However today, we will focus on the human heart and look at some interesting facts that it bears:

1. Every day the heart creates enough energy to drive a truck 20 miles or 32 kilometres. In a lifetime, that is the equivalent of driving to the moon and back.

2. When the body rests, it only takes 6 seconds for blood to travel from heart to the lungs and back. Only 8 seconds for it to go to the brain and back and only 16 seconds for it to reach the toes and travel all the way back to the heart.

3. A kitchen faucet would need to be turned on all the way for at least 45 years to equal the amount of blood pumped by the heart in an average lifetime.

4. The heart begins beating 4 weeks after conception.

5. The human heart is not ‘heart-shaped’, a cow’s heart is closer to the ‘heart-shape’ usually used to indicate the heart

6. The largest artery in the body, the aorta, is almost the diameter of a garden hose. Capillaries, on the other hand, are so small that it takes ten of them to equal the thickness of a strand of human hair.

7. The first heart pacemakers were plugged into a wall socket.

8. Happiness and a strong sense of emotional vitality helps lower your risk of heart disease.

9. Your heart is about the size of your two hands clasped together.

10. Your heartbeat changes and mimics the music you listen to.

11. Your left lung is smaller than your right lung to make room for your heart.

12. Eating dark chocolate every day reduces the risk of heart disease by one third.
