God created Man, a complete life form that is capable of taking care of itself. Man created an environment to suit his needs like shelter, vehicles, factories etc. While creating this environment he caused pollution, destroying nature and unknowingly harmed himself in numerous ways, causing disabilities to body and mind. Accidents of any kind may occur anywhere and anyhow, making a normal person handicapped either physically or mentally.
A person can either be born disable or become disable or become disabled by accident. In both cases the person suffers great pain due to his inability to function as a normal being. This sometimes may lead to drastic action by the person, which on the other hand causes stress to his/her near and dear ones.
