Tidbits from the tome
About adoption
Moreover, since most birth mothers are themselves unmarried, they reject the idea of another single woman receiving their baby. Only two countries readily allow assignment of infants to middle-aged single women: Vietnam and Guatemala.
About breathing
Normally, the air we breathe is 20 percent oxygn and the remainder largely nitrogen with a small amount of carbon dioxide. Our lungs are built like a honeycomb, and the sacs in this honeycomb are called alveoli. The oxygen we inhale passes through the thin wall of these alveoli into the bloodstream. When bacteria and mucus fill the lungs, as in pneumonia, it is difficult for oxygen to pass through the clogged sacs and into the blood.
About eating
The most common form of malnutrition and immune deficiency in poor countries is due to the lack of adequate protein, as in severe starvation.
About nutrition
Furthermore, aside from relatively common dietary deficiencies -- lack of vitamin B12 causing pernicious anemia, or insufficient vitamin C giving rise to scurvy -- little is known about the effects of nutrition on many bodily functions.
