The body is the hero

The total blood volume in our body circulates once every 13 seconds; 6o quarts of blood pass to the brain and the kidneys per hour, and return to the heart at the same rate. Those tremendous volumes give us the ability to run, to keep enough oxygen and sugar moving to our legs and arms so that our muscles can move even after hours of continuous effort. But the price we have to pay for all this quickness and power is a severe one. A bacterium from a cut in your finger can reach your brain in a little over four seconds. A pneumococcus in your lungs can reach the bones of your arms in three seconds.

Wise men, psychologists, philosophers and theologians suggest some ideas about the human, but the truth about the human may be found only through factual knowledge. The human is what evolution made them.
