Uncover 4 surprising heart facts from a cardiovascular surgeon

• Dr. Jeremy London, a cardiovascular surgeon, shares four lesser-known facts about the heart.
• The heart, though small (fist-sized), is incredibly powerful, beating 100,000 times daily and pumping 2,000 gallons of blood.
• The body's blood vessels, if stretched out, would extend nearly 60,000 miles.
• Broken heart syndrome is a real diagnosis, mimicking a heart attack but without blockages, often triggered by intense emotional stress.
• While resilient, the heart is not invincible; physical and emotional care are crucial for its health.
