Your heart is basically a living museum of evolutionary relics. Deep in the womb, your ticker started as a simple tube, just like a worm's. Then it twisted, folded, and grew chambers like a deranged origami master. The result is a four-chambered, turbo-charged pump that would make a plumber weep with envy. And get this: it starts beating at just 21 days old—before you even have a brain to appreciate how ridiculous that is.
By the time you're born, it's already clocked in for nine months of overtime. Take a moment of silence for all the unpaid labor your heart did before you had a single conscious thought. It's the ultimate freeloader that never clocks out.
