Fight or Flight

A mechanism (?) that is part of the organisms self-preservation ingrown instinct. When it is in danger the organism will 'automatically start equipping itself for either a confrontation (fight) or looking for an exit to flee through (flight).

''imagine that you are a monkey and you're running along a
path past a rock and unexpectedly meet face to face another
animal. Now, before you know whether to attack it, to flee it,
or to ignore it, you must make a series of decisions. Is it
monkey or non-monkey? If non-monkey, is it pro-monkey or
anti-monkey? If monkey, is it male or female? If female, is she
interested? If male, is it adult or juvenile? If adult, is it of my
group or some other?... You have about one fifth of a second
to make all these decisions, or you could be attacked.''

Examples: Pay attention next time you are startled by someone watch how your body reacts.
