The aging of a population is a measure for social and fiscal planning. This is because it is important for indicating the weight of the elderly population to social security health and economic systems in the society. During this measurement, scientists use the individual attributes to get information. This article has explained the four dimensions of aging.
The Chronological Age
This is defined as the period a person has lived since they were born. It is simply the number of years one has lived since they were born. It is the age measured in terms of years, months and days; hence, it is the primary way of defining age. Similarly, this is a significant aspect of mortality, chronic conditions and other damage to bodily purposes, such as memory and hearing. Scientists use this to measure the life expectancy of a population.
The Biological Aging
This are physical changes that the body goes through. It is basically the accumulation of damages to various body tissues and cells. According to scientists, people tend to slow down when they get into their middle or older years. For instance, one can develop lungs complications where they develop difficulties in breathing. This is just a biological change taking place in the body due to age.
This includes the psychological changes that take place in a person’s life, including the personality and mental functioning. For instance, decreased speed in retrieving and encoding of information is a common cause of memory loss. Therefore, some older people may develop dementia and other intellectual inabilities.
This is explained as the changes in an individual’s relationships and roles. It includes those within the web of friends and relatives, and even formal places such as workplace and places of worship.
This dimension can differ within individuals. However, it is mainly influenced by how the society perceives aging. A person will experience positive social aging if the society perceives it positively.
