a progressive, irreversible brain disorder that is characterized by a gradual deterioration of memory, reasoning, language, and eventually, physical function. In 2018, an estimated 5.7 million adults in the United States had it, and it is projected that 10 million baby boomers will develop it. Ten percent of individuals 65 and older have it. The percentage of individuals with it increases dramatically at older ages: 3 percent of 65- to 74-year-olds, 17 percent of 75- to 84-year-olds, and 32 percent of people 85 and older. --- are more likely than men to develop Alzheimer disease because they live longer than --- and their longer life expectancy increases the number of years during which they can develop it. It is estimated that Alzheimer disease --- the health-care costs of Americans 65 years of age and older

Alzheimer disease women men triples

Five drugs have been approved by the U.S. Food and Drug Administration (FDA) for the treatment of Alzheimer disease. Three of the medications, ---, ---, and ---, are cholinesterase inhibitors designed to improve memory and other cognitive functions by increasing levels of acetylcholine in the brain. A fourth drug, ---, regulates the activity of glutamate, which is involved in processing information. ---, a combination of memantine and donepezil, is the fifth approved medicine to treat Alzheimer disease; this medicine is designed to improve cognition and overall mental ability. A research review concluded that --- inhibitors do not reduce progression to dementia from mild cognitive impairment.

Aricept (donepezil) Razadyne (galantamine) Exelon (rivastigmine) Namenda (memantine) Namzatric cholinesterase

--- becomes relevant when life tasks require a level of capacity beyond the current level of the older adult's performance potential

Compensation

--- is associated with a number of other positive outcomes for older adults. For example, older adults with a higher level of this experience less cognitive decline as they age. Also, in older adults, higher levels of conscientiousness, openness to experience, agreeableness, and extraversion were linked to ---emotions, while neuroticism was associated with --- emotion

Conscientiousness positive negative

--- Successive generations in America's twentieth century were better educated, and this trend continues in the twenty-first century. Educational experiences are positively correlated with scores on intelligence tests and information-processing tasks, such as memory exercises. Also, one study found that older adults with a higher level of education had better cognitive functioning

Education

--- is the retention of information about the where and when of life's happenings. For example, what was the color of the walls in your bedroom when you were a child? What did you eat for breakfast this morning?

Episodic memory

---- increasingly is thought to be involved not only in cognitive performance but also in health, emotion regulation, adaptation to life's challenges, motivation, and social functioning. In one study, ---- but not memory predicted a higher risk of coronary heart disease and stroke three years later in older adults

Executive function

an umbrella-like concept that consists of a number of higher-level cognitive processes linked to the development of the brain's prefrontal cortex. It involves managing one's thoughts to engage in goal-directed behavior and to exercise self-control

Executive function

--- is memory of facts and experiences that individuals consciously know and can state. Also is sometimes called declarative memory. Examples include recounting the plot of a movie you have seen or being at a grocery store and remembering what you wanted to buy

Explicit memory

--- involves damage to the optic nerve because of the pressure created by a buildup of fluid in the eye. Approximately --- percent of individuals in their seventies and --- percent of those in their nineties have it, and it can be treated with eye drops. If left untreated, it can ultimately destroy a person's vision

Glaucoma 1 10

--- is memory without conscious recollection; it involves skills and routine procedures, such as driving a car or typing on a computer keyboard, that you perform without having to consciously think about what you are doing. It is less likely to be adversely affected by aging than explicit memory is

Implicit memory

In a classic study, --- and --- found that an important factor related to health, and even survival, in a nursing home is the patient's feelings of control and self determination. One group was encouraged to make more day-to-day choices and thus to feel they had more control over their lives. They began to decide such matters as what they ate, when their visitors could come, what movies they saw, and who could come to their rooms. Another group in the same nursing home was told by the administrator how caring the nursing home staff was and how much they wanted to help, but these residents were given no added responsibility over their lives. Eighteen months later, the residents who had been given extra responsibility were healthier, happier, and more alert and active than the residents who had not received added responsibility

Judith Rodin and Ellen Langer

New England Centenarian Study (NECS) compression of morbidity female male 11 17

The ---, directed by David Snowdon, is an intriguing ongoing investigation of aging in 678 nuns, many of whom are from the convent of the Sisters of Notre Dame in Mankato, Minnesota. They lead an intellectually challenging life, and brain researchers conclude that this contributes to their quality of life as older adults and possibly to their longevity. They also agreed to donate their brains for scientific research when they die, and they are the largest group of brain donors in the world

Nun Study

Highest ratio of centenarians in the world live in _____(_____ per every ____ inhabitants)

Okinawa 34.7 100,000

--- workers have lower rates of absenteeism, fewer accidents, and increased job satisfaction compared with their --- counterparts. This means that older workers can be of considerable value to a company, above and beyond their cognitive competence. Changes in federal law now allow individuals over the age of 65 to continue working in most jobs.

