Many people take the beating of their hearts for granted, but when one considers all of the work that the heart performs, it is astounding. If you have a healthy heart rate of 60 beats per minute and you live to be 80 years old, your heart will beat (contract and relax) 2,522,880,000 times. Your heart pumps approximately 2,000 gallons of blood each day. In 80 years of life, it will have pumped a total of 58,400,000 gallons of blood.
