The Heart of the Matter

I don't know about the accuracy of the following "facts" about the heart, but, if true, they are quite amazing:

1. "The entire blood system is estimated at 62,100 miles.
2. There are 12 pints of blood in an adult male and 9 in an adult female.
3. 5 - 10% of the body's total energy is used to keep the heart beating.
4. 5 - 7.5 gallons of blood are pumped per minute during strenuous exercise.
5. A heart contracts 2.5 billion times during the average lifetime.
6. The heart pumps 3.1 billion gallons of blood over a lifespan of 75 years.
7. 46 of the world's largest oil tankers could be filled with blood pumped by the human heart in a normal lifetime.
8. There are about a billion red blood cells in 2 - 3 drops of blood.
9. 300 million cells die each minute. Two percent of blood cells die each day and are replaced."

Think about it! Like this fellow once did:

"What a piece of work is man! How like an angel, how like a god.
The beauty of the world."
- William Shakespeare

I find the following book quite useful: Strength Training Anatomy. By Frederic Delavier. Champaign, Illinois, Human Kinetics, 2001. 124 pages. ISBN: 0736041850. Revised edition of "Guide des mouvements de musculation" Paris, Ditions Bigot, 1998. An outstanding illustrated guide to muscles at work. Both male and female models are used.
