Geratology
Gerontology ( ) is the study of the social, cultural, psychological, cognitive, and biological aspects of aging. The word was coined by Ilya Ilyich Mechnikov in 1903, from the Greek , ''geron'', "old man" and , ''-logia'', "study of". The field is distinguished from geriatrics, which is the branch of medicine that specializes in the treatment of existing disease in older adults. Gerontologists include researchers and practitioners in the fields of biology, nursing, medicine, criminology, dentistry, social work, physical and occupational therapy, psychology, psychiatry, sociology, economics, political science, architecture, geography, pharmacy, public health, housing, and anthropology. The multidisciplinary nature of gerontology means that there are a number of sub-fields which overlap with gerontology. There are policy issues, for example, involved in government planning and the operation of nursing homes, investigating the effects of an aging population on society, and the ...

Diet (nutrition)
In nutrition, diet is the sum of food consumed by a person or other organism. The word diet often implies the use of specific intake of nutrition for health or weight-management reasons (with the two often being related). Although humans are omnivores, each culture and each person holds some food preferences or some food taboos. This may be due to personal tastes or ethical reasons. Individual dietary choices may be more or less healthy. Complete nutrition requires ingestion and absorption of vitamins, minerals, essential amino acids from protein and essential fatty acids from fat-containing food, also food energy in the form of carbohydrate, protein, and fat. Dietary habits and choices play a significant role in the quality of life, health and longevity. Health A healthy diet can improve and maintain health, which can include aspects of mental and physical health. Specific diets, such as the DASH diet, can be used in treatment and management of chronic conditions. Dietar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colloquies
''Colloquies'' (Latin title ''Colloquia familiaria'') is one of the many works of the "Prince of Christian Humanists", Desiderius Erasmus. Published in 1518, the pages "...held up contemporary religious practices for examination in a more serious but still pervasively ironic tone".Coffin G. Judith, Stacey C. Robert. Western Civilizations, Ed16 Vol2. W. W. Norton & Company, 2008. pp.463 Christian Humanists viewed Erasmus as their leader in the early 16th century. Erasmus' works had greater meaning to those learned few who had a larger knowledge of Latin and Greek. Colloquies in Latin means a formal written dialogue, thus in his book Erasmus explores man's reaction to others in conversations. The ''Colloquies'' is a collection of dialogues on a wide variety of subjects. They began in the late 1490s as informal Latin exercises for Erasmus' own pupils. In about 1522 he began to perceive the possibilities this form might hold for continuing his campaign for the gradual enlightenment an ...

Wilhelm Traugott Krug
Wilhelm Traugott Krug (22 June 177012 January 1842) was a German philosopher and writer. He is considered to be part of the Kantian School of logic. Life Krug was born on June 22, 1770 near Wittenberg to a farming family. He studied at the University of Wittenberg under Franz Volkmar Reinhard and Karl Gottfried Jehnichen, at Jena under Karl Leonhard Reinhold, and at Göttingen. After finishing his studies, he was employed as an adjunct professor at the University of Wittenberg. From 1801 to 1804, Krug was professor of philosophy at Frankfurt (Oder), after which he succeeded Immanuel Kant in the chair of logic and metaphysics at the University of Königsberg. From 1809 till his death he was professor of philosophy at the University of Leipzig. He fought in the War of Liberation (1813–14) as captain of mounted chasseurs.

Élie Metchnikoff
Ilya Ilyich Mechnikov (russian: Илья Ильич Мечников; – 15 July 1916), also spelled Élie Metchnikoff, was a Russian zoologist best known for his pioneering research in immunology. Belkin, a Russian science historian, explains why Metchnikoff himself, in his Nobel autobiography – and subsequently, many other sources – mistakenly cited his date of birth as 16 May instead of 15 May. Metchnikoff made the mistake of adding 13 days to 3 May, his Old Style birthday, as was the convention in the 20th century. But since he had been born in the 19th century, only 12 days should have been added. He and Paul Ehrlich were jointly awarded the 1908 Nobel Prize in Physiology or Medicine "in recognition of their work on immunity". Mechnikov was born in modern-day Ukraine to a Romanian noble father and a Ukrainian-Jewish mother, lived and worked for many years on the territory of what was then the Russian Empire, and later on continued his career in France. Given this com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Michel Eugène Chevreul
Michel Eugène Chevreul (31 August 1786 – 9 April 1889) was a French chemist and centenarian whose work influenced several areas in science, medicine, and art. His early work with animal fats revolutionized soap and candle manufacturing and led to his isolation of the heptadecanoic (margaric), stearic, and oleic fatty acids. In the process, Chevreul became the first scientist to define the concept of a chemical compound and the first to formally characterise the nature of organic compounds; he is consequently considered a founder of modern organic chemistry. In the medical field, he was first to demonstrate that diabetics excrete glucose in the urine and to isolate creatine. He lived to 102 and was a pioneer in the field of gerontology. His theories of colour "provided the scientific basis for Impressionist and Neo-Impressionist painting." He is one of the 72 French scientists, mathematicians, and engineers whose names are inscribed on the Eiffel Tower; of those 72, Chevreu ...

