==Overview==<br />
<br />
'''Old age''' consists of ages nearing or surpassing the [[average life span]] of [[human being]]s, and thus the end of the human [[biological life cycle|life cycle]]. [[Euphemism]]s and terms for older people include '''seniors''' — chiefly an American usage — or '''elderly'''. Some believe there to be prejudice against older people in Western cultures, which is one form of [[ageism]].<br />
<br />
Older people have limited regenerative abilities and are more prone to disease, syndromes, and sickness than other [[adult]]s. For the [[biology]] of [[ageing]], see [[Senescence]]. The medical study of the aging process is [[gerontology]], and the study of diseases that afflict the elderly is [[geriatrics]].<br />
<br />
==Definition==<br />
The boundary between [[middle age]] and old age cannot be defined exactly because it does not have the same meaning in all societies. In many parts of the world, people are considered old because of certain changes in their activities or social roles. Examples: people may be considered old when they become [[grandparent]]s, or when they begin to do less or different work — [[retirement]]. In the United States and Europe, people are often considered old if they have lived a certain number of years. <br />
<br />
Many Americans think of 65 as the beginning of old age because United States workers become eligible at this time to retire with full [[Social Security (United States)|Social Security]] benefits at age 65. People in the 65-and-over age group are often called ''senior citizens''. In [[2003]], the age at which an American citizen becomes eligible for full Social Security benefits began to increase gradually until it reaches 67 in [[2027]]. <br />
<br />
There are many [[stereotypes]] about elderly people, such as; the use of walking sticks, frequent doctor visits, and sleeping a lot. These can be seen however to be untrue and very judgmental, most old people are very capable of easy mobility and caring for themselves, however there are some illnesses that can be seen to come with old age.<br />
<br />
==Demographic changes== <br />
Worldwide, the number of people 65 or older is increasing faster than ever before. Most of this increase is occurring in [[developed countries]]. In the United States the percentage of people 65 or older increased from 4 percent in [[1900]] to about 13 percent in the [[1998|late 1990s]]. In 1900, only about 3 million of the nation's citizens had reached 65. By 1998, the number of senior citizens had increased to about 34 million. Population experts estimate that more than 50 million Americans — about 17 percent of the population — will be 65 or older in 2020. The number of old people is growing around the world chiefly because more children reach adulthood.<!-- NEEDS WORK: these statements need a verifiable reference; and this looks like a good spot for a graph --><br />
<br />
==Life expectancy==<br />
In most parts of the world, women live, on average, longer than men. In the United States in the late 1990s, [[life expectancy]] at birth was 80 years for women and 77 years for men. American women who were age 65 in the late 1990s could expect to live about 19 additional years. Men who were 65 could expect to live about 16 additional years. <br />
