Winged shoes or meat mittens

Fight or flight is life's plight but I sit like stone
With a foe's arrival survival lies in whether cover's blown
Frozen in fright I won't fight just hope they won't see
In the garage of my camouflage sit and won't flee 

Adrenaline surges thoughts it purges, it's action or freeze
Speed explodes, violence unloads into nothingness squeeze
Viable for some, others it doesn't become as a defense
A shark in flight or a butterfly bite makes no sense

Some call me a coward disempowered but I think not
With one life to give I'd rather live, survival is what I got
In evolution living is absolution, no way is better than another
Sit, fight or flight, none is right, any as effective as the other
