Sometimes, we really take the heart for granted. Especially on Valentine’s Day. The heart is so much more than a symbol of love – it’s also one of the hardest-working parts of our bodies, doing wonderful things for us without asking for much of anything in return.
Think about it, where would we be without our hearts??
On this February 14, don’t forget to send a special Valentine to your heart. After all, it does some pretty amazing things:
Feats of Strength
- Your heart is made up almost entirely of muscle. It is strong enough to lift approximately 3,000 pounds – roughly the weight of a compact car.
- Every day, your heart creates enough energy to drive a truck for 20 miles.
- Your heart beats with enough strength to shoot blood a distance of 30 feet.
- Because the heart has its own electrical impulse, it can continue to beat even when separated from the body, as long as it has an adequate supply of oxygen.
Feats of Consistency
- Your heart does the most physical work of any muscle during a lifetime.
- The heart begins beating at four weeks after conception and does not stop until death.
- Your heart beats over 100,000 times per day.
- Your heart will pump nearly 1.5 million barrels of blood during your lifetime – enough to fill 200 train tank cars.
- 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.
- Your heart doesn’t even skip a beat when you sneeze.
- 75 trillion cells in your body rely on the blood pumped by your heart. Only the corneas receive no blood supply.
Feats of Personality
- Your heartbeat changes and mimics the music you listen to.
- The blood vessels fed by your heart are more than 60,000 miles long. They could wrap around the world twice.
- Your heart has a sense of humor. A good belly laugh can send 20% more blood flowing through your entire body.
