ageingaging"Grow old along with me!" "The best is yet to be" [Robert Browning Rabbi Ben Ezra] ageingage outage in placeaging in placeage out (of something)age outageingageing, agingageingthe chronological process of growing physically older. However, there is also a social dimension in which chronology is less important than the meanings attached to the process. Different cultural values and social expectations apply according to gender and age group, and therefore there are socially-structured variations in the personal experience of ageing.EISENSTADT (Generation to Generation, 1964) studied the political role of age groups and argued that age stratification is an important stabilizing influence in societies where:
In DEMOGRAPHY the terms ageing society and youthful society are used to indicate the age composition of the population. A youthful society is one in which there is a preponderance of people in young age groups (under 15 years) because of a high BIRTH RATE and low LIFE EXPECTANCY. An ageing society is one in which reductions in the birth rate and greater longevity have resulted in a rising proportion of the population belonging to the older age groups. For example, CENSUS data for the UK shows that in 1911 men over 65 years and women over 60 years comprised 6.8% of the population, whereas in 1981 they comprised 17.1%. The growing proportion of older people in the population, and the spread of early retirement, has led to age being perceived as a social problem. Older people are subject to negative stereotyping and diminished SOCIAL STATUS. Even academic discourse promotes negative imagery through such terms as ‘burden of dependency’ and ‘dependency ratio’, which refer to the number of economically inactive older people in relation to the number of economically active younger people whose labour provides the services consumed by the older generation. In the US, AGEISM has become a political issue through the emergence of movements, such as the Grey Panthers, determined to safeguard the citizen rights of older people and counter the negative imagery of old age promoted by the commercialization of youth.

Ageing effects (e.g., patchy hyperpigmentation, fine wrinkles, telangiectasias) result from intrinsic and extrinsic processes and reflect the physicaleffects of the passage of time. Ageing skin is usually associated with a sagging face, in which deeper tissues (i.e., subjacent soft tissue) and structural landmarks lose their resiliency.Geriatrics A multifaceted process in which bodily structures and functions undergo a negative deviation from the optimum. Ageing phenomena include decreases in memory, muscle strength, muscle mass, manual dexterity, cardiac output, and auditory and visual acuity, as well as loss or thinning of hair. Other ageing phenomena include increased body fat, and increased risk of cancer, diabetes, infections, osteoarthritis, and osteoporosis accompanied by a decrease in height due to decreased intervertebral space. Intrinsic ageing The immutable effects of chronologic ageing, e.g., atrophy-attenuation of epidermis, retraction of rete pegs, decreased number of Langerhans’ cells and melanocytes, general decay of structural dermal and epidermal components Extrinsic ageing Effects of external factors, e.g., sunlight, smoking, gravity and gravidity, keratinocytic dysplasia, solar elastosis, and possibly carcinogenesis; intrinsic & extrinsic ageing are intimately linked and thus not divided Ageing phenomena Inevitable & immutable Cataracts, decreased skin elasticity, farsightedness, fibrous replacement of muscle, greying, poor recall, slowed intestinal transit, prostatic hypertrophy, wrinkling Inevitable but modifiable Baldness, cancer, reduced cardiac reserve, slow erection and ejaculation, decreased hearing, immunity, and vision, increased weight, liver spots (age spots), osteoporosis, decreased short-term memory, decreased stamina ageingThe gradual accumulation of minor bodily injuries or degenerations often associated with a gradual decrease in functional capacity, that affects all human beings, to a greater or lesser degree, after middle age.ageingthe process of growing old or developing the characteristics associated with old age; the process involves increased susceptibility to age-related diseases and a decline in physiological vigour. It is known that there is a genetic basis to ageing and LONGEVITY in different organisms.Patient discussion about ageingQ. I would like to know the best age for pregnancy?
