Recipe for adrenaline rush: (1) Come home to learn that a naked man covered in blood was spotted wandering around your street but the police have not yet apprehended him; (2) Notice that the door to your garage apartment is ajar; (3) Retrieve firearm and creep into the apartment in stealth mode; (4) Sweep through the rooms like a slow motion ninja, stopping to listen for breathing and kneeling to look under beds; (5) Prepare to open the last of the closets with baited breath; (6) Turn door knob at the exact moment your cellphone rings; (7) Pretend your shout in response was a manly war cry intended to terrify and demoralize intruders.
