Gerontology Gerontology Ageing or aging is the process of becoming older. This article focuses on the social, cultural, and economic effects of ageing. The biology of ageing is treated in detail in senescence. ...more on Wikipedia about "Ageing"
(Aging (senescence)) In biology, senescence is the combination of processes of deterioration which follow the period of development of an organism. For the science of the care of the elderly, see gerontology; for experimental gerontology, see life extension. The word senescence is derived from the Latin word senex, meaning "old man" or "old age." ...more on Wikipedia about "Aging (senescence)"
The American Aging Association (AGE) is a non-profit, tax-exempt biogerontology organization of scientists and laypeople dedicated to biomedical aging studies intended to slow the aging process. The abbreviation AGE is intended to be representative of the organization, even though it is not an acronym. ...more on Wikipedia about "American aging association"
Calorie restriction or Caloric restriction (CR) is the practice of limiting dietary energy intake to improve health and retard aging. In human subjects, CR has been shown to lower cholesterol and blood pressure. Some consider these to be biomarkers of aging, as such diseases are more frequent with increasing age. Every animal species tested with CR so far, including primates, rats, spiders and rotifers, has shown corresponding lifespan extension. CR is the only known dietary measure capable of extending maximum lifespan, as opposed to average lifespan. Energy intake must be minimized, but sufficient quantities of vitamins, minerals and other important nutrients must still be ingested. To emphasize this, CR is often referred to by a plethora of other names such as CRON or CRAN (calorie restriction with optimal/adequate nutrition), or the "high-low diet" (high in all nutrients aside from calories, in which it is "low"). Other names for the diet emphasize the goal of the diet, such as CRL (calorie restriction for longevity), or simply The Longevity Diet, as in a recently published book by that name. ...more on Wikipedia about "Calorie restriction"

(a) publishing an article about de Grey by Sherwin B. Nuland, a professor of clinical surgery at Yale, and the author of How We Die. Titled Do You Want to Live Forever? , the story was resented by those predisposed to take de Grey seriously. ...more on Wikipedia about "De Grey Technology Review controversy"
DNA repair is a process constantly operating in cells; it is essential to survival because it protects the genome from damage and harmful mutations. In human cells, both normal metabolic activities and environmental factors (such as UV rays) can cause DNA damage, resulting in as many as 500,000 individual molecular lesions per cell per day. These lesions cause structural damage to the DNA molecule, and can dramatically alter the cell's way of reading the information encoded in its genes. Consequently, the DNA repair process must be constantly operating, to correct rapidly any damage in the DNA structure. ...more on Wikipedia about "DNA repair"

The free-radical theory of aging is that organisms age because cells accumulate free radical damage with the passage of time. For most biological structures free radical damage is closely associated with oxidation damage. Oxidation and reduction are redox chemical reactions. Most people can equate to oxidation damage as they are familiar with the process of rust formation of iron exposed to oxygen. Oxidation does not necessarily involve oxygen, after which it was named, but is most easily described as the loss of electrons from the atoms and molecules forming such biological structures. The inverse reaction, reduction, occurs when a molecule gains electrons. As the name suggests, antioxidants like vitamin C prevent oxidation and are often electron donators. ...more on Wikipedia about "Free-radical theory"
Geriatric sexology is the systematic study of sexuality in the elderly. It encompasses all aspects of sexuality, including attempting to characterise "normal sexuality" and its variants, including paraphilias and disorders of or relating to sex and the sex organs. The field covers physiological and psychological aspects of sexuality and its disorders. ...more on Wikipedia about "Geriatric sexology"

Hospice chaplains or geriatrics chaplains are, simply, chaplains often assigned by or working with hospitals, seminaries or volunteer organisations, that specialise in providing long-term spiritual care, especially to geriatric patients and those suffering from terminal illness. ...more on Wikipedia about "Hospice chaplain"
The Leonard Davis School of Gerontology at The University of Southern California, a leader in the field of gerontology, has pioneered educational programs including the world's first Ph.D. in Gerontology, the first joint Master's degree in Gerontology and Business Administration, and the first undergraduate Health Science Track in Gerontology. ...more on Wikipedia about "Leonard Davis School of Gerontology"
Life expectancy is the average number of years remaining for a living being (or the average for a class of living beings) of a given age to live. Life expectancy is also called average life span or mean life span, in particular distinction to maximum life span (the life span of the most long lived members of a class of living beings). ...more on Wikipedia about "Life expectancy"
Life extension refers to an increase in maximum lifespan or average lifespan, especially in mammals. Average lifespan is determined by vulnerability to accidents and age-related afflictions such as cancer or cardiovascular disease. Extension of average lifespan can be achieved by good diet, exercise and avoidance of hazards such as smoking and excessive eating of sugar-containing foods. Maximum lifespan is determined by the rate of aging of a species. Currently, the only widely recognized method of extending maximum lifespan is by calorie restriction with adequate nutrition. ...more on Wikipedia about "Life extension"

Description: Henry Gray's Anatomy of the Human Body, commonly known as Gray's Anatomy, is an anatomy textbook widely regarded as a classic work on human anatomy. The book was first published under the title Gray's Anatomy: Descriptive and Surgical in Great Britain in 1858, and the following year in the United States. The book's British author died after the publication of the 1860 second edition, at the age of 34, but his much-praised book was continued by others and on November 24, 2004, the 39th British edition was released. ...more on Wikipedia about "List of publications in biology"
Longevity is long life or existence. Reflections on longevity have usually gone beyond acknowledging the basic shortness of human life and included thinking about, and conceiving, methods to extend life (indefinitely). Longevity has been a topic not only for the scientific community but also for writers of travel, science fiction and utopian novels. The record human lifespan that has been authenticated is the 122 years 164 days of Jeanne Calment, though fiction, legend, and mythology have proposed or claimed vastly longer lifespans in the past or future and longevity myths frequently allege them to exist in the present. ...more on Wikipedia about "Longevity"
Maximum life span is a measure of the maximum number of years a member of a group can be expected to survive. Maximum life span corresponds to the age at which the oldest known member of a species or experimental group has died. Mean life span ( average lifespan or life expectancy) corresponds to the age at which half of a species or experimental group is still alive (measured from time of birth). In animal studies, maximum life span is typically taken to be the mean life span of the most long-lived 10%. ...more on Wikipedia about "Maximum life span"
The Methuselah Mouse Prize is a growing $3 million prize started in 2003 to accelerate research into slowing and eventually reversing cellular aging and breakdown in humans. The Methuselah Foundation awards prizes to researchers who extend the lifespan of a mouse to unprecedented lengths. The prize is named after Methuselah, a patriarch in the Bible said to have reached 969 years of age. ...more on Wikipedia about "Methuselah Mouse Prize"
Rejuvenation is the procedure of reversing the aging process, thus regaining youth. As people get older, their health worsens, strength and intelligence diminishes, beauty goes away. Historically, people in all societies have looked for a way to regain the qualities of youth. In the future however, rejuvenation may become reality through stem cells, biochemical repair or nanotechnology. ...more on Wikipedia about "Rejuvenation (aging)"
