Behold! The great cardiac deception we've all fallen for! The iconic red heart symbol we doodle everywhere bears about as much resemblance to our actual heart as a stick figure does to human anatomy. While we're busy drawing those cute symmetrical shapes, our real hearts are over here looking like muscular, asymmetrical pumping machines with tubes sticking out everywhere! Nature clearly didn't get the Valentine's Day memo. The real heart is basically saying, "You thought I was going to be all cute and symmetrical? SURPRISE! I'm a complex biological pump that keeps you alive, not your dating profile logo!"
