Old age WikipediaOld people redirects here. For the Khmer Rouge term, see New People. Old age refers to ages nearing or surpassing the life expectancy of human beings, and is thus the end of the human life cycle. Terms and euphemisms include old people worldwide usage, seniors American usage, senior citizens British and American usages, older adults in the social sciences1, the elderly, and elders in many culturesincluding the cultures of aboriginal people. Old people often have limited regenerative abilities and are more susceptible to disease, syndromes, and sickness than younger adults. The organic process of ageing is called senescence,2 the medical study of the aging process is called gerontology,3 and the study of diseases that afflict the elderly is called geriatrics. The elderly also face other social issues around retirement, loneliness, and ageism. Old age is not a definite biological stage, as the chronological age denoted as old age varies culturally and historically. In 2. RebelMouse is the best CMS 2017 and 1 Wordpress VIP alternative.

United Nations proposed a human rights convention that would specifically protect older persons. DefinitionseditDefinitions of old age include official definitions, sub group definitions, and four dimensions as follows. Official definitionseditOld age comprises the later part of life the period of life after youth and middle age. At what age old age begins cannot be universally defined because it differs according to the context. Most developed world countries have accepted the chronological age of 6. How To Install Rpm Package On Arch Linux Packages. The United Nations has agreed that 6. However, for its study of old age in Africa, the World Health Organization WHO set 5.

Old age refers to ages nearing or surpassing the life expectancy of human beings, and is thus the end of the human life cycle. Terms and euphemisms include old people. The serotonin syndrome is a potentially lifethreatening drug reaction that may result from therapeutic medication use, selfpoisoning, or interactions between drugs. At the same time, the WHO recognized that the developing world often defines old age, not by years, but by new roles, loss of previous roles, or inability to make active contributions to society. Most developed Western countries set the age of 6. Being 6. 06. 5 years old is usually a requirement for becoming eligible for senior social programs. However, various countries and societies consider the onset of old age as anywhere from the mid 4. The definitions of old age continue to change especially as life expectancy in developed countries has risen to beyond 8. In October 2. 01. Nature presented the conclusion that the maximum human lifespan is an average age of 1. However, the authors methods and conclusions drew criticism from the scientific community, who concluded that the study was flawed. Sub group definitionseditGerontologists have recognized the very different conditions that people experience as they grow older within the years defined as old age. In developed countries, most people in their 6. However, after 7. Therefore, rather than lumping together all people who have been defined as old, some gerontologists have recognized the diversity of old age by defining sub groups. One study distinguishes the young old 6. Another studys sub grouping is young old 6. A third sub grouping is young old 6. Delineating sub groups in the 6. Two British scholars, Paul Higgs and Chris Gilleard, have added a fourth age sub group. In British English, the third age is the period in life of active retirement, following middle age. Higgs and Gilleard describe the fourth age as an arena of inactive, unhealthy, unproductive, and ultimately unsuccessful ageing. Dimensions of old ageeditKey Concepts in Social Gerontology lists four dimensions chronological, biological, psychological, and social. Wattis and Curran add a fifth dimension developmental. Chronological age may differ considerably from a persons functional age. The distinguishing marks of old age normally occur in all five senses at different times and different rates for different persons. In addition to chronological age, people can be considered old because of the other dimensions of old age. For example, people may be considered old when they become grandparents or when they begin to do less or different work in retirement. Senior citizeneditSenior citizen is a common euphemism for an old person used in American English, and sometimes in British English. It implies that the person being referred to is retired. This in turn usually implies that the person is over the retirement age, which varies according to country. Synonyms include old age pensioner or pensioner in British English, and retiree and senior in American English. Some dictionaries describe widespread use of senior citizen for people over the age of 6. When defined in an official context, senior citizen is often used for legal or policy related reasons in determining who is eligible for certain benefits available to the age group. It