Does fear keep chaos in check?

Should I find myself in nature and
carried to paralysis by the growl
of, let’s say, a tiger, fear would
be a reasonable, useful, response.

The amygdala puts down it’s drink
and starts issuing edicts, kicks some
hormones and the nervous system
awake. Showtime, fight or flight.

Which does not explain the presence of
fear on so many lesser, no tiger, occasions.
The time has come to clip its wings. I think
this fear has claimed too much dominion.

It’s doubt, masquerading as fear, that cripples
all the many moments not fight or flight.
The inability to decide, and act, miscast
as fear. It’s rarely a tiger at your door.
