As we celebrate Valentine’s Day, a day of hearts and flowers, chocolate and love, here are some fun facts about your sweet heart.
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.

The heart of an average man beats approximately 70 times a minute. The average woman has a heart rate of 78 beats per minute.
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.
