Can you live without a heart?

How does the heart never get tired?
Cardiac muscle resists fatigue so well because it’s got more mitochondria than skeletal muscle. With so many power plants at its disposal, the heart doesn’t need to stop and chill out. It also has a steady supply of blood bringing it oxygen and nutrients.
How long can a human heart last?
As we’ve seen, humans have on average a heart rate of around 60 to 70 beats per minute, give or take. We live roughly 70 or so years, giving us just over 2 billion beats all up. Chickens have a faster heart rate of about 275 beats per minute, and live only 15 years. On balance, they also have about 2 billion beats.
Does your heart stop when you sneeze?
When you sneeze, the intrathoracic pressure in your body momentarily increases. This will decrease the blood flow back to the heart. The heart compensates for this by changing its regular heart beat momentarily to adjust. However, the electrical activity of the heart does not stop during the sneeze.
