@mc.alligator6: The strongest muscle in your body never sleeps — it pumps 5 liters of blood every minute, 24/7, for your whole life. Just 150 minutes of cardio a week cuts your stroke risk by 50% and dementia by 30%. Treat it right, and it’ll literally add years to your life. ❤️🔥 #musclefacts #sciencerap #learontiktok #fitnessmotivation #hearthealth
