Health
Health is the ability of a biological system to acquire, convert, allocate, distribute, and utilize energy with maximum efficiency. The World Health Organization (WHO) defined human health in a broader sense in its 1948 constitution as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity." This definition has been subject to controversy, in particular as lacking operational value, the ambiguity in developing cohesive health strategies and because of the problem created by use of the word "complete", which makes it practically impossible to achieve. Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction.
Population
In biology, a population is all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding. The area that is used to define a sexual population is defined as the area where inter-breeding is potentially possible between any pair within the area, and where the probability of interbreeding is greater than the probability of cross-breeding with individuals from other areas.
Population
If this were true, the population of the world would be at a stand-still. In truth, the rate of birth is slightly in excess of death. I would suggest that the next edition of your poem should read: “Every moment dies a man, every moment 1 1/16 is born.” Strictly speaking, the actual figure is so long I cannot get it into a line, but I believe the figure 1 1/16 will be sufficiently accurate for poetry.
Charles Babbage, cited in: New Scientist, 4 December 1958, pg.1428.
Health
There are three wicks you know to the lamp of a man's life: brain, blood, and breath. Press the brain a little, its light goes out, followed by both the others. Stop the heart a minute, and out go all three of the wicks. Choke the air out of the lungs, and presently the fluid ceases to supply the other centres of flame, and all is soon stagnation, cold, and darkness.
Oliver Wendell Holmes, Sr., The Professor at the Breakfast Table (1859), XI.

Of all the garden herbes none is of greater vertue than sage.

A study linking changes in plant and microbial ecosystems to environmental factors has highlighted how these ecosystems may alter in response to climate change.