is used in general usage instead of traditional terms such as old person, old age pensioner, or elderly as a courtesy and to signify continuing relevance of and respect for this population group as citizens of society, of senior rank. The term was apparently coined in 1. Famed caricaturist Al Hirschfeld claimed on several occasion that his father Isaac Hirschfeld invented the term senior citizen. It has come into widespread use in recent decades in legislation, commerce, and common speech. Especially in less formal contexts, it is often abbreviated as seniors, which is also used as an adjective. In commerce, some businesses offer customers of a certain age a senior discount. The age at which these discounts are available varies between 5. Sometimes a special senior discount card or other proof of age needs to be obtained and produced to show entitlement. Age qualificationseditThe age which qualifies for senior citizen status varies widely. In governmental contexts, it is usually associated with an age at which pensions or medical benefits for the elderly become available. In commercial contexts, where it may serve as a marketing device to attract customers, the age is often significantly lower. In the United States, the standard retirement age is currently 6. In Canada, the OAS Old Age Security pension is available at 6. Conservative government of Stephen Harper had planned to gradually increase the age of eligibility to 6. Liberal government of Justin Trudeau is considering leaving it at 6. CPP Canada Pension Plan as early as age 6. The AARP allows couples in which one spouse has reached the age of 5. Marks of old ageeditThe distinguishing characteristics of old age are both physical and mental. The marks of old age are so unlike the marks of middle age that legal scholar Richard Posner suggests that, as an individual transitions into old age, heshe can be thought of as different persons time sharing the same identity. These marks do not occur at the same chronological age for everyone. Also, they occur at different rates and order for different people. Marks of old age can easily vary between people of the same chronological age. A basic mark of old age that affects both body and mind is slowness of behavior. This slowing down principle finds a correlation between advancing age and slowness of reaction and physical and mental task performance. However, studies from Buffalo University and Northwestern University have shown that the elderly are a happier age group than their younger counterparts. Physical marks of old ageeditPhysical marks of old age include the following Bone and joint. Old bones are marked by thinning and shrinkage. This might result in a loss of height about two inches 5 cm by age 8. What Would Aliens Look Like As the absurdity on our home planet grows, so does humanitys curiosity about life beyond 1 AU. Of course, wildly speculating about aliens is nothing new its been fueling many facets of science fiction for years. But recently proposed missions toOcean worlds that could harbor microbial life make the search for extraterrestrials less tinfoil hat like and a bit more tangible. If we did find alien life, it would be the biggest discovery in human history. Most sci fi tells us this will likely end poorly, but some of us choose to believe otherwise. If we keep an open mind and speculate wildly, some pretty interesting questions arisemost obviously, what the hell would aliens look like In this weeks Giz Asks, we spoke to astrobiologists about what extraterrestrial life might look like if we ever find it. Hopefully its more Arrival than Signs, but ultimately, Im rooting for space capybaras. Seth Shostak. Senior astronomer at the SETI Search for Extra Terrestrial Intelligence Institute. What do you think is the most unrealistic depiction of aliens according to pop culture Well, I prefer the aliens that seem to be pretty intelligent. The Daleks were among that distinguished set, but their general resemblance to industrial grade vacuum cleaners always inclined me to think that, as alien lifeforms go, they suck. And they were somehow considered to be mutants. Well, heck, were ALL mutants, but at least we can climb stairs. Whats the closest thing on Earth we have to aliens Among earthly life forms, the most alien, to my mind, are insects. When you just see them flit across a room or picnic table, theyre relatively unimpressive, even if annoying. But seen up close, they are truly alienutilitarian and ingenious. Also ugly, although I suppose if you were, like Gregor Samsa, also an insect, you might find them appealing. Caitlin Ahrens. Astronomer, physicist, and Ph. D candidate in Space and Planetary Sciences at the University of Arkansas. What are some destinations outside our solar system where scientists think we might be able to find lifeIf a planet is by a large enough star for light and is nestled within that stars Goldilocks zonenot too hot and not too cold for waterthen thats a good start However, as we are learning with Europa and Enceladus, its entirely