Older younger

---- suggests that it is possible to maintain performance in some areas through continued practice and the use of new technologies

Optimization

--- involves an extensive loss of bone tissue and is the main reason many older adults walk with a marked stoop. Women are especially vulnerable to it, which is the leading cause of broken bones in women . Approximately ---percent of cases in the United States occur in females, --- percent in males. Almost ---- of women over the age of 60 are affected by it. It is more common in non-Latina White, thin, and small-framed women. It is related to deficiencies in calcium, vitamin D, and estrogen, and to lack of exercise. Drugs such as Fosamax can be used to reduce the risk

Osteoporosis 80 20 2/3

Another type of dementia is ----, a chronic, progressive disorder characterized by muscle tremors, slowing of movement, and partial facial paralysis. Parkinson disease is triggered by degeneration of --- in the brain. Dopamine is a neurotransmitter that is necessary for normal brain functioning. Why these neurons degenerate is not known

Parkinson disease dopamine-producing neurons

In the view of --- and his colleagues, the selection of domains and life priorities is an important aspect of development. Life goals and personal life investments likely vary across the life course for most people. For many individuals, it is not just the sheer attainment of goals, but rather the attainment of meaningful goals, that makes life satisfying

Paul Baltes

the amount of time it takes to perform simple perceptual-motor tasks such as deciding whether pairs of two-digit or two-letter strings are the same, or how long it takes someone to step on the brakes when the car directly ahead stops. It shows considerable decline in late adulthood, and it is strongly linked with decline in working memory

Perceptual speed

Distinguished aging researcher --- argues that the life review is set in motion by looking forward to death. Sometimes the life review proceeds ---; at other times it is ---, requiring considerable work to achieve some sense of personality integration. The life review may be observed initially in stray and insignificant thoughts about oneself and one's life history. These thoughts may continue to emerge in brief intermittent spurts or become essentially continuous

Robert Butler quietly intense

--- is based on the concept that older adults have a reduced capacity and loss of functioning, which require a reduction in performance in most life domains

Selection

--- theory states that successful aging is linked with three main factors (SOC). The theory describes how people can produce new resources and allocate them effectively to the tasks they want to master

Selective optimization with compensation

--- is a person's knowledge about the world. It includes a person's fields of expertise, general academic knowledge of the sort learned in school, and "everyday knowledge" about the meanings of words, important places, and common things. Older adults often take longer to retrieve semantic information, but usually they can ultimately retrieve it. However, the ability to retrieve very specific information (such as names) usually declines in older adults

Semantic memory

when the Stanford Center on Longevity conducted a recent large-scale examination of healthy living in different age groups called the ---, social engagement with individuals and communities appeared to be weaker today than it was --- years ago for 55- to 64-year-olds. Many of these individuals, who are about to reach retirement age, had weaker relationships with spouses, partners, family, friends, and neighbors than their counterparts of 15 years ago

Sightlines Project 15

---- challenges the stereotype that the majority of older adults are in emotional despair because of their social isolation. Rather, older adults consciously choose to decrease the total number of their social contacts in favor of spending increased time in emotionally rewarding moments with friends and family

Socioemotional selectivity theory

---- states that older adults become more selective about their social networks. Because they place a high value on emotional satisfaction, older adults spend more time with familiar individuals with whom they have had rewarding relationships. Developed by ----, this theory argues that older adults deliberately withdraw from social contact with individuals peripheral to their lives while they maintain or increase contact with close friends and family members with whom they have had enjoyable relationships. This selective narrowing of social interaction maximizes positive emotional experiences and minimizes emotional risks as individuals become older

