The other day, one of my daughters and her friend were showing me all the neat features of their new phones. Cutting edge technology and massive memory that fits in your pocket…a screen that you don’t have to touch – just wave your hand or hover your finger over the screen and it will do what you want it to do…everything but make coffee and fry bacon. The latest and greatest in smart mobile devices. I love that stuff to, but I have to admit that my smart phone is several years old and I think I’m finally at the place where I’ve caught up with it’s smartness…but, alas, it is seriously outdated. (Hmmm…wonder what that says about me. 🙂 )
There is another mobile device that predates all the smart phone and other electronic gadgetry every imagined.
- The average adult heart beats 72 times a minute; 100,000 times a day; 3,600,000 times a year; and 2.5 billion times during a lifetime.
- 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.
- A kitchen faucet would need to be turned on all the way for at least 45 years to equal the amount of blood pumped by the heart in an average lifetime.
- The volume of blood pumped by the heart can vary over a wide range, from five to 30 liters 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.
- Because the heart has its own electrical impulse, it can continue to beat even when separated from the body, as long as it has an adequate supply of oxygen.
- The fetal heart rate is approximately twice as fast as an adult’s, at about 150 beats per minute. By the time a fetus is 12 weeks old, its heart pumps an amazing 60 pints of blood a day.
- The heart pumps blood to almost all of the body’s 75 trillion cells. Only the corneas receive no blood supply.
- During an average lifetime, the heart will pump nearly 1.5 million barrels of blood—enough to fill 200 train tank cars.
- Five percent of blood supplies the heart, 15-20% goes to the brain and central nervous system, and 22% goes to the kidneys.
- The “thump-thump” of a heartbeat is the sound made by the four valves of the heart closing.
- The heart does the most physical work of any muscle during a lifetime. The power output of the heart ranges from 1-5 watts. While the quadriceps can produce 100 watts for a few minutes, an output of one watt for 80 years is equal to 2.5 gigajoules.
- The heart begins beating at four weeks after conception and does not stop until death.
And, there are many more facts about the human heart.
But, in my mind, the most important facts about my heart is – –
I can choose to keep it safe and secure with me, or risk its care with someone else.
It can be totally crushed and broken, yet be healed beyond anyone’s understanding.
It can survive immense loneliness in the midst of a crowded life.
It can connect with another’s in ways that transcend words or actions.
It can thrive in hope in the midst of unmitigated disaster.
It can flourish in heavenly delights and hellish depressions.
It can see the impossible when the eyes fail.
In any kind of comparison, technology doesn’t stand a chance.
