Blood Cell Circulation....in body

"An individual blood cell takes about 60 seconds to make a complete circuit of the body."

A blood cell (also called blood corpuscle) is any cell of any type normally found in blood. In mammals, these fall into three general categories: 

red blood cells — Erythrocytes 

white blood cells — Leukocytes 

platelets — Thrombocytes 

Together, these three kinds of blood cells sum up for a total 45% of blood tissue by volume (55% is plasma). This is called the hematocrit and can be determined by centrifuge or flow cytometry.

Lack of Sleep - Death

"A person will die from total lack of sleep sooner than from starvation. Death will occur about 10 days without sleep, while starvation takes a few weeks."

Cough - Spped

"A cough releases an explosive charge of air that moves at speeds up to 60 mph."

A cough, in medicine, is a sudden and often repetitively occurring defense reflex which helps to clear the large breathing passages from excess secretions, irritants, foreign particles and microbes. The cough reflex consists of three phases: an inhalation, a forced exhalation against a closed glottis, and a violent release of air from the lungs following opening of the glottis, usually accompanied by a distinctive sound. Coughing can happen voluntarily as well as involuntarily, though for the most part it is involuntarily.

A cough is a protective, primitive reflex in healthy individuals, and thus can occur while a person is unconscious. The cough reflex is initiated by stimulation of two different classes of afferent nerves, namely the myelinated rapidly adapting receptors, and nonmyelinated C-fibers with endings in the lungs.
