Help me to write a speech on "contributions of differently abled people in different fields".

Dear Student,
                                                                   Contributions of differently-abled people in different fields

‘Differently-abled is a person who has an impairment that produces functional limitations, restrictions in activities or has social handicap’. Being differently-abled is a complex phenomenon that reflects an interaction between the features of a person’s body and the features of the society in which he or she lives. Such persons are seen as being restricted in performing daily activities because of a complex set of interrelating factors, some pertaining to the person and some to the environment and social/political arrangements. Giulio and Filipov, report that the social concept of disability introduces the notion that society has erected barriers, physical or attitudinal, which affect a differently-abled person’s life. Also, comparative dimensions or the cultural and social welfare differences influence the well-being of families with disabled in different contexts. In the past three decades, the concept of disability has shifted from individual impairment to a more social phenomenon. Singh, reports that the essential basis of disability studies is that, disability is a culturally fabricated narrative of the body, a system that produces subjects by differentiating and marking bodies.

Disability is any restriction or lack (resulting from an impairment) of ability to perform an activity in the manner or within the range considered normal for a human being.

Handicap is a disadvantage for a given individual, resulting from an impairment or a disability that limits or prevents the fulfillment of a role that is normal (depending on age, sex, and social and cultural factors) for that individual, and impairment is any loss or abnormality of a psychological, physiological or anatomical structure or function.
