Fun Fact of the Day – In the average lifetime your heart beats over 2 and a half billion times at a pace of 100,000 beats per day. In that single day blood travels around 19,000 km (just under 12,000 miles) which is almost 5 times the distance across the US from Los Angeles to New York. That means that in the average lifetime your blood will travel the distance to the moon and back over 630 times.
