Yes. I've experienced the superhuman power of the fight or flight respinse. It's unreal.
Adrenaline is a crazy drug. Some damn Walmart delivery came at 10:30 at night and we were already in bed and she rang the damn doorbell. Immediately grabbed my pistol, adrenaline pumping just to pick up a package from the porch... Adrenaline makes me feel like I can take on the world. It's wild.
