Basal fear work via adrenergics mechanism, to raisen heartbeat,bloodpressure,senses,etc.
the fight or fly response common to "higher bios"

How Psicological fear, like the fear of the unknow, work?
And why some people are less affected by this?(Some are even affascinated . Some simply want to find the true,pure&simple).How exactly the chemistry of this is working?
