Our hearts pump at a rate of 70-75 beats per minute. Though weighing only 11 ounces on average, a healthy heart pumps 2,000 gallons of blood through 60,000 miles of blood vessels each day. Every day, the heart creates enough energy to drive a truck 20 miles. In a lifetime, that is equivalent to driving to the moon and back. A healthy heart can do amazing things. Conversely, if our heart malfunctions, our whole body shuts down.
