So go ahead—place a hand on your chest. Feel that quiet thumping? That’s not just a sound. It’s the soundtrack of being alive.
It’s not just a beat—it’s a two-part masterpiece of engineering. If you’ve ever listened to your heartbeat through a stethoscope—or heard one on a medical drama—you know the rhythm: lub-dub, lub-dub, lub-dub .
