The question as we read it, is interpreted differently by different people. The definition has been debatable for a long time.
A normal person would define it as the inability to perform some activities due to impairment. Disability can be mental or physical.
It can again further be categorized into acquired and developmental.
A person can be declared disable and can vouch for the various facilities and flexibilities allotted to them, but disability depends on its kind.
At one hand disability might lead to embarrassment, at the other it might be an advantage over the others!
Disables are usually treated as outsiders in the society because of the notion that they cannot do anything. Disability has affected the society much like racism. It should be understood that though they cannot perform certain activities in the ‘normal’ way doesn’t infer that they aren’t a part of the society!!
The following are the two main types of disabilities:
Physical Disability. Such disabilities involve impairment of a limb or organ. Examples are blindness, cripple, polio etc.
i. Acquired disability is a permanent impairment experienced as a result of some accident or mishap. It may not have been present at the time of birth.
ii. Developmental disability is the impairment that one either is born with or acquires it before the age of 22.
Mental Disability refers to any mental retardation or mental deficiency. This is a disorder of the brain which leads to improper or abnormal reactions and moods.
