The February 2007 issue of National Geographic has an interesting piece on the human heart, and it’s called “Mending Broken Hearts”. It concerns the hearts’ function, maladies and how today’s medical advancements are able to extend life.

“The human heart beats 100,000 times a day, propelling six quarts of blood through 60,000 miles of vessels”. It is 20 times the distance across the U.S. from coast to coast.

“The blood flows briskly, surging out of a ten-ounce heart so forcefully that large arteries, when severed, can send a jet of blood several feet into the air.”

In ancient times, very little was known about the heart, whose rhythmic beating coincided with all the functions of life and whose cessation meant death. The references in the Bible to the heart are used figuratively to describe what it means to be human. We see this in the psalmist’s confession, “My flesh and my heart may fail, but God is the strength of my heart and my portion forever” (Psalm 73:26).
