Abstract:
"Saving a life" is a credible definition of heroism in the United States. However, the pervasive societal impression of immediate gratification has led to a widespread recognition of "life saving" only in circumstances of immediate danger. The lengthening national life expectancy is not accorded respect as an accomplishment in and of itself. Families of dying, elderly persons still mistake the "loss" by failing to appreciate the many times this life has been saved and esteeming the accomplishment that death at a later age poses. Public health and preventive medicine both suffer general disregard for this shortsighted perspective, from the public and those who determine federal funding priorities. This narrative expounds on this frustration and describes its implication for the future of public health as it is currently practiced in this nation.

Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

Metabolism
The basic function of an organism is to consume energy and molecules in foods, convert some of it into fuel for movement, sustain body functions, and build and maintain body structures. There are two types of reactions that accomplish this: anabolism and catabolism.
Anabolism is the process whereby...
