Is there anyone who knows about disability?

Hello my dear friend....

There are two words i.e. ability and disability.

Here ability means that you are able to do something for example you are able to run, you are able to think, you are able to control on your hand etc.
Disability is the opposite word of ability i.e. if a person can't run, can't walk, can't do any work which can be done by a normal person then this situation is called disability.
