• Your heart beats 100 thousand times a day or 35 million times a year. That's more than 3 billion times in the average lifetime.
• You have a total of about 5 liters of blood circulating through your body 3 times every minute. In one day, the blood travels nearly 20 thousand kilometers or half way around the earth.
• Your system of blood vessels (arteries, veins and capillaries) is almost 100 thousand kilometers long- well over twice around the earth.
• The adult heart pumps over 3 litres of blood each minute throughout the body - adding up to approximately 2 thousand gallons of blood each day.
  Over the course of a lifetime, it may pump a million barrels of blood - enough to fill 3 super-tankers.
• All this is done by an organ the size of a fist in a child or the size of two fists in an adult that normally never stops.
• With a little TLC such as moderate exercise, good diet and avoiding drug abuse, you can keep this wee miracle going for an extra decade or more of healthy life.