possible to have subsurface oceans that would be warm enough to house life and yet be very frozen on the outer surface. Is it likely that life outside Earth would resemble anything we have here Ill put life in quotes due to it being a very vague term in regards to aliens. We have carbon based life. But theres theories for sulphur based and other chemistries to form some biological structures. Life could mean anything from microscopic blue cupcake loving worms to sentient snorkels that like polkanot necessarily human like. Not necessarily intelligent either. Doug Vakoch. President of METI International, which focuses on seeking out radio signals from intelligent extraterrestrial life. Obviously, we have yet to find life outside Earth. But if we did, what might it be similar to Tardigrades WhalesEvolution relies heavily on chance events, so theres no reason to expect that the history of life as weve seen it on Earth would play out the same on other planets. And yet, we see cases on our own world in which similar environments seem to pull for creatures that are built the same. Sharks and dolphins have similar body forms, though they are far distant relatives, one being a fish and the other a mammal. We should not be surprised to see a similar convergence of body shape when we encounter life on other worlds. But the particular combination of details that define each species on Earth could result in a suite of creatures that vary radically from planet to planet. The bottom line is that we should not expect to see a duplicate of Homo sapiens as we look for life beyond Earth. If we find life on the ocean worlds within our own solar system, how might it present itself How could it survive As we continue to explore our own solar system with robotic missions, we will be searching for signs of life indigenous to other planets and moons. Perhaps under the icy crust of Saturns moon Enceladus we will someday find evidence of microbial life, living off the energy provided by hydrothermal vents. But the waters of Enceladus are so bone chillingly cold that it would be hard to any imagine life there being much bigger than a bacterium. Might we find life on another moon of Saturn Titan is an intriguing possibility, with an atmosphere much denser than that of other moons, including carbon containing molecules. The apparent lack of liquid water on its surface is a strike against Titan for habitability, but pools of liquid ethane and methane may provide a critical crucible for life. Given that Titan is much further from the Sun than is Earth, its surface temperature is also much lower. Europas potential habitability hinges on the fact that its subsurface ocean shows signs of liquid water in direct contact with the moons mineral rich mantle. Another factor in favor of Europa as an abode of life is that it seems to be generating energy from within, which could support the metabolic processes of life. Although some of this internal energy may arise from radioactive decay, even more energy is likely to come from tidal flexing. All of these are promising signs, but is it sufficient to yield something like a tardigrade on Europa Lets be cautious, remembering that even on Earth, tardigrades are able to survive at the coldest temperatures and the greatest pressures for only a short time. As we seek out multicellular life on other worlds, it would need to be like a tardigrade on steroids, not only surviving a harsh environment for limited time, but being a true extremophile, thriving under conditions that are inconceivable for human beings. Are the gray aliens from pop culture a pretty unlikely representation of what intelligent life would look like How likely are any intelligent beings on other worlds to look like the gray aliens from pop cultureNot very. To find a humanoid form on another world, a whole series of unexpected events would have to been replicated. Early hominids adapted to a particular niche on the savannas of Africa, their upright posture letting them see stronger, fiercer predators at a distance. Under a different environment, having a brain at the top of the body might be a liability, with increased risk of damage by falling but with no great advantage to compensate. We see varied forms of intelligence on our own world. Octopuses are remarkably intelligent, but without controlling everything from a centralized brain. Instead, their smarts are largely distributed throughout their eight limbs. If we do make contact with intelligence on another planet, it means they have created radio or laser transmitters to signal us across the vast distances between the stars. But whether they did that with a pair of hands or a set of tentacles, we have no way of anticipating. Rocco Manicelli. Astrobiologist at NASAIf we do find life outside Earthlets say on a planet like Enceladushow big or small would it probably be I doubt that it would more than a single cell life form so the size would be comparable to a bacterium. The environment of Enceladus does not lend itself to support multi cellularity, in my opinion.
