People were not identified as having a disability based on a medical condition. Rather we are disabled by an environment that erects barriers to our participation in social and economic life. Physical barriers could mean steps to an entrance, uneven pathways, or long distances from one section of the premises to another. Social barriers include prejudices, pity, isolating of people with disabilities or overprotecting them. Disability is not an all-or-nothing concept. It ranged from mild to severe, it could be constant or episodic, seen or unseen, or even temporary, like a broken limb.
