n times of fear or danger, there is a molecule that helps every
human being: adrenaline. For example, this hormone puts the
brain of a pilot whose plane has engine trouble into a state of alarm. It
sends more blood and sugar to his brain cells, enabling the pilot to exercise
greater care and attention. At the same time, it raises his pulse and blood
pressure, enabling him to be more alert and react more quickly. It gives the
muscles extra strength, raises the level of sugar in the bloodstream and thus
enables the pilot to generate the extra energy he needs.
This miraculous hormone produced—and stored—by the adrenal
glands possesses many properties and is a proof of God's sublime knowl-
edge and immaculate creation.
How does adrenaline give rise to these effects? When danger arises,
the equivalent of an alarm button is pressed in the body. The brain issues a
lightning-fast command to the adrenal glands. Cells inside the gland enter
a state of activation and secrete adrenaline molecules. Entering the blood-
stream, these molecules are distributed to various regions of the body.