Socioemotional selectivity theory Laura Carstensen

The Stanford Center for Longevity (2011) and together the ---- (2014) reported information based on a consensus of leading scientists in the field of aging on how successfully the cognitive skills of older adults can be improved. One of their concerns is the misinformation given to the public touting products to improve the functioning of the mind for which there is no ---. For example, nutritional supplements have been advertised as "magic bullets" to slow the decline of mental functioning and improve the mental ability of older adults. Some of the claims are reasonable but not scientifically tested, while others are unrealistic and implausible

Stanford Center for Longevity and the Max Planck Institute for Human Development scientific evidence

--- generations have also had work experiences that included a stronger emphasis on cognitively oriented labor. Our great-grandfathers and grandfathers were more likely to be manual laborers than were our fathers, who are more likely to be involved in cognitively oriented occupations. Researchers have found that when older adults engage in complex working tasks and challenging daily work activities their cognitive functioning shows less age-related decrease. These generations have also been healthier in late adulthood as more effective treatments for a variety of illnesses (such as hypertension) have been developed. Many of these illnesses, such as stroke, heart disease, and diabetes, have a negative impact on intellectual performance

Successive

the ability to focus attention on a selected stimulus for a prolonged period of time. Researchers have found that older adults often perform as well as middle-aged and younger adults on measures of it. However, consistency of attention is important. A study of older adults found that the greater the --- in their --- attention (vigilance), the more likely they were to experience falls

Sustained attention variability

Once destruction of brain tissue occurs from Alzheimer disease, it is unlikely that treatment of the disease will reverse the damage, at least based on the state of research now and in the foreseeable future. Alzheimer disease involves a deficiency in the brain messenger chemical ---, which plays an important role in memory. Also, as Alzheimer disease progresses, the brain --- and deteriorates. This deterioration is characterized by the formation of --- (dense deposits of protein that accumulate in the blood vessels) and --- (twisted fibers that build up in neurons). Neurofibrillary tangles consist mainly of a protein called ---. Currently, there is considerable research interest in the roles that amyloid and tau play in Alzheimer disease

acetylcholine shrinks amyloid plaques neurofibrillary tangles tau

Comparative information about African Americans, Latinos, and non-Latino Whites indicates a possible double jeopardy for elderly ethnic minority individuals who face problems related to both --- and ---

ageism racism

A gene called --- is linked to an increasing presence of plaques and tangles in the brain. Special attention has focused on an --- (an alternative form of a gene) labeled --- that is a strong risk factor for Alzheimer disease. More than 60 percent of individuals with Alzheimer disease have at least one --- allele, and females are more likely to have this allele than males. Indeed, the gene is the strongest genetic predictor of late-onset (65 years and older) Alzheimer disease (. Despite links between the presence of that gene and Alzheimer disease, less than --- percent of individuals who carry the gene develop dementia in old age

researchers have found that visual decline in late adulthood is linked to (a) --- decline, as well as (b) having fewer --- and engaging in less --- social/leisure activities

cognitive social contacts challenging

The field of --- has emerged as the major discipline that studies links between brain activity and cognitive functioning. This field especially relies on brain-imaging techniques, such as fMRI, PET, and DTI (diffusion tensor imaging) to reveal the areas of the brain that are activated when individuals engage in certain cognitive activities. For example, as an older adult is asked to encode and then retrieve verbal materials or images of scenes, the older adult's brain activity will be monitored by an fMRI brain scan.

cognitive neuroscience

Individuals often lose the ability to care for themselves and may become unable to recognize familiar surroundings and people—including family members. It is estimated that --- percent of women and --- percent of men 85 years and older are at risk for developing dementia

dementia 23 17

Research indicates that --- (deterioration in the myelin sheath that encases axons and is associated with information processing) occurs with aging in the brains of older adults

demyelination

--- growth can occur in human adults, possibly even in older adults. Recall that --- are the receiving portion of the neuron. One study compared the brains of adults at various ages (Coleman, 1986). From the forties through the seventies, the growth of dendrites ---. However, in people in their nineties, dendritic growth ---

dendritic dendrites increased stopped

In the last decade, scientists have tried to fill in a gap in cellular clock theory. Hayflick did not know why cells ---. The answer may lie at the tips of chromosomes. Each time a cell divides, ----, which are DNA sequences that cap chromosomes, become shorter and shorter. After about --- or --- replications, the telomeres are dramatically reduced, and the cell no longer can reproduce. One study revealed that healthy centenarians had ____ telomeres than unhealthy centenarians. Further, a recent study confirmed that ____ telomere length was linked to Alzheimer disease

die chromosomes telomeres 70 80 longer shorter

The main treatment for Parkinson disease involves administering drugs that enhance the effect of dopamine (---) in the disease's earlier stages and later administering the drug ---, which is converted by the brain into dopamine. However, it is difficult to determine the correct level of dosage of L-dopa, and the medication loses its efficacy over time. Another treatment for advanced Parkinson disease is ---, which involves implantation of electrodes within the brain. The electrodes are then stimulated by a pacemaker-like device. Stem cell transplantation and gene therapy also offer hope for treating Parkinson disease

