Fight-or-flight Memes

Behold the terrifying gaze of an emu—nature's living reminder that dinosaurs aren't extinct, they're just plotting revenge! When your amygdala triggers that sweet, sweet fight-or-flight response, most creatures choose one path. But emus? They're evolutionary rebels with a cause! These flightless feathery menaces literally cannot flee by air, so they've supercharged their "fight" option instead. With powerful legs that can disembowel predators and speeds of up to 30 mph, they're basically feathered velociraptors with anger management issues. Just ask the Australian military who famously LOST A WAR to these creatures in 1932. That's right—the only species to win an official war against humans! Your puny adrenal glands are no match for millions of years of evolutionary rage-optimization!

Ever notice how your nervous system completely malfunctions when someone supremely confident enters the room? That's not just social anxiety—it's your parasympathetic system waving the white flag while your sympathetic system goes into full "fight or flight" mode, except both options somehow translate to "stand there looking like you've just witnessed an alien abduction." Thirty years of teaching neurophysiology and I still short-circuit when the department chair walks in unannounced. Evolution really dropped the ball on this one.
