What a dependable little organ is the human heart! Everyday, including Sundays and Holidays, this little engine keeps on pumping nonstop. And it continues even while we sleep.
The heart never complains about the weather which is very hot now and never asks for a vacation. It works best when treated well, but continues to serve even when working conditions are stressful.
How much we need the heart! If one eye is blind, we can still see with the other. If one ear is deaf, we can still hear with the other. if we lose one leg, we can still work with a crutch. But we only have one heart.
WHILE WE LIVE
Our “pumping machine” is about the size of one’s fist and weighs just a little more than half a pound. It beats about 70 times a minute, 4200 times an hour, 100,800 times a day, and 36,792,000 times a year. The heart of a 70 years old person has beaten over 2.5 billion times.
The heart generates enough energy in 50 years to lift a battleship out of the water. In the average lifetime, it pumps enough blood to fill 3.3 super-tankers !