Overeating is linked with an increase in ---, and researchers have found that --- —a diet low in calories but adequate in proteins, vitamins, and minerals—reduces the oxidative damage created by free radicals. In addition to diet, researchers also are exploring the role that --- might play in reducing oxidative damage in cells. A study of obese men found that endurance exercise reduced their oxidative damage

Paul Baltes and his colleagues have reached the following conclusions: (1) --- levels of wisdom are rare. --- people, including older adults, attain a high level of wisdom. That only a small percentage of adults show wisdom supports the contention that it requires experience, practice, or complex skills. (2) Factors other than age are critical for wisdom to develop to a high level. For example, certain life ---, such as being trained and working in a field involving difficult life problems and having wisdom-enhancing mentors, contribute to higher levels of wisdom. Also, people higher in wisdom have values that are more likely to consider the welfare of --- than their own happiness. (3) Personality-related factors, such as openness to experience, ---, and ---, are better predictors of wisdom than cognitive factors such as intelligence.

It also is now accepted that neurogenesis can occur in human adults. However, researchers have documented neurogenesis in only two brain regions: the ---, which is involved in memory, and the ---, which is involved in smell. It also is not known what functions these new brain cells perform, and at this point researchers have documented that they last for only several ---

--- argues that aging in the body's hormonal system can lower resistance to stress and increase the likelihood of disease. Normally, when people experience stressors, the body responds by releasing certain hormones. As people age, the hormones stimulated by stress remain at --- levels longer than when people were younger. These prolonged, elevated levels of stress-related hormones are associated with increased risks for many diseases, including cardiovascular disease, cancer, diabetes, and hypertension. Researchers are exploring stress-buffering strategies, including ---, in an effort to find ways to attenuate some of the negative effects of stress on the aging process

hormonal stress theory elevated exercise

In older adults, 64 percent of men and 69 percent of women 65 to 74 years of age have --- (high blood pressure). Consistent blood pressures above --- should be treated to reduce the risk of heart attack, stroke, or kidney disease. Various drugs, a healthy diet, and exercise can reduce the risk of cardiovascular disease in older adults

hypertension 120/80

Recently, a variation of hormonal stress theory has emphasized the contribution of a decline in --- functioning with aging. In a recent study, the percentage of --- (a type of white blood cell essential for immunity) decreased in older adults in their seventies, eighties, and nineties. Aging contributes to immune system deficits that give rise to infectious diseases in older adults. The extended duration of stress and diminished restorative processes in older adults may accelerate the effects of aging on immunity

immune system T cells

Scientists have accumulated considerable evidence that calorie restriction (CR) in laboratory animals can --- the animals' life spans. Research indicates that calorie restriction (CR) slows RNA decline during the aging process. Animals that are fed diets restricted in calories, although adequate in protein, vitamins, and minerals, live as much as --- percent longer than animals that have unlimited access to food

Socioemotional selectivity theory also focuses on the types of goals that individuals are motivated to achieve. Two important classes of goals are (1) --- related and (2) ---related. The trajectory of motivation for ---related goals starts relatively high in the early years of life, peaks in adolescence and early adulthood, and then declines in middle and late adulthood. The --- related trajectory is high during infancy and early childhood, declines from middle childhood through early adulthood, and increases in middle and late adulthood. In a recent commentary, --- noted that when older adults focus on emotionally meaningful goals, they are more satisfied with their lives, feel better, and experience fewer negative emotions

Six factors are most likely to predict high status for older adults in a culture: Older persons have valuable ---. Older persons control key --- resources. Older persons are permitted to engage in useful and valued ---as long as possible. Age-related --- changes involve greater responsibility, authority, and advisory capacity. The extended family is a common family arrangement in the culture, and the older person is integrated into the ---. In general, respect for older adults is greater in --- cultures (such as China and Japan) than in individualistic cultures (such as the United States). However, some researchers are finding that this collectivistic/individualistic difference in respect for older adults is not as strong as it used to be and that, in some cases, older adults in individualistic cultures receive considerable respect

