1Although the content and character of economics cannot be described briefly, numerous writers have attempted that.
2 <span>An especially useless, though once popular, example is: «Economics is what economists do.»
3</span> notable economist of the last century Alfred Marshall called economics «a study of mankind in the ordinary business of life.»
4<span>We may make better progress by comparing economics
with other subjects. Like every other discipline that attempts to
explain observed facts (e.g., physics, astronomy, meteorology),
economics comprises a vast collection of descriptive material organized
around a central core of theoretical principles. The manner in which
theoretical principles are formulated and used in
applications
varies greatly from one science to another. Like psychology, economics
draws much of its theoretical core from intuition, casual observation,
and «common knowledge about human nature.» Like astronomy, economics is
largely nonexperimental. Like meteorology, economics is relatively
inexact, as is weather forecasting. Like particle physics and molecular
biology, economics deals with an array of closely interrelated phenomena
(as do sociology and social psychology). Like such disciplines as art,
fantasy writing, mathematics, metaphysics, cosmology, and the like,
economics attracts different people for different reasons: «One person’s
meat is another person’s poison.» Though all disciplines differ, all
are remarkably similar in one respect: all are meant to convey an
interesting, persuasive, and intellectually satisfying story about
selected aspects of experience. As Einstein once put it: «Science is the
attempt to make the chaotic diversity of our sense-experience
correspond to a logically uniform system of thought.»

Water is a physical need of the human body. We can live without food up to 30-40 days, but without clean drinking water we won’t survive even 3-4 days. This should come as no surprise: the body of an adult consists of around 60-70 percent of water. It is contained in all tissues, and it is essential for metabolic processes, temperature regulation, nutrients transportation via the circulatory system and waste removal. It participates in almost all physiological processes. Lack of water can cause various diseases – from headache to muscle spasms and cramps.
