OverallEdit
This time span is generally referred to as "middle age" and can be defined as the time of ages about 40–45 to about 60–65.<ref name="Oxford Dicionary">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="Merriam Webster">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Middle age Template:Webarchive.

Those in middle age continue to develop relationships and adapt to changes in relationships. Such changes are highly evident in the maturing relationships between growing or grown children and aging parents. Community involvement is fairly typical of this stage of adulthood,<ref name="Stern-2016">Template:Cite book</ref> as is continued career development.
Physical characteristicsEdit
Middle-aged adults may begin to show visible signs of aging. This process can be more rapid in women who have osteoporosis.Template:Cn Changes might occur in the nervous system. The ability to perform complex tasks remains intact. In the normal range of 45 to 55, women experience menopause, which ends natural fertility.<ref>Template:Cite book</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Menopause can have many side effects. Changes can occur to skin, and other changes may include a decline in physical fitness, including a reduction in aerobic performance, a decrease in maximal heart rate, and graying and loss of hair. Sensory sensitivity in middle-aged adults has been shown to be one of the lowest.<ref>Template:Cite journal</ref> These measurements are generalities, and people may exhibit changes at different rates and times.<ref>Template:Cite journal</ref>
Mortality rates can begin to increase, due mainly to health issues like heart problems, cancer, hypertension, and diabetes.<ref name="Stern-2016" /> Still, the majority of middle-aged people in industrialized nations can expect to live into old age.
Starting around age 35, pregnant women are considered to be of advanced maternal age, and significant declines in fertility begin to occur that usually end with menopause around age 50.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Middle-aged urban adults who are experiencing frailty and poverty show an association with increased H2O2 induced oxidative DNA damage.<ref>Template:Cite journal</ref>
CognitiveEdit
Erik Erikson refers to this period of adulthood as generativity versus stagnation, the seventh of eight stages of Erikson's stages of psychosocial development. People in middle age may experience some cognitive loss, which usually remains unnoticeable because life experiences and strategies get developed to compensate for any decrease in mental abilities.<ref>Template:Cite book</ref>
During this stage, adults often strive to have things that will outlast them. Generativity, which is the concern and the commitment middle-aged people have for future generations, is a big part of development during this stage.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Social and personality characteristicsEdit
For some, marital satisfaction remains intact, but other family relationships can become more difficult. Career satisfaction focuses more on inner satisfaction and contentedness and less on ambition and the desire to advance.<ref name="Stern-2016"/> Even so, career changes occur often. Middle age can be a time when people reexamine their lives by taking stock and evaluating their accomplishments. Morality may change and become more conscious.<ref>Template:Cite journal</ref> The perception that those in this stage of development of life undergo a so-called midlife crisis is a largely false one.<ref>Template:Citation</ref> Personality characteristics remain stable throughout this period,<ref name="PsycNet"/> and relationships in middle age may continue to evolve into connections that are stable.<ref name="Stern-2016"/>