Industrial Revolution
The Industrial Revolution was the transition to new manufacturing processes in Great Britain, continental Europe, and the United States, that occurred during the period from around 1760 to about 1820–1840. This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, the increasing use of steam power and water power, the development of machine tools and the rise of the mechanized factory system. Output greatly increased, and a result was an unprecedented rise in population and in the rate of population growth. Textiles were the dominant industry of the Industrial Revolution in terms of employment, value of output and capital invested. The textile industry was also the first to use modern production methods. The Industrial Revolution began in Great Britain, and many of the technological and architectural innovations were of British origin. By the mid-18th century, Britain was the world's leadi ...

Life Expectancy
Life expectancy is a statistical measure of the average time an organism is expected to live, based on the year of its birth, current age, and other demographic factors like sex. The most commonly used measure is life expectancy at birth (LEB), which can be defined in two ways. ''Cohort'' LEB is the mean length of life of a birth cohort (all individuals born in a given year) and can be computed only for cohorts born so long ago that all their members have died. ''Period'' LEB is the mean length of life of a hypothetical cohort assumed to be exposed, from birth through death, to the mortality rates observed at a given year. National LEB figures reported by national agencies and international organizations for human populations are estimates of ''period'' LEB. In the Bronze Age and the Iron Age, human LEB was 26 years; in 2010, world LEB was 67.2 years. In recent years, LEB in Eswatini (formerly Swaziland) is 49, while LEB in Japan is 83.

Death
Death is the irreversible cessation of all biological functions that sustain an organism. For organisms with a brain, death can also be defined as the irreversible cessation of functioning of the whole brain, including brainstem, and brain death is sometimes used as a legal definition of death. The remains of a former organism normally begin to decompose shortly after death. Death is an inevitable process that eventually occurs in almost all organisms. Death is generally applied to whole organisms; the similar process seen in individual components of an organism, such as cells or tissues, is necrosis. Something that is not considered an organism, such as a virus, can be physically destroyed but is not said to die. As of the early 21st century, over 150,000 humans die each day, with ageing being by far the most common cause of death. Many cultures and religions have the idea of an afterlife, and also may hold the idea of judgement of good and bad deeds in one's life ( h ...

Memory
Memory is the faculty of the mind by which data or information is encoded, stored, and retrieved when needed. It is the retention of information over time for the purpose of influencing future action. If past events could not be remembered, it would be impossible for language, relationships, or personal identity to develop. Memory loss is usually described as forgetfulness or amnesia. Memory is often understood as an informational processing system with explicit and implicit functioning that is made up of a sensory processor, short-term (or working) memory, and long-term memory. This can be related to the neuron. The sensory processor allows information from the outside world to be sensed in the form of chemical and physical stimuli and attended to various levels of focus and intent. Working memory serves as an encoding and retrieval processor. Information in the form of stimuli is encoded in accordance with explicit or implicit functions by the working memory processor. ...

Forgetting
Forgetting or disremembering is the apparent loss or modification of information already encoded and stored in an individual's short or long-term memory. It is a spontaneous or gradual process in which old memories are unable to be recalled from memory storage. Problems with remembering, learning and retaining new information are a few of the most common complaints of older adults. Studies show that retention improves with increased rehearsal. This improvement occurs because rehearsal helps to transfer information into long-term memory. Forgetting curves (amount remembered as a function of time since an event was first experienced) have been extensively analyzed. The most recent evidence suggests that a power function provides the closest mathematical fit to the forgetting function. Overview Failing to retrieve an event does not mean that this specific event has been forever forgotten. Research has shown that there are a few health behaviors that to some extent can prevent forge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
