It gauges one's ability to perform the physical tasks of daily life and the ease with which these tasks are performed.PFC declines with advancing age to result in frailty, cognitive disorders, and/or physical disorders, all of which may lead to labeling individuals as disabled.Disability, as well as other concepts including: abnormal, non-normal, and normalcy came from this.With the rise of eugenics in the latter part of the nineteenth century, such deviations were viewed as dangerous to the health of entire populations.In the early 1970s, disability activists began to challenge how society treated disabled people and the medical approach to disability.Due to this work, physical barriers to access were identified.At the end of the Second World War, with the example of Nazi eugenics, eugenics faded from public discourse, and increasingly disability cohered into a set of attributes that medicine could attend to – whether through augmentation, rehabilitation, or treatment.In both contemporary and modern history, disability was often viewed as a by-product of incest between first-degree relatives or second-degree relatives.
The European Enlightenment's emphases on knowledge derived from reason and on the value of natural science to human progress helped spawn the birth of institutions and associated knowledge systems that observed and categorized human beings; among these, the ones significant to the development of today's concepts of disability were asylums, clinics, and, prisons.
Or the term may serve to refer to the identity of disabled people.
Physiological functional capacity (PFC) is a related term that describes an individual's performance level.
Quetelet postulated that one could take the sum of all people's attributes in a given population (such as their height or weight) and find their average, and that this figure should serve as a norm toward which all should aspire.
This idea of a statistical norm threads through the rapid take up of statistics gathering by Britain, United States, and the Western European states during this time period, and it is tied to the rise of eugenics.
