What is the meaning of disability?

disability is a physical or mental impairment that substantially limits one or more major life activities, such as walking, seeing, learning and working. Disability includes a record of such impairment or the fact of being regarded as having such impairment. The Americans with Disabilities Act (ADA) protects individuals with disabilities from various forms of discrimination in employment, public services, transportation, public accommodations and telecommunication services. A person abusing illegal drugs or alcohol is not covered, but a person who is rehabilitated in these areas may be protected under ADA. (See handicap).
