I was at my 50th high school reunion, the other day and it was fun to see people and to catch up and travel down memory lane. I was reminded of the fact that the only constant in life is change. People talked about their lives and the changes they went through. As they changed, they had to make many
adjustments, and these for some were unsettling. So I started thinking about age and wondered
how we in the world, define old age.
From the United Nations I
found this: “Most developed world countries have accepted the chronological age
of 65 years as a definition of 'elderly' or older person, but like many
westernized concepts, this does not adapt well to the situation in Africa.
While this definition is somewhat arbitrary, it is many times associated with
the age at which one can begin to receive pension benefits. At the moment,
there is no United Nations standard numerical criterion, but the UN agreed
cutoff is 60+ years to refer to the older population.”
Although there are commonly
used definitions of old age, it has changed over the years as far back as 1875,
in Britain, the Friendly Societies Act, enacted the definition of old age as,
"any age after 50"
In many parts of the
developing world, chronological time has little or no importance in the meaning
of old age. Other socially constructed meanings of age are more significant
such as the roles assigned to older people; in some cases it is the loss of
roles accompanying physical decline, which is significant in defining old age.
This transition from a
contributing member of society to a non-contributing member became the basis
for the definition of old age which occurred between the ages of 45 and 55
years for women and between the ages of 55 and 75 years for men.
Thus, in contrast to the
chronological milestones which mark life stages in the developed world, old age
in many developing countries is seen to begin at the point when active
contribution is no longer possible.
Study results published in
1980 provides a basis for a definition of old age in developing countries
(Glascock, 1980). This international anthropological study was conducted in the
late 1970's and included multiple areas in Africa. Definitions fell into three
main categories: 1) chronology; 2) change in social role (i.e. change in work
patterns, adult status of children and menopause); and 3) change in
capabilities (i.e. invalid status, senility and change in physical
characteristics). Results from this cultural analysis of old age suggested that
change in social role is the predominant means of defining old age.
From Wikipedia came this: A Pew Research
Center study of 2,929 Americans, age 18+, found that they hold very different
definitions of old age. Respondents up to early 30's said that old age begins
at 60, but respondents 65+ said 74
Most Britons define old age as starting at 59 according to a survey of
2,200 people in the UK. The under 25s reckon 54 as the beginning of old age.
The 80+ define old age as starting at 68. Another survey concluded that most Britons
define the onset of old age as almost 70. Europeans on average set the start of
old age at 62.
Physical marks of old age include the following:
- Bone and joint. Old bones are marked by “thinning and
shrinkage.” This results in a loss of height (about two inches by age 80),
a stooping posture in many people, and a greater susceptibility to bone
and joint diseases such as osteoarthritis and osteoporosis.
- Chronic diseases. Most older persons have at least one chronic
condition and many have multiple conditions. In 2007-2009, the most
frequently occurring conditiouns among older persons in the United States
were uncontrolled hypertension (34%), diagnosed arthritis (50%),
and heart disease (32%).
- Dental problems. Less saliva and less ability
for oral hygiene in old age increases the chance of tooth
decay and infection.
- Digestive system. About 40% of the time, old age is marked
by digestive disorders such as difficulty in swallowing, inability to eat
enough and to absorb nutrition, constipation and bleeding.
- Eyesight. Diminished eyesight makes it more
difficult to read in low lighting and in smaller print. Speed with which
an individual reads and the ability to locate objects may also be
impaired.
- Falls. Old age spells risk for injury from
falls that might not cause injury to a younger person Every year,
about one-third of those 65 years old and over half of those 80 years old
fall. Falls are the leading cause of injury and death for old people.
- Hair usually becomes thinner and grayer.
- Hearing. By age 75 and older, 48% of men and 37%
of women encounter impairments in hearing. Of the 26.7 million people over
age 50 with a hearing impairment, only one in seven uses a hearing aid.
- Hearts are less efficient in old age with a
resulting loss of stamina. In addition, atherosclerosis can constrict
blood flow.[
- Immune function. Less efficient immune function (Immunosenescence)
is a mark of old age
- Lungs expand less well; thus, they provide
less oxygen
- Pain afflicts old people at least 25% of the
time, increasing with age up to 80% for those in nursing homes.[ Most
pains are rheumatological or malignant.
- Sexual activity decreases significantly with age,
especially after age 60, for both women and men. Sexual drive in both men and
women decreases as they age.[
- Skin loses elasticity, becomes drier, and
more lined and wrinkled.[
- Sleep trouble holds a chronic prevalence of
over 50% in old age and results in daytime sleepiness In a study of
9,000 persons with a mean age of 74, only 12% reported no sleep complaints. By
age 65, deep sleep goes down to about 5%.
- Taste buds diminish so that by age 80 taste
buds are down to 50% of normal. Food becomes less appealing and
nutrition can suffer.
- Voice. In old age, vocal cords weaken and
vibrate more slowly. This results in a weakened, breathy voice that is
sometimes called an “old person’s voice.”
Mental marks of old
age include the following.
- Adaptable describes most people in their old age.
In spite the stressfulness of old age, they are described as “agreeable”
and “accepting.” However, old age dependence induces feelings of
incompetence and worthlessness in a minority.
- Caution marks old age. This antipathy toward
“risk-taking” stems from the fact that old people have less to gain and
more to lose by taking risks than younger people.
- Depressed mood. According to Cox, Abramson, Devine,
and Hollon (2012), old age is a risk factor for depression caused by
prejudice (i.e., “deprejudice”). When people are prejudiced against the
elderly and then become old themselves, their anti-elderly prejudice turns
inward, causing depression. “People with more negative age stereotypes
will likely have higher rates of depression as they get older.”
Old age depression results in the over-65 population having the
highest suicide rate.
- Fear of crime in old age, especially among
the frail, sometimes weighs more heavily than concerns about finances or
health and restricts what they do. The fear persists in spite of the fact
that old people are victims of crime less often than younger people.
- Mental disorders afflict about 15% of people aged 60+
according to estimates by the World Health Organization. Another
survey taken in 15 countries reported that mental disorders of adults
interfered with their daily activities more than physical problems.
- Reduced mental and cognitive ability afflicts old age.
Memory loss is common in old age due to the decrease in speed
of information being encoded, stored, and retrieved. It takes more time to
learn new information. Dementia
is a general term for memory loss and other intellectual abilities serious
enough to interfere with daily life. Its prevalence increases in old age
from about 10% at age 65 to about 50% over age 85. Alzheimer's
disease accounts for 50 to 80 percent of dementia cases. Demented
behavior can include wandering, physical aggression, verbal outbursts,
depression, and psychosis.
- Set in
one’s ways describes
a mind-set of old age. A study of over 400 distinguished
men and women in old age found a “preference for the routine.” Explanations
include old age’s toll on the “fluid intelligence” and the “more deeply
entrenched” ways of the old.
