The classic romance between brain and heart—except it's a total biological lie! While the brain desperately professes "I can't live without you!" the heart smugly responds "I... can live without you!"
Fun fact: the heart can actually beat independently of brain signals thanks to its own electrical system (sinoatrial node FTW). In lab settings, hearts can keep beating outside the body while brains... well, they're just expensive Jell-O without oxygen. The heart's basically that independent partner who doesn't need your validation, while the brain is texting "u up?" at 2am.
