Follow Your Heart

Ancient Egyptians believed the heart, rather than the brain, was the source of human wisdom, intelligence and soul. It’s not, of course, but it remains a marvel nonetheless – and obviously essential to the live pursuit of anything else.

The image above depicts the vascular architecture of the heart – an elaborate latticework of arteries and veins that sustains the organ even as the organ sustains the rest of your body.

As you ponder the picture, let’s get to the heart of the matter:

The human heart is roughly the size of a large fist and weighs between 10-12 ounces in men, 8-10 ounces in women.

An adult heart beats 60 to 80 times per minute; newborns’ beat faster: 70 to 190 beats per minute. A woman’s heart typically beats faster than a man’s. Over the course of a day, an adult heart beats roughly 100,000 times or 3 billion beats over an average lifetime.

The heart pumps roughly six quarts of blood throughout approximately 60,000 miles of branching vessels throughout the body. Blood travels at about 0.7 miles per hour. It takes 60 seconds for a drop of blood to circulate through the body. A kitchen faucet would need to run continuously, fully open, for at least 45 years to equal the amount of blood pumped by the heart over the course of the average person’s lifetime.

I thought you guys might be interested to know that I just officially accepted my offer from NASA today! I’ll be moving to the Johnson Space Center this summer in Houston Texas to help with the development of future flight decks and navigation systems. I can’t express how happy I am, It’s basically a dream come true!