Changes in --- may provide one type of adaptation in aging adults. Recall that --- is the specialization of function in one hemisphere of the brain or the other. Using neuroimaging techniques, researchers found that brain activity in the prefrontal cortex is lateralized --- in older adults than in younger adults when they are engaging in cognitive tasks. For example, Figure 2 shows that when younger adults are given the task of recognizing words they have previously seen, they process the information primarily in the --- hemisphere(s); older adults are more likely to use --- hemisphere(s). The decrease in lateralization in older adults might play a compensatory role in the aging brain. That is, using both hemispheres may improve the cognitive functioning of older adults.

____ is the number of years that the average person born in a particular year will probably live. The average life expectancy of individuals born in 2017 in the United States was ____ years. Sixty-five-year-olds in the United States today can expect to live an average of ____ more years (____for females, ____for males). People who are 100 years of age can only expect to live an average of ____ years longer

life expectancy 79 19.5 20.6 18.4 2.3

_____, the maximum number of years an individual can live, has remained steady at approximately ____ to ____ years of age.

Among the factors that are associated with living to be 100 are ____ and the ability to cope effectively with ____

longevity genes stress

The --- is a cellular pathway that involves the regulation of growth and metabolism. TOR stands for "---," and in mammals it is called mTOR. --- is a naturally derived antibiotic and immune system suppressant/modulator, first discovered in the 1960s on Easter Island. It has been commonly used and is FDA approved for preventing --- rejection and in --- transplants. Recently, proposals have been made that the mTOR pathway has a central role in the life of cells, acting as a cellular router for growth, protein production/ metabolism, and stem cell functioning. Rapamycin has not been approved as an anti-aging drug and has some serious side effects, including increased risk of infection and lymphoma, a deadly cancer. Some critics argue that scientific support for sirtuins and the mTOR pathway as key causes of aging in humans has not been found and that research has not adequately documented the effectiveness of using drugs such as rapamycin to slow the aging process or extend the human life span

Activity theory suggests that many individuals will achieve greater life satisfaction if they continue their --- roles into --- . If these roles are stripped from them (as in early retirement), it is important for them to find substitute roles that keep them active and involved.

middle-adulthood late adulthood

---- is linked to reproductive fitness, which is present only in the earlier part of adulthood. For example, consider Alzheimer disease, an irreversible brain disorder, which does not appear until late middle adulthood or late adulthood. According to evolutionary theory, possibly if Alzheimer disease occurred earlier in development, it might have been eliminated many centuries ago

natural selection

Researchers have found that ---, the generation of new neurons, does occur in lower mammalian species, such as mice. Also, research indicates that exercise and an enriched, complex environment can generate new --- in rats and mice, and that stress reduces their survival rate. For example, in a recent study, mice in an enriched environment learned more flexibly because of adult --- . One study revealed that coping with stress stimulated hippocampal neurogenesis in adult monkeys (Lyons & others, 2010). And researchers have discovered that if rats are cognitively challenged to learn something, new brain cells survive ---

As we have discussed aging, it should be apparent that there are large individual differences in the patterns of change for older adults. The most common pattern is ---, which characterizes most individuals. Their psychological functioning often peaks in early midlife, plateaus until the late fifties to early sixties, then modestly declines through the early eighties, although marked decline often occurs prior to death. Another pattern involves ---, which characterizes individuals who in late adulthood show greater than average decline. These individuals may have mild cognitive impairment in early old age, develop Alzheimer disease later, or have chronic disease that impairs their daily functioning. A third pattern of change in old age is ---, which characterizes individuals whose physical, cognitive, and socioemotional development is maintained longer than for most individuals and declines later than for most people

