will suffer from anxiety at some point, whether that be worrying how much car repairs maybe, to concern that the red wine stain won't come out of the carpet, but I think that's the difference between anxiety and fear. Fear is the key to the adrenaline release.
You're right, from what I understand the bodily reactions to adrenaline are the same in anyone, which would mean the majority of people will indeed suffer a form of 'panic attack' at some point in their lives.
Because our fears revolve around day to day living, the inctinct to flee probably kicks in more often whereas in most cases it would only come into play say by finding a big spider in the bathtub. Everyone in life has a phobia of something so depending on the level of fear that must control the strength of reaction.
I know most people would consider an adrenaline rush as a good thing though, and purposely try cause the reaction. In one of my posts I wrote how I enjoy the adrenaline rush I have after achieving getting into say a shop, but then I hate the feeling of a panic attack. Isn't this a contradiction?
Maybe the euphoria is created as an after effect. Once the adrenaline levels return to normal the brain will release endorphins to help to calm the body down?
This hasn't occured to me before but sort of makes sense in explaining the natural high thrill seekers get and why I feel that way post panic.
If anyone happens to know if this is what happens I'd be interested to know
