Moving jobs, moving

house, changing partners, confronting the boss etc. may
cause us enough worry to fool the brain into thinking that the
intangible threat is in fact a sabre-toothed tiger, releasing
adrenaline that is not utilised behaviourally. Of course these
things are not life and death scenarios, but our senses think
that they are and still give us the instinct to run away, which
a greater majority do and so never achieve their life's
dreams. People often don't take chances in their life, career,
relationship or hobby because they feel this mammalian
instinct to run for their lives. Fear is what keeps people
ordinary. Humans, as a species, do not realise their potential,
because fear acts as a barrier between them and their
dreams. We are also left with the very corrosive effect of
Cortisol remaining in the blood stream when behavioural
fight or flight was not actuated.