There is increasing interest in the role that --- might play in Alzheimer disease . It occurs when the body fails to defend itself against free-radical attacks and oxidation

oxidative stress

In a study of individuals from 18 to 94 years of age, as they grew older they had fewer ---- but retained close relationships with people who provided them with emotional support

peripheral social contacts

In other research, --- emotions increased and --- emotions (except for ---) decreased from 50 years of age through the mid-eighties

positive negative sadness

The --- is one area that shrinks, and research has linked this shrinkage with a decrease in working memory and other cognitive activities in older adults. The --- regions of the brain—such as the primary visual cortex, primary motor cortex, and somatosensory cortex—are less vulnerable to the aging process. A general slowing of function in the --- and --- begins in middle adulthood and accelerates in late adulthood. Both physical coordination and intellectual performance are affected. For example, after age 70 many adults no longer show a --- reflex, and by age 90 most --- are much slower. Slowing of the brain can impair the performance of older adults on intelligence tests, especially timed tests

In working with older clients, some clinicians use ---, which involves discussing past activities and experiences with another individual or group. Therapy may include the use of photographs, familiar items, and video/audio recordings. It can improve the mood and quality of life of older adults, including those with dementia. In a study with older adults who had dementia, it reduced their depressive symptoms and improved their self-acceptance and positive relations with others

Why can women expect to live longer than men? Social factors such as health attitudes, habits, lifestyles, and occupation are probably important. Men are more likely than women to die from most of the leading causes of death, including cancer of the ____, _____ accidents, ____ of the liver, ____, and ____ disease. These causes of death are associated with lifestyle. For example, the sex difference in deaths due to lung cancer and emphysema occurs because men are heavier ____ than women. However, women are more likely than men to die from some diseases such as ____ disease and some aspects of cardiovascular disease, such as ____-related problems

respiratory system motor vehicle cirrhosis emphysema coronary heart smokers alzheimer hypertension

Leading expert Phyllis Moen (2007) described how today, when people reach their sixties, the life path they follow is less clear: (1) some individuals don't --- from their careers; (2) some retire from their career work and then take up a --- job; (3) some retire from career jobs but do --- work; (4) some retire from a --- job and go on to yet another job; (5) some move in and out of the workforce, so they never really have a "---" job from which they retire; (6) some individuals who are in poor health move to a --- status and eventually into retirement; and (7) some who are laid off define it as "---"

retire new volunteer post retirement career disability retirement

----, which consists of focusing on a specific aspect of experience that is relevant while ignoring others that are irrelevant, generally decreases in older adults. For example, a recent study found that selective attention deficits were linked to older adults' less competent driving . However, on simple tasks involving a search for a feature, such as determining whether a target item is present on a computer screen, age differences are minimal when individuals are given sufficient practice

selective attention

In a recent study of individuals from 22 to 94 years of age, on days when middle-aged and older adults, as well as individuals who were less healthy, used more ---- strategies, they reported a higher level of happiness

selective optimization with compensation

In recent years, the term --- has often been used to describe perceived control over the environment and the ability to produce positive outcomes

self-efficacy

In the --- model of social relations, individuals go through life embedded in a personal network of individuals to whom they give, and from whom they receive, social support. Social support can help individuals of all ages cope more effectively with life's challenges. For older adults, social support is related to their physical health, mental health, and life satisfaction. For example, a recent study found that a higher level of social support was associated with older adults' increased life satisfaction. Social support also decreases the probability that an older adult will be institutionalized or become depressed

social convoy

To capitalize on the high presence of ____ in cancerous cells, researchers currently are investigating gene therapies that inhibit telomerase and lead to the death of cancerous cells while keeping healthy cells alive. A recent focus of these gene therapies is on ---- and their renewal. Telomeres and telomerase are increasingly thought to be key components of the stem cell regeneration process, providing a possible avenue to restrain cancer and delay aging

telomerase stem cells

adult daughters are --- times more likely than adult sons to give parents assistance with daily living activities

---- is closely linked to short-term memory but places more emphasis on memory as a place for mental work. Explanation of the decline of it in older adults focuses on their less efficient inhibition in preventing irrelevant information from entering it and their increased distractibility

working memory

In late adulthood, the changes in physical appearance that began occurring during middle age become more pronounced. --- and --- are the most noticeable changes. We also get --- as we get older. Both men and women become shorter in late adulthood because of bone loss in their ---. Our weight usually drops after we reach --- years of age. This likely occurs because we lose muscle, which also gives our bodies a "sagging" look

The United States is no longer a ____society. As more individuals are living past age 65, the proportion of individuals at different ages has become increasingly ____. Indeed, the concept of a period called "____," beginning in the sixties or seventies and lasting until death, is relatively new. Before the twentieth century, most individuals died before they reached ____
