Stress is a killer, so is standing still

I want to stop being myself day in and day out.
I want to run.
I want to duck, bob, weave, dive, roll, bound, and leap.
I want to shoot and dodge,
I want to kick in doors, and hunker down behind cover.
I want to fire fire fire,
run dry, and reload.
I want to rack up the kills, and feel the sting of becoming a simulated casualty.

I'm ready to shed these common clothes and don my armor.
I'm fed up wearing the merchant's disguise, I'm ready to shed it,
and put on the shining knight's armor that is my second skin.